Buy a ripe jack fruit from Kimironko, Remera or Nyabugogo areas- these are the places where one can find these strange fruits in Kigali. Other places include Kayonza district, Rwamagana and Gatsibo districts including those districts bordering with Uganda.
Pick only the largest seeds from the fruit as these will give you the earliest and highest germination that way producing the strongest seedlings.
Clear up the area meant for planting.
Sort out seeds you wish to use to bring up a seedling.
Open up a soil depth of 2cm were you are to put your seeds.
Pre-treat you seeds with warm water for 30 minutes before planting.
Sow your seeds, and then gently cover with soils.
Water to provide moisture and in 6 weeks the seeds shall have germinated into a healthy seedling.
To prepare the seeds for plating remove the thin, slimy coating around the seed and then thoroughly rinse the seeds in water to remove any remaining pulp juice or sugary residue. Pretreat the seeds with relatively hot water as this will stimulate germination.
Sow seeds at a depth of 2cm and then gently cover with soil. Germination will begin in 1 to 6 weeks or even longer if seeds were stored for a long time after collection. Water to provide moisture required for seed germination.
Direct seeding in the field is the best propagation method if the planting location is well prepared. sow several seeds in each planting hole to allow for selecting the most vigorous seedling. Care for the seedling for at least 6 to 12 months in first growth year. However watch out for boring insects like shoot boring caterpillar and also mealy bugs. The tree usually bears fruit within 18 to 30 months from transplanting and the fruits mature with in 3 to 8 months from flowering. Fertilize your growing jackfruit tree with nitrogen, phosphorus, potassium, and magnesium applied in a ratio of 8:4:2:1 to 1 ounce (30 g.) per tree at six months of age and doubling every six months up to two years of age.
Past the two year mark, growing jackfruit trees should get 35.5 ounces (1 kg.) per tree in the amount of 4:2:4:1 and is applied before and at the end of the wet season. Other jackfruit care dictates the removal of dead wood and thinning of the growing jackfruit tree. Pruning to keep the jackfruit at about 15 feet (4.5 m.) high will also facilitate harvesting.
