How to Get a Good Passionfruit Yield

Passionfruit is one of the most popular horticultural crops. It is fairly easy to grow and manage and gives good yields within a period of 8 to 12 months. There are different yellow and purple passion fruit varieties that you can also grow depending on your elevation and local climate.

To get the best passion fruit yields, it is advisable to follow certain best practices in passion fruit planting. The propagation can be achieved through prop grafted prop gules, cloning or even seeds. Grafting is generally the most preferred option for growing your passion fruits.

By following the best practices in passionfruit farming, it is possible to harvest as much as 10 tons of passion fruits in a single season and this can fetch lots of money in the market.

Here are some of the best practices that you should keep in mind if you are looking for optimal passionfruit yield:-

Seed Extraction

To extract the seeds, collect healthy and mature fruits from the parent passionfruit plant and scoop the seeds from the ripe fruits. Put the extracted seeds in water for about 3 days so as to separate the seeds from the pulp. Dry the seeds under a shade and store them in a cool and dry dark place. This will ensure there is no loss in the viability of the seeds.

The passionfruit seeds can either be planted in a prepared seed bed or wide bags measuring 6cm that are filled with sterilized soil. The soil sterilization can be achieved by passing steam through the soil. This will kill off the parasitic nematodes and other soil-borne pathogens that cause diseases.

Land Preparation

You can prepare the land by slashing way the shrubs and tall grasses. Alternatively, you can use herbicides in order to get rid of the weeds. Then dig 30cm by 30cm holes on the garden. The soil that is scooped from the hole should be mixed with some manure and then poured back into the hole.

The spacing for the holes should be 3cm by 3cm apart. With this, an acre of land will accommodate anywhere from 550 to 600 passionfruit plants.

When you are planting the passionfruit seedlings, open a small hole in each of the holes and add 5 grams of fertilizer such as a diammonium phosphate fertilizer and cover this slightly. Then plant your passionfruit seedlings on the hole.

The passion fruit seedlings should be planted at the onset of rains and the planting should be done early in the morning or late in the evening. This will help reduce the heat stress on the plants. Plant the passion fruit seedlings in an area that receives sufficient sunlight.

Fertilizing the Gardens

A month after planting, you can apply a nitrogen, phosphorous and potassium fertilizer. This should be applied in a ring that is dug around the plant. The application should be done every two months until the passion fruits reach the flowering point.

After the passion fruit plants have started flowering, apply only the potassium fertilizers as these will help in the flower formation.

Best Farm Practices When Growing Passion Fruits

There are certain farm practices that you will need to incorporate for the optimal growth of your passionfruit plants.  These include trellising the plants and running plastic ropes around the poles and sideway trellising systems. The ropes should be running horizontally while the passion fruit plants should spread sideways.

There is advantage with using sideways trellising. It will allow the passionfruit plants to spread optimally and this will allow room for the plants to be exposed to sufficient sunlight. While trellising is a must, don’t make it too elaborate as this will lead to an accumulation of shed which may end up inhibiting exposure to sunshine thus affecting the plant growth.

You should also spray the passion fruit plants with pesticides so as to stop a pest infestation.

Overall, passion fruit plants generally require dedication, care supervision. You have to be on the lookout for any anomalies and correct them to ensure the optimal growth of your passion fruit plants right from the nursery stage to the harvesting stage.

Growing Passion Fruit: Factors to Keep in Mind

Whatever the variety of passion fruit that you are planning to grow, there are various common guidelines that you will need to keep in mind. These include the following:-

The Selection of Site: Proper site selection must be carried out when you are planning to grow your passion fruit. It is important to choose a site which has well-drained, fertile as well loamy soil. It is also important to choose a site that is well-protected by effective windbreaks. Where the soil is not fertile, you can use manure such as organic or chook manure. If you are using commercial fertilizers, these should be well balanced.

Preparation of the ground: In order to increase the depth of the soil, it is important to mound the rows where you will be planting the passion fruit. Good drainage of the planting area is also essential. Once you have prepared the soil, you can add organic matter or compost manure in order to further nourish the soil.

As part of the site preparation, you can also erect a vertical T-trellis on the site. Make sure that the spacing between each row is at least 3m so as to allow vehicle access when you will be harvesting the passion fruit. The spacing between each of the passion plants should be between 4-6m. When planting, add a thick layer of organic mulch in order to minimize the growth of weeds and prevent water loss. The mulch should be replaced on a regular basis in order to maintain optimal soil structure for the growth of the passion fruit.

Planting material: You can plant either seeds or true type. Whether you are planting seeds or grafting, it is important to ensure that these are selected from a good fruit. For additional information on how to plant any of these, please check our Passion Fruit Farming Handbook PDF copy.

