Frequent irrigation with good quality water can improve fruit growth and development and overall productivity. By Tripti Vashisth HLB-affected citrus trees have small and weak root systems. Though the roots are efficient in taking up water and nutrients, there are not sufficient roots to support the tree’s canopy requirement.
