Q.soursop doesn’t become tender
The soursop in my plantation (in Johor, Malaysia) has a good supply (quantity) of fruit but I never get a good fruit (quality). It is always almost crunchy even when it is bruised due to insects attacking it. How can I get a good harvest? Will fertilizing it work? Will wrapping it with brown paper bags work?

This problem may be related to the timing of harvest, since under- and over-ripe soursop fruits have poorer flavor and texture quality. Soursops also may need to ripen after harvest for optimum flavor, as described in the following article: https://www.hort.purdue.edu/newcrop/morton/soursop.html