Irrigation: To ensure optimal moisture supply during the dry seasons, you will need to irrigate your passion fruit plants sparingly.  Use either drip irrigation system or micro-jets. As we have repeatedly stressed, it is important to keep the soil moist but never wet. You can observe the soil profile in order to determine if there is the right amount of moisture in the soil. It only needs to be moist but not wet.  Add water daily. Mature vines generally require a large amount of water. It is very important that the passion fruit tendrils do not suffer water stress as this will cut down on the yield. The water should be fresh as passion fruit plants are intolerant to salt.

Nutrition: Before planting your passion fruit plants, it is important to have soil analysis carried out on the site. This should be done at least 6 months before you plant so that you can adjust the soil conditions accordingly. For example, the soil PH should be somewhere between 5.5 to 6.5. If the soil is too acidic, you can add little amounts of base fertilizers as well as compost manure in order to raise the soil PH.

Pests: Check out a comprehensive list of passion fruit pests and control measures on our Passion Fruit Farming Handbook.

Diseases: There are various kinds of diseases that can affect your passion fruit plants such as scab, passion fruit woodiness virus, fusarium wilt, brown spot and many others. Check out the various passion fruit diseases as well as the prevention and management measures on our Passion Fruit Farming PDF handbook.

Pruning your passion fruit: Pruning your passion fruit plants is an important plant management measure that you must take as early as possible in order to ensure optimal plant growth. It is important to begin training the passion fruit vines as early on as possible. Train them to the top of the trellis or fencing wire and then remove the vertical shoots so as to allow the lateral shoots to begin sprouting vigorously.

It is also important to ensure that you remove the dead foliage or diseased foliage from the passion fruit plant. All lateral shoots that touch the ground should be pruned off. You can also replant your passion fruit after every two to three years.

How to Make Your Passion Fruit Yield More Fruit

The yield from your passion fruit plants will gradually drop with time. If the vines have been standing for at least three years, you are likely to see a drastic drop in the yield of your passion fruit plants and it is therefore advisable to replant them after this duration.

This drastic drop in the yield will most likely occur in the regions with punishing climates or where there is a high incidence of the diseases and pests that affect passionfruit plants. Over time, that vigorous growth and harvest is stunted and the plant is unable to hit its previous yields even if you apply fertilisers.

If you are not ready to replant, you can also apply some good crop husbandry in order to boost the yield of passion fruit vines. For example, make sure that you prune off the old and unproductive dead wood and shoots on the passion fruit vines. Remove all the secondary shoots that touch the ground and make sure you offer the passion fruit plant’s laterals excellent support through the trellis. It is these parts that bear the fruit and if they are not adequately supported, your yield is going to suffer.

When pruning your passion fruit vines, wash your hands with a disinfectant and make sure that the equipment or tools that you are using to prune off the plant is also disinfected. This will prevent the spread of diseases through all your passion fruit plants.

It is also advisable to apply fertilizers on a regular basis but don’t overdo. Add some compost at the root of the passion fruit plants. These not only retain the moisture but the organic matter also nourishes the passion fruit plant. You can also apply the foliar feed sprays every month after you have planted the passion fruit plant. Continue applying this for at least three months.

Finally, apply some fungicides on your passion fruit plants to kill off most of the fungal diseases that are likely to stunt the growth of your passion fruit plants and your yields. This will also forestall any future fungal disease outbreaks.

Harvesting Passion Fruit

Passion fruit vine is a tropical to sub-tropical plant that thrives in warm climate and cannot tolerate freezing temperatures. There are two kinds of passion fruit – purple and yellow. The purple kind ripens earlier than its yellow counterpart. Actually, the ripening time for passion fruits depends upon the species, climatic conditions and the time of its planting.

How to decide the best time for picking the fruit

Passion fruit has variable ripening time. The purple variety is more tolerant to cooler climate and ripens much later than the yellow passion fruit. Crops growing in warmer areas have a quicker ripening period.

Fruits start to grow on vines that are around a year old or in some cases three years. However, warmer regions may see an early crop. The yellow passion fruit blooms from April to November and the purple species from March through April. The fruit bearing and ripening is after 70-80 days after pollination. This technically implies that the purple variety is ready for picking by end of summer and early fall. The yellow passion fruit is ready for harvesting in winter.

Harvesting passion fruit

Passion fruit is one that does not need monitoring for harvesting, as the fruit is seldom plucked from the vine. It is a clear indication that the passion fruit is ready for harvesting when it falls off the vine on its own after totally ripe. So as such, passion fruit is collected from the ground and then consumed or processed. Falling from the vine has no major impact on the fruit and it does not get damaged. One just needs to pick it up soon enough so that it does not get shriveled up by heat.

