I seem to have a growing surplus of used coffee grounds and egg shells. Over the years I have been throwing whatever I had into the surrounding dirt of my pomegranate trees. This year's harvest of pomegranates have introduced alot of fruits that have split open. As a result a black, fuzzy mold would develop in the inside of some of the pomegranates. Could the splitting be due to an excess amount of spent coffee grounds and egg shells I regularly use as fertilizer?
