Jackfruit grows as an evergreen tree with a short trunk and a dense treetop. It can easily reach heights of 10-20 metres with the trunk reaching 30-80 cm in diameter. The bark of the jackfruit tree is smooth reddish-brown and when the bark is injured a milky juice is released. The leaves on younger trees are irregularly lobed or split whilst on older trees they are rounder and dark green with a smooth leaf margin.
Position – Plant your jackfruit tree in full sun with well drained soil. It is extremely sensitive to frost and will not do well in drought.
Soil type – Jackfruit trees are not fussy about the soil conditions as it grows well in sandy and rocky soils
Fertiliser – To ensure good growth and fruit-bearing jackfruit trees need a high amount of nitrogen, phosphorous and potassium. Plant your jacket plum tree with a combination of potting soil and organic compost. Use a fertiliser with these requirements from your local hardware or nursery, and use it every 1 to 2 months while the tree is young. After that, 3 to 4 times per year is sufficient.
Use our volcanic rock dust to give your jackfruit tree the required magnesium. Otherwise, get magnesium as well for maximum fruit production.
Mulch – Mulching with pine bark will assist in maintaining the acidity of the soil. This mulch is available from Just Berry Plants.
Watering – During warm weather and the growing season, water your jackfruit tree generously 2 to 3 times a month. Jackfruit trees enjoy a constant source of moisture although they cannot tolerate wet roots as this will prevent it to bear fruit.
Pruning – Remove any dead or crossing branches and any foliage or small branches that sprout on larger branches.
Harvesting – Jackfruits ripen from March to June, April to September or June to August.