You know the time has come to harvest the fruit from the vine when it turns plump and has a wonderful shade of golden yellow or deep purple. Initially the raw passion fruits are green in color. Slightly wrinkled fruits are over ripe and are much sweeter in taste and rich in aroma.

In order to detect the fallen fruit, it is advisable to keep the area under the vines clear at all times. While picking ripe fruits from the vine, a gentle twist is all that is needed to separate the fruit from the vine. Green passion fruits will not ripen well after picking. However, the ripe ones get sweeter and have deeper flavor if left untouched for long time.

Storage and usage of passion fruit

The fruit that has been harvested needs to be stored well for prolonged use. After picking, the fruit can remain in the refrigerator for more than a week. However, it needs to be placed in a box or crate for the air to circulate freely and keep the fruits fresh. Storing the fruits in bags may hamper aeration and thus mold can form on the fruits making them inedible.

For long time storage, it is better to wash and dry the fruits and then put them in mesh bags and store in the crisper compartment in the refrigerator. Commercial growers need to preserve fruit for marketing or export and thus they coat the fruit with paraffin wax so that it remains fresh and undamaged while shipping. The fruit remains fresh for around 30 days in the coated condition.

Passion fruit tastes best when fully ripe and for this you can leave the ripe, picked fruit on the kitchen counter and allow maturing it a bit more. It will be noticed that the fruit is sweeter and has more balanced taste.

Being an aromatic fruit, passion fruit has many uses in culinary art. The most common being juice or squash. Nonetheless, the fruit adds great flavor to desserts, ice-creams and variety of dishes.

Passion Fruit Farming Guide

The passion fruit or passionfruit as it is called in Australia and New Zealand is one of the most common backyard fruits. It is sweet and has excellent nutritional value that will contribute vastly to the good health of your family. Passion fruit farming, as a result, is one of the most profitable horticultural ventures that one can engage in.

Passion Fruit Farming Tips

There are various ways in which you can grow your passion fruit. There are people who will grow it from a seed but most farmers rather prefer growing them grafted plants or transplants. Passion fruit not only gives it sweet passion fruits but it can also be a nice ornamental plant when it is grown in your backyard. Its large purple and white flowers will contribute to the aesthetics of your outdoor areas or gardens and it also produces its much beloved purple black fruits.

How to Get Started With Passion Fruit Farming

In order to ensure good growth as well as bountiful harvest for your passion fruit, it is important to plant them in a sunny and frost-free area and then give them lots of tender loving care. In order to grow lavishly and produce lots of fruits, passion fruits will need to develop an extensive root network so you need to give them lots of space for the root development.

Additionally, the surrounding area where you are doing passion fruit farming should be kept free of weeds and various other competing plants that might deplete the soil of important nutrients. Give the passion fruit vines enough space to climb. A single passion fruit can reach a length of up to 2.5m across and will be several meters high.

Some of the most ideal places where you can grow your passion fruits include along wire fences or even across a balcony. You can also grow them over a pergola so that they can offer you shade throughout the year.

Growing Passion Fruit Along a Sunny Wall or Fence

In case you are planning to grow your passion fruit along a sunny wall or fencing, then it is important to install the wire, trellis or mesh that will provide support for the tendrils. Take into account the root system of the passion fruits knowing that will require deep soils in order to support the extensive network of root system for your passion fruits.

The fertilizer much should be spread over the entire root system of the passion fruit plant. Passion fruit plants can adequately survive on organic fertilizers such as the pelletised chicken manure. You can also use any other kinds of fertilizers which are designed to promote the flowering as well as the fruiting of the passion fruits. The fertilizers should be applied during spring and then after every four weeks during the summers. When applying fertilizers to the passion fruit plants, make sure that you water the plant well.

In order for a newly planted passion fruit plant to hit its full fruiting size, you are likely to wait for between 12 and 18 months.

Watering and Pruning Your Passion Fruit

The passionfruit vines generally do very well where they are well-watered. Water is especially important when they have been newly planted as well as when the passion fruit is flowering and beginning to form the passion fruit.

Unlike other vines with extensive stem network, passion fruit plants do not require any unique pruning techniques in order for them to begin producing the passion fruit. The pruning can be performed in order to control their spread as well as their size. The pruning also allows sunlight to filter through the passion fruit vines so as to help in ripening the passion fruit.

When the passion fruits are pruned, they will begin experiencing a strong new growth that will help in the production of fruit. Where the passion fruit plants are fairly well established and have also fruited, it is important to have them pruned before flowering. This will get rid of excessive growth and prevent the huge tangling of the stems when they are developing naturally.

Before cutting any stem, follow it carefully in order to ensure you are not getting rid of a major stem that is likely to produce fruit. If there is excessive growth, you can tie this to the support or trellis. Alternatively, you can simply cut off the branches that are wayward.

