When your jackfruit tree reaches 3 years old, repot it in a permanent container, in a mixture of 1/3 heather soil, compost or humus, 1/3 perlite and 1/3 free soil with added slow release fertilizer.
Planting a shrub or a tree in a pot
A mulch at the foot is welcome to keep freshness and humidity in summer, it also allows to keep a slight acidity in the soil and protects from the winter cold.
Still in the interest of productivity after 3 to 4 years, fertilize with a granulated fertilizer for fruit trees once a month or a liquid nutrition every week as soon as the first flowers appear. Before that number of years, use a green plant fertilizer every month from March to October.
