Tropical Fruit Discussion / Black sapote leaf drop/disease
« on: December 26, 2016, 12:47:31 PM »
Hi,
Several years ago @Ethan gave me a small black sapote. I live in Missouri. The tree is potted and spends the winters in the greenhouse, summers outside. The tree is now 5-6' in height. It started flowering 2 years ago and has borne fruit. Per usual, the tree came inside the greenhouse this past fall. It has a sunny spot and is evenly watered.
Generally for me this tree holds the leaves through the winter and drops leaves the next spring or summer. In the past week, this tree has demonstrated dramatic leaf drop. The leaves are perfectly green, not yellow or brown. On closer inspection, there appears to me to be some dieback. Some lower branches are completely black, and some smaller secondary branches have also turned black and died.
The roots look OK. I spray with Neem every couple of weeks in the winter. I hit it with a fungicide today. This is not normal based on my experience with the tree. Thoughts?