Growing Passion Fruit: Tips and Information

Passion fruit is a fast growing tropical plant that is fairly easy to grow. Once you have fertile and well aerated soils as well as excellent access to water supply, you can expect to see your passion fruit plants doing very well.

Passion fruit is a climbing vine and growing passion fruit will need some tender loving care and support for healthy growth and yields in your backyard. Passion fruit is generally a very vigorous plant that grows very fast. Within a very short time, it will have bloomed quickly and created numerous stems and leaves.

Like sweet potatoes, the passion fruit vines will create very large and lobed leaves that sprout out of little tendrils. These tendrils will wrap themselves around whatever form of support that they can find. You will need to provide very good support for these tendrils using various techniques in order to allow them to bloom as naturally as possible.

Passion Fruit Varieties

There are various varieties of passion fruit that you can plant in your geographical location. In our passion fruit farming handbook, we have covered the various varieties of passion fruit that you can grow in various locations including what variety to plant in Australia, New Zealand, South Africa, India, Kenya, East Africa, Central Africa, West Africa, the United States and South America.

In the cooler climates, commercial passion fruit farmers generally use hybrid varieties of the golden and purple passion fruits. These plants are generally better at tolerating the older climatic conditions. However, passion fruit performs best in the tropical climates.

Some of the hybrid passion fruit varieties that you can grow in Australia include Lacey, PurpleGold, Panama and SuperSweet amongst others. Check out our passion fruit guide PDF copy for your country for information on the right variety of passion fruit to grow in your country along with information on their characteristics.

Yellow Passion Fruit Variety

You will notice that there are certain varieties that are better suited for the tropical climates such as the flavicarpa passion fruit varieties. For cooler climates, you will be better off with the purple passion fruits or some of the hybrid cultivars varieties. All these varieties and their characteristics are covered in our passion fruit farming handbook.

Important Things to Keep in Mind When Growing Passion Fruit

They need lots of nutrients: Passion fruit plants grow very fast and, therefore, need an abundant supply of nutrients in order to support that growth. You will notice that your passion fruit plants have a very lush foliage within a very short time and that must come from somewhere. Without adequate water and nutrients supply, your passion fruit plants might reach maturity and still not produce any fruit. Growing passion fruit vines will require fertile soils and additional fertilizers, preferably the compost manure type. However, don’t overuse the fertilizers otherwise you might prevent or delay the formation of the fruits.

Passion fruits require lots of sunshine: For the best performance, growing passion fruit requires lots of access to sunshine, a warm climate as well as adequate protection from windy conditions. An ideal planting area for your passion fruit is a sunny and sheltered site that is also free from frosty conditions. Some purple varieties of passion fruit can handle mildly frosty conditions. While frost may kill the top of the vines, the roots generally reshoot but passion fruits grow excellently in warmer conditions.

Support: Because the passion fruit tendrils are very long and thin, they will need something that they can climb over. This can be a wall, fence or even poles.

The root systems are vulnerable: The root network of passion fruit is generally quite vulnerable. The best soil for growing passion fruits is generally a healthy soil with lots of worms, microbes as well as various organic matter.  If you grow passion fruit in poor soils, they are likely to wilt, experience root rot or be susceptible to nematodes. Heavy clay soils, for example, are generally not ideal for passion fruit growing.

Watering passion fruit: When growing passion fruit, it is important to ensure that the plants are well watered. Passion fruit is a large plant and is supported by a very small root system. The roots will not dig deeper like those of the other trees. You, therefore, need to supplement their water requirements by making sure that the plant is well watered. Water is especially important when the plants are fruiting. While passion fruit plants need plenty of water, they cannot handle soils that are waterlogged so water them sparingly like you would water your vegetable gardens. The site where you are growing passion fruit should also be one that drains easily.

How to Grow the Passion Fruit Seeds

Buying passion fruit vines is generally costly so some farmers prefer to grow the passion  fruit plants from the seeds in order to cut down on costs. However, when you are growing from the seeds, it is important to ensure that the seeds are fresh. You can purchase seeds from the store you can harvest seeds from the fruit itself and plant them as soon as possible. The seeds will generally take anywhere from 10 to 20 days in order to germinate. On the other hand, the older passion fruit seeds generally take a little longer in order to germinate.

Disadvantages of Planting Passion Fruit Seeds

Even though it is a cheaper option of growing passion fruit, there are many disadvantages associated with planting your passion fruit from the seeds. It is not an efficient way to grow your passion fruits because many of the seeds will not even germinate in the first place.

If you are planting seeds for hybrid passion fruit varieties, they not even grow to type as you would expect. In many cases, you will be planting the passion fruit seeds and you will not even be sure about the kind of outcome that you will get.

