To restore durian tree after harvest, at least two set of leaves should be produced to be the source of nutrients and nourish the trunk. After that, the third set of leaves should be produced to allow the truck to receive the flowering substance to put forth leave-buds.
Suggestion
Restore the tree by using Mommoth Fong Do 200 cc., Mommoth Combi 200 cc. and Jib 50 cc. per 200 ltr. of water to resolve the problem of yellow, thin and few leaves from first set production.
