Unknown White Sapote with black mold?
« on: December 14, 2021, 08:28:21 PM »
Hello everyone,

We just purchased an old house, and it has an old white sapote tree in the back yard. The tree is about 30-40 years old, but it is only 15-18 ft tall.
So I assume it is a dwarf variety. It is not Suebelle, because I have a Suebelle, the leaves shape is different, and Suebelle's leaves are fuzzy on the backsides.

Recently after a rainy day, the tree blooms and now has clusters of small fruitlets (see picture). I am very excited to try the fruit, and want to improve the tree's health so it will hold all the fruits to maturity.

The previous owner never take care of this tree, it was never watered, and surrounded by big clump of birds of paradise (I will get rid of them).
The leaves of this white sapote are full of black spots that look like black mold. Please see the pictures.
Should I spray the leaves with copper mixed? Should I fertilize the tree so it will get stronger and can fight the disease by itself?

Any input will be highly appreciated!