Another good reason not to grow passion fruit seeds yourself is that some of the passion fruit varieties are highly susceptible to various forms of root diseases such as the Fusarium wilt. If this is a problem in your kind of soil and you live in a cool climate, then you will be better off with the grafted passion fruit plants. If you live in the tropics, then you are likely safer as the tropical passion fruit plants are generally less susceptible to the Fusarium wilt and are also fairly well resistant to the nematodes.

How to Grow Your Passion Fruit Yourself

Want to grow your passion fruit yourself? Here are some useful tips to keep in mind:-

The Position of Your Passion Fruit Plants

Passion fruits are a subtropical plant so it is necessary that they are planted in a position where they receive full sun. The plants should also be sheltered from frost and winds. The soil where the passion fruits are planted should be light and properly drained. In case you live in area with heavy soils, consider planting your passion fruit plants in containers. We advise adding in an excellent quality potting mix that has been formulated well for the containers where you plan on planting your passion fruits.

Planting Your Passion Fruit

Plant your passion fruit when all the frost has subsided. If you are living in temperate climates, the best time to plant your passion fruit would be during spring. Before you plant the passion fruit, add a slow dripping citrus fertiliser in the bottom of the hole. Make sure you firm the soil well and also water the soils well.

Passionfruit Plantation

Watering Passion Fruit Plant

Passion fruit is a vigorous tropical plant that will develop an extensive network of root system but they won’t go very deep. The roots will be fairly shallow. Make sure you carry out frequent watering but without flooding the soil. Too much water is not advised for your passion fruit. Add a little water and to help in retaining the moisture, add some mulching at the root system. The watering should be done during the flowering and fruiting phase. When watering, keep the water from getting to the foliage so as to prevent the formation of fungal problems.

Adding fertilisers

Passion fruit plants, being vigorous, are also heavy feeders. Feed them sparingly with a slow release Citrus fertiliser. During their fruiting phase, you can also feed them with a liquid fertiliser.

Training and Pruning Your Passion Fruit

The passion fruit plants should be trained early on. This will allow them to create a strong framework upon which other lateral branches will sprout and bear the fruit. After planting the passion fruit vine, it is advisable to get rid of the side shoots so that you can train the main shoot or the leader towards the trellis so as to ensure excellent support.

After the growing tip has sprouted a bit, pinch out the growing tip so as to allow the sprouting of the laterals. If you live in a temperate climate, never prune during the winter. In much of South East Asia and even Australia, the best time to prune your passion fruit plants would be around October or November.

During the early pruning, you are going to lose a few flowers and possibly fruits but the passion fruit plants have a very vigorous growth so they will more than make up for any losses.

Fruits

The passion fruit plants generally bear fruits in a very short period of time, on average 8 to 9 months. Your passion fruit plants will ripen from around mid summer. The passion fruit plants will be ripe when their skins turn to purple or yellow depending on the variety of the passion fruit plant. During the summers, consistent watering is also necessary so as to prevent the passion fruits from dropping off the plant prematurely. Less water for the plant will also lead to wrinkled fruits.

Passion fruit plants are fairly easy to grow if you follow the right procedures. Check out our Passion Fruit Farming Guide for comprehensive guidance on how to grow your passion fruit plants. You can order your copy via PayPal by paying $10 to freerangefarming.info@gmail.com.

Passion Fruit Farming in Uganda: Quick Tips for Success

Looking for some quick tips for passion fruit farming success in Uganda? Here we go. A 2 minute read of simple tips that will make your passion fruit farming venture more profitable:-

  • Plough the proposed deeply and thoroughly. This will open up the soil and allow it to be aerated which is ideal for passion fruit planting. Opening up the soil also allows for water filtration.
  • Open the passion fruit planting holes several weeks in advance.
  • Mix the top soil of the farm with the compost or manure and then put it back into the planting hole.
  • Transplant your passion fruit seedlings as soon as the rains begin. If there are no rains, water before and after planting your passion fruit.
  • You should do the transplanting of the passion fruits during the early mornings or late evenings. This will minimise the likelihood of plant failure or withering due to excess heat.

 

Planting from Seeds

  • If you are starting with seeds, soak these seeds in warm water so as to facilitate their quick germination.
  • Leave the passion fruit seeds in the open air to dry before you plant.
  • Place the passion fruit seeds 1cm deep in polythene containers
  • Thinly cover the seeds with top soil and then pour water to facilitate germination.
  • After the seedlings have grown to a height of 20cm to 25cm, transplant them to the prepared site. Make sure you remove and dispose of the polythene containers.
  • Harvest your passion fruits when they ripen and change colour to either yellow or purple depending on the passion fruit variety.

