Soursop
Soursop tree care involves copious mulching, which benefits the shallow root system. Overly high temps from 80-90 degrees F. and low relative humidity cause pollination issues while lower temps (in the 70’s) and 80% relative humidity improve pollination.
Soursop trees should be irrigated regularly to prevent stress, which will cause leaf drop.
Fertilize every quarter of the year with a 10-10-10 NPK at ½ pound per year for the first year, 1 pound the second, and 3 pounds for every year thereafter.
