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

Panama Red Passionfruit Variety

Just like the Panama Gold, the Panama Red passionfruit is also a very vigorous vine known for its attractive red skin and succulent yellow flesh. This kind of passionfruit is self-pollinating so you will not have to worry too much about manual pollination using a brush in case the fruits fail to develop in time.

The Panama Red passionfruit is generally a very hardy variety and will do well in warmer conditions as well as a host of other conditions. It is best to plant these in a west-facing wall which has rich soils along with a well aerated trellis. You will need to add plenty of water during the growing months along with mulch around the roots in order to keep the soils moist.

For fertilizers, you can use chook manure or well balanced slow-release fertilizer at least twice a year. The Panama Red passionfruit vines will begin producing the fruits by the second year and a single vine can produce up to 300 fruits at optimal production. They vines will bear large beautiful red flowers at the ends of their stalk. Once they begin producing the fruits, the passionfruites can ripen  throughout the year, giving you an all-year supply of fresh passionfruit. In colder areas, the Panama Red passionfruit will generally defoliate or die. However, it will thrive in the warmer areas that meet the minimum planting requirements.

Like the Panama Gold passionfruit, the Panama Red passionfruit is highly decorative and is best planted in a place where you can flaunt it or where you would wish to highlight a certain area in your landscape. The fruits from the Panama Red passionfruit are larger, sweet and aromatic.

The Panama Red passionfruit is known for its lush green foliage, just like its Panama Gold counterpart but the difference is that it does better in the warmer climates. Once it matures, it will give an abundance of red skinned passion fruit. These fruits are larger and juicer and, as you will notice, they are also generally quite sweet! They are sweeter than many of the other traditional passionfruit varieties. They also emit a very sweet fragrance!

The fruit for the Panama Red passionfruit will be ready 6 months after planting and you will continue harvesting the fruits throughout the year. The best condition for growing the Panama Red is warmer climate and make sure that you have planted them in a sunny position. They should be planted next to an upright structure such as a fence or trellis.

Growing Panama Red Passionfruit

As already stated, the Panama Red passionfruit will do best in warm weather and in a sunny position as well as a protected position. Like the Panama Gold passionfruit, it will also need at least 7 hours of sunshine.  The plant will need good watering. The soil should be moist but not flooded or wet.

Finally, just like in all passionfruit plants, make sure that you have provided good structure or support for the passionfruit plant.