How to Graft Passion Fruit For Better Productivity

Yellow passionfruit does not have to be grafted. It can grow on its own roots without significant infection by Fusarium.  It can be planted directly into the commercial fruit orchard.

If purple passionfruit is being grown for the fresh market, it needs to be grafted onto the yellow rootstock before planting out.  The two seedlings to be grafted together need to have the same thickness of stem to make the grafting easier.  This means they may not be the same age, as the yellow seedlings are usually more vigorous growers and may be bigger than the purple passionfruit seedling of the same age.  Choose the same size of seedlings, each with stems about a ‘pencil thick’ to graft together.

The pink-flowered banana passionfruit (Passiflora millissima), appears to be resistant to root rot and, when used as a rootstock, also induced a measure of resistance in the purple passionfruit to grease spot (Pseudomonas passiflorae) a serious bacterial disease.

Grafting is an important means of perpetuating hybrids and reducing nematode damage and diseases by utilizing the resistant yellow passion fruit rootstock.

For grafting, you will need the yellow passion fruit rootstock and the purple passion fruit scion. The scion refers to a part of the stem that has been snipped from the parent plant. The scion will be attached to the stem section of the second plant so as to form a grafted union.

This grafted union will callus over gradually and morph into a single plant that grows normally. The new grafted plant will have the qualities of both its parent plants.

Here is a guide to grafting your purple passion fruit:-

  • Make sure the rootstocks and the scions are well irrigated up to 2 hours before the grafting is done.
  • Soak the blade of the grafting knife in a mixture of water and bleach for up to 10 minutes and allow it to dry before you begin using it to cut or splice the scions and rootstocks.
  • Make a wide angled cut into the main stem of the yellow passion fruit rootstock using the utility knife. The cut should be 1 ½ inches long and should be made 10 to 12 inches above the soil.  After making the cut, wipe the blade of your utility knife with a cloth dipped in a disinfectant such as isopropyl alcohol.
  • Remove a three to four inches of the main stem of your purple passion fruit seedlings. Make sure every seedling or scion has at least two leaf nodes. Make a wide angled 1 ½ inch cut on the stem of the seedling using your utility knife.
  • Position the cut surface of your purple passion fruit scion against the cut surface of the yellow passion fruit rootstock to make a union. Wrap this union tightly using a grafting tape.

Cleft Grafting for Passion Fruits

  • Put an opaque plastic bag over the grafted plant. Secure this plastic bag on the rootstock just below the graft union. You can do this by tying it up with a piece of twine.
  • Put the passion fruit grafted union in a shaded area with temperatures not exceeding 65F.
  • The graft union will fully form after 10 to 14 days. Remove the twine after this graft union has occurred.  Open the bag to allow the flow of air. After the buds have started forming on the purple passion fruit scion, get rid of the plastic bag entirely.

Tools to Use

  • Utility Knife
  • Grafting Tape
  • Twine
  • An Opaque Plastic Bag
  • Household bleach such as Jik or Clorox
  • Isopropyl alcohol

Different Stages in the Growth of Passion Fruit

Passion fruit is ideally grown in subtropical and tropical regions and need plenty of sunlight for a healthy growth. However, it can be grown in many other parts too with controlled soil and climatic conditions.

Passion fruit can be cultivated by two methods – first being through germination of seeds and the other being grafting of plant.

Preparation for planting

Any plant that you wish to grow needs planting in pot or ground. In the case of passion fruit, the seeds from a ripe, harvested fruit can be used after removing them from the pulp, washing and drying them for 3-4 days.

The freshly picked seeds germinate faster and better than the dried stored ones. A pot with mixture of coarse sand, manure and topsoil should be made ready for the seeds to be planted. The pot should be approximately half filled with the soil.

Digging furrows in the soil for plantation also ensure that the seeds are not drenched in water and there is sufficient scope for seepage. Sow the seeds at higher level in soil at least 1 cm apart from each other and then cover them gently with a thin layer of soil. This is necessary so that the seeds get good supply of warmth of sunlight for germination. Water the seeds immediately, taking care to see that the seeds are just moistened and not totally soaked in water. Keep an eye on the pot in next few days and as you see top layer dried, sprinkle some water to wet it.

This will enable the seeds to germinate quickly within 10-20 days. Since they are planted at higher level, there is scope for the roots to grow firmly in the soil. When you see that the seedlings have grown 8 to 10 inches tall, you can safely transplant them in the ground where you wish to cultivate them.

As far as planting through grafting is concerned, prepare a pot with three parts fertile soil with a part of topsoil. After mixing them thoroughly, plant the cutting in it. The cutting does not have roots and thus absorbs moisture from atmosphere for its growth. Hence, there is no need to water the cutting excessively nor does the soil have to retain the moisture.

