Passion Fruit Farming Guide

Once the passion fruit has matured, it generally needs to be stored or transported to the markets. The tough outer skin makes transportation easier as it does not break easily. This also means that with the right conditions, passion fruits can be stored for a relatively longer duration of time.

For the purple passion fruits, the ideal stage for transportation to the markets is when the skins are still light purple in colour. This is the period when the passion fruit has begun to ripen but the skin is still relatively tough and unlikely to be compromised.

Know the Right Time to Harvest to Avoid Ruining the Flavour!

The respiration on the passion fruit during the ripening stage occurs when the passion fruit is still stuck on the vine. If you harvest the passion fruit earlier when the fruits are still green or just about to turn purple, it is going to have an unripe flavour and it is also not going to have the desired sweet natural aroma.

Generally, once the passion fruits have ripen, they can be harvested by lightly shaking off the vines and they will fall off easily on the ground. There are cases where farmers leave fully coloured passion fruit to abscise and fall on their own and be picked on the ground.

This is, however, not the ideal situation as it might lead to losses to the birds and some may even get spoilt if they are not picked just as they mature and are ripe. The passion fruit that is picked on the ground may have certain risks. It can have impact injury on the skin as well as scarring damage that may accelerate the rot. It will lead to rapid water loss in the passion fruit and there is a higher chance of it acquiring disease or fungal infections making it unfit for human consumption.

The Grading, Sizes and Packing of Your Passion Fruit Harvest

The ideal diameter for your purple passion fruits should 5cm to 8cm or 2 inches to 3 inches. For the yellow passion fruits, the ideal diameter should be 6cm to 8cm or 2.5 inches to 3 inches.

If the fruits are smaller in size, they should be classified under a lower grade and labelled so. Depending on the variety of the passion fruit, the ideal passion fruit skin colour should be full yellow or full purple. The skin colour for the hybrid passion fruit variety will vary.

Clean the Passion Fruit

Before storing your passion fruit, make sure that fruit is cleaned to get rid of dirt, surface stains or any adhering calyx as well as other tissue on the passion fruit skin surface.

Remove the dried calyx from the passion fruit as it is generally one of the main sources of decay of the passion fruit. For export or retail customers, the passion fruit is generally packed in 6Kg and 4.5Kg fibreboard cartons. There are cases when the passion fruit can be packed in one-layer or two-layer trays or cell packs.

In case the stem is attached to the passion fruit to the fruit, take extra care precaution so that the stem does not rub against the skin of the other passion fruits in the carton and cause bruising on the skin.

The Pre-Cooling Conditions for Passion Fruits

You can room cool or forced air cool at a temperature of 10 degrees Celsius.

Optimal Storage Conditions for Passion Fruits

Store your yellow passion fruits at a temperature of 7 degrees Celsius to 10 degrees Celsius or 45degrees Fahrenheit to 50 degrees Fahrenheit with a relative humidity of 90% to 95%. In this condition, the passion fruits can have a storage life of two weeks.

The purple passion fruits on the other hand are quite tolerant to chilled conditions and can thus be stored at temperatures of 3°C to 5°C or 37°F to 45°F for a duration of three to five weeks. So the purple passion fruits can stay fresh for close to two months when stored in the right conditions.

Controlled Packing Practices

There are techniques that farmers and retailers generally use to further extend the lifespan of the passion fruits. For example, film bagging and adding various coatings will significantly reduce water loss in the purple and yellow passion fruits.

Some retailers use a paraffin-based or a carnauba-based coating or even a wax coating on purple passion fruit before they are packed for storage or shipping. Doing this not only improves the passion fruit gloss which makes it more attractive to customers but it also helps in reducing the water loss in the passion fruit and also significantly extends the post-harvest life span of the passion fruit.

You can apply wax on the skin of the passion fruit it on the skin, applying the wax with a brush or simply rubbing it gently on the skin of the purple passion fruits.

Passion Fruit Retail and Display

On the shelves of the supermarkets, the passion fruits should be displayed at the room temperature. Avoid icing or misting the passion fruit on the display.

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.
