No seed company in Kenya is currently selling passion fruit seeds. However, if you want to grow passion fruit, you have to find a way of getting your own seeds. If you intend to grow your own yellow passion, your job of getting suitable seeds a bit easier. All you need to do is to walk into any fresh produce market or supermarket and buy a number of fresh, healthy yellow passion fruit.

Passion fruit seed extraction steps

  • When you get home, cut the fruit into two, and extract the passion fruit seeds and juice using a spoon.
  • Place the pulp in a kitchen sieve to separate the juice from the passion fruit seeds.
  • Using a spoon separate the juice from the fruit. You can drink the juice, but retain the seeds for the next step.
  • Wash the passion fruit seed to remove the remaining pulpy material that did not come off during sieving.
  • After washing the passion fruit seeds dry them for 2-3 days before washing them again and drying them in the sun.

Planting the Passion Fruit seeds

  • If you plant the seeds in a nursery immediately, the passion fruit seeds should germinate in 18-20 days.
  • Once the seeds germinate and they are about 1-2 cm high, transplant them into polythene plastic tubes filled with a mixture of soil and manure at a ratio of 1:1.
  • Don’t forget to water the polythene tubes containing soil mixed with manure before transplanting the small seedlings.
  • The polythene tubes will act as a further protection for the delicate germinated passion plants.
  • If they are transplanted to the open field when they are too young, they may not survive—that is why we need to plant them in polythene tubes.
  • If you intend to grow yellow passion fruits, once the germinated plants attain a height of 15-20 centimeter they are ready for transplanting to the field. However, if you intend to grow purple passion fruit, you have one more step of grafting to complete before your seedlings are ready for the field. You need to graft purple passion fruit on the yellow passion fruit rootstock.

So the next step for grafting purple passion fruit is as follows:

Collect scions from a mature healthy passion fruit plant. The scions you collect should have the following qualities. The scions should have 3-4 buds. The scion should not be too fleshy or too hard.

Qualities of yellow passion fruit rootstock that you need to consider

The rootstock should not be too tender or too hard. The rootstock should be free of diseases

The procedure of grafting passion fruit seedlings.

  • Take the rootstock plant preferably yellow passion fruit.
  • Cut the top of the stem at the height of 10 cm from the soil surface.
  • Create a vertical split 3-4 cm deep at the center of the stem of cut rootstock.
  • Create a wedge shape of a height of 3-4 cm at the bottom part of your purple passionfruit scion.
  • Insert the wedge shape part of the Scion you have just created into the split of the rootstock you made.
  • Ensure the scion and rootstock have form good contact (the outer lower skin of the scion should be aligned with the upper skin of the rootstock—i.e. the phloem vessels, and the inner whitish xylem vessels are aligned) before tying them with a plastic tape.
  • You can cover the plant with a white transparent plastic bag around the graft.
  • This will create a greenhouse effect on the Scion area and prevent from drying.
  • After 1-2 weeks, if your graft union was successful the buds on the scions will produce new growth.
  • Once the graft union has healed completely you can remove the plastic tape that had tied the graft union.
  • Once all is well, you can then transplant your grafted seedlings to your farm.