For a good crop, it is essential that the cutting is from a healthy plant. Select the new, young portion of a mature vine and snip it with at least three buds intact. The cut should be directly below the lowest bud, as this is from where the roots will grow in the soil. Plant the cutting in the prepared sand bed immediately after cutting to prevent drying up.

After this stage, it is of prime importance to keep the cutting under humid condition by covering the pot with a plastic sheet and keeping it in sunlight. The roots are formed within 1-2 weeks and then it is ready for transplanting in solid ground.

Choose the right place

For a healthy plant growth, the space utilized for planting should be ideal to suit the particular plant growth. In case of Passion fruit, the plant in consideration is a vine and thus needs sufficient place to spread. The spot chosen for planting should be away from heavy root trees and weeds. It is necessary to clear the weeds from the portion before planting. There should be full sunlight (6 hours a day) and a support nearby for the vine to climb on. You can have it close to fencing or erect a trellis for the purpose.

Care and harvesting

It is essential to put fertilizers from time to time, remove the weeds and water the plants daily for a good crop. Spray the leaves with pesticides to protect from diseases. Soil check for pH balance of 6.5-7.5 is necessary too. Roots need to breathe easily for a healthy growth, so loosen the soil periodically and add coarse sand for aeration.

The vine starts bearing fruits in a year or one and half year, depending upon the quality. Both the varieties, purple and yellow, are green in color in initial stages and as they ripen they change the color. Once you see some wrinkles on the fruit it is ready for harvesting and consumption.

How to Graft Passion Fruit For Better Productivity

Yellow passionfruit does not have to be grafted. It can grow on its own roots without significant infection by Fusarium.  It can be planted directly into the commercial fruit orchard.

If purple passionfruit is being grown for the fresh market, it needs to be grafted onto the yellow rootstock before planting out.  The two seedlings to be grafted together need to have the same thickness of stem to make the grafting easier.  This means they may not be the same age, as the yellow seedlings are usually more vigorous growers and may be bigger than the purple passionfruit seedling of the same age.  Choose the same size of seedlings, each with stems about a ‘pencil thick’ to graft together.

The pink-flowered banana passionfruit (Passiflora millissima), appears to be resistant to root rot and, when used as a rootstock, also induced a measure of resistance in the purple passionfruit to grease spot (Pseudomonas passiflorae) a serious bacterial disease.

Grafting is an important means of perpetuating hybrids and reducing nematode damage and diseases by utilizing the resistant yellow passion fruit rootstock.

For grafting, you will need the yellow passion fruit rootstock and the purple passion fruit scion. The scion refers to a part of the stem that has been snipped from the parent plant. The scion will be attached to the stem section of the second plant so as to form a grafted union.

This grafted union will callus over gradually and morph into a single plant that grows normally. The new grafted plant will have the qualities of both its parent plants.

Here is a guide to grafting your purple passion fruit:-

  • Make sure the rootstocks and the scions are well irrigated up to 2 hours before the grafting is done.
  • Soak the blade of the grafting knife in a mixture of water and bleach for up to 10 minutes and allow it to dry before you begin using it to cut or splice the scions and rootstocks.
  • Make a wide angled cut into the main stem of the yellow passion fruit rootstock using the utility knife. The cut should be 1 ½ inches long and should be made 10 to 12 inches above the soil.  After making the cut, wipe the blade of your utility knife with a cloth dipped in a disinfectant such as isopropyl alcohol.
  • Remove a three to four inches of the main stem of your purple passion fruit seedlings. Make sure every seedling or scion has at least two leaf nodes. Make a wide angled 1 ½ inch cut on the stem of the seedling using your utility knife.
  • Position the cut surface of your purple passion fruit scion against the cut surface of the yellow passion fruit rootstock to make a union. Wrap this union tightly using a grafting tape.
  • Put an opaque plastic bag over the grafted plant. Secure this plastic bag on the rootstock just below the graft union. You can do this by tying it up with a piece of twine.
  • Put the passion fruit grafted union in a shaded area with temperatures not exceeding 65F.
  • The graft union will fully form after 10 to 14 days. Remove the twine after this graft union has occurred.  Open the bag to allow the flow of air. After the buds have started forming on the purple passion fruit scion, get rid of the plastic bag entirely.

Tools to Use

  • Utility Knife
  • Grafting Tape
  • Twine
  • An Opaque Plastic Bag
  • Household bleach such as Jik or Clorox
  • Isopropyl alcohol

Establishing and Grafting Your Passion Fruit Seedlings

Passion fruit plants are affected by a variety of insects and diseases that can have an adverse impact on the yield and profitability of your farm. Before venturing into passion fruit production, it is therefore important for you to have the proper knowledge and expertise on the management of your passion fruit vines so as to maximize on the production. Optimal yields are achieved through proper management and plant husbandry.

