Jackfruit tap root

Manfred says...
No, but trees often don't have a tap root after they get going, where the water table is too high or the soil is too shallow. The tree will develop a healthy adventitious root system as long as the main roots aren't too bunched up when you plant it out.

Keep it well watered at first if, or you think you have cut a big percentage of the roots off, reduce the leaf area to reduce evapotranspiration loss, when planting out. On a very small, young tree you can do that by cutting each leaf by (say) two-thirds.

I think there is still a chance of it developing another taproot, mainly if it finds better moisture beneath the pot. They can even push a tap root into a porous clay if they find moisture down below. If you dont want a taproot below your potted tree then put your containers on a pallet or whatever and the taproot will not form. I put most of my trees on reused plastic pallets or upside down wire baskets. It also keeps better hygiene and improved downward flow of water through the pots..