Passion Fruit Grafting

Before you venture into passion fruit farming, it is necessary to know some basics about the passion fruit crop you are going to plant.

Passion fruit seed extraction, planting and grafting

The seed extraction

The first step to establishing your passion fruit crop is seed extraction. In this process, the healthy and mature fruits of the passion fruits that have a history of excellent performance are extracted from the parent plant.

The extracted seeds are then put in water for at least three days which will allow them to ferment and make it easier to separate the passion fruit seeds from the pulp.

After extraction, the passion fruit seeds are then dried under shade. If you don’t store the passion fruit seeds in a cool, dark and dry place, they are going to lose the viability and that means the rate at which they will germinate and thrive will be quite low.

Planting your passion fruit seeds

The passion fruit seeds should be planted into a pre-prepared seed bed. Alternatively, you can also use polythene bags in planting the seedlings which will make the transplantation a lot easier. Typically, the polythene bags should be at least 6cm wide and 22.5cm high.

When planting the seeds, use soil that is sterilized so as to get rid of the nematodes that are like to afflict the passion fruit roots and kill the plants or lower their yields. Sterilised soils also eliminate the various soil borne diseases and various other harmful micro-organisms.

There are various ways in which you can carry out soil sterilisation. For example, you can use hot steam or simply expose the soil to sun for several days before planting the seeds. The germination of the passion fruit seeds will begin at least 17 days after the planting has been done.

Grafting Your Passion Fruit

The rootstock of the yellow passion fruit variety is generally used because it has excellent resistance to the nematodes and various other passion fruit diseases. The purple passion fruit varieties are generally more vulnerable to these pests and diseases. Using the yellow passion fruit rootstocks will increase the survivability of the plant.  The rootstocks should be at least 50cm high and 3 or mm thick.

After the germination, choose healthy seedlings with dark green leaves for grafting. The scions of healthy looking high yielding purple passion fruits will be used for the grafting. These should be collected when the plant has flowered. The mother plants from which you will collect the scions should be raised in an area where there is sufficient protection from insects so as to reduce the occurrences of diseases.

Make sure that the grafting equipment is sterilised so as to prevent the spread of diseases. A simple home based solution that you can use to sterilise your passion fruit grafting equipment is Clorox.

You can graft the passion fruit using the cleft technique or by splicing.

Post Grafting

After the grafting, make sure that the seedlings are watered and a hardened by exposing them to sunshine gradually.

One month after grafting, you can remove the grafting tape from the union and then transplant your seedlings in the field.

Passion Fruit Propagation

 Passion fruits can be propagated by planting the passion fruit seeds, through grafting on a resistant root stock and via cuttings. The most vigorous propagation techniques are via seeds and grafting. Here is a look at the various propagation techniques:-

Passion Fruit Seed Propagation

The passion fruit seeds should be collected from superior vines based on the quality and the yield. Extract the pulp and allow it to ferment for 72 hours and then extract the passion fruit seeds. Sow the seeds in seed beds that have been well prepared in advance.

Once the seeds have sprouted and attained four to six leaves, you can transplant them from the seed beds to smaller polybags that that contain a mixture of soil, sand and compost. Leave them here for a duration of three months after which they will be ready for transplanting in the main field or garden area.

Passion Fruit Vegetative Propagation

The best cuttings are the semi-hardwood type with a size of 30 to 35cm and with three to four nodes. These make for ideal cuttings.  Put these cuttings in the pots or sand beds for root initiation and then transfer them to the polybags where they can undergo proper root development. After a duration of three months, these rooted cuttings can then be replanted.  The main issue with the vegetative propagation is that it is quite time consuming and not very popular with many farmers.

Spacing and Planting Your Passion Fruits

The kind of spacing to leave will depend on the type of training system that you are planning to adopt as well as the variety of passion fruit that you are planting. If you are planting your passion fruits in a bower system, you can have a 3m by 3m spacing that will accommodate up to 1110 plants per hectare. On the other hand, for a Kniffin training system, a spacing of 2m by 3m would be ideal. This will accommodate up to 1666 plants per hectare.

Land Preparation

Avoid planting the passion fruits in areas that experience stronger winds. A sheltered site is generally more ideal. Strong wind will damage the passion fruit vines and have a negative impact on your yield but they may also make training your passion fruit a bit difficult. Prepare planting pits that you have filled with a top soil and compost. Do your passion fruit planting on cloudy days at the onset of rains. In India, the best planting time is in the months of May to June at the onset of monsoon rains. In the first five to six months, you can intercrop the passion fruits with seasonal vegetables such as ginger and turmeric.
