First, thanks to all who share their questions and ideas here — I have learned a ton already!
I’m in San Diego in Sunset climate zone 23 / USDA zone 10b. I have clay soil. I’ve been in my home for 3 years and have been trying to improve the looks of a cherimoya tree that has been there for some time. Its fruit varies in size and bumpiness. It’s very tasty when I can get to it before squirrels. It looks like it was previously left on its own with many overlapping branches and dead wood.
The leaves have been looking good since starting to come in around May. I had been watering every 10 days or so. About 3 weeks ago, the leaves started drooping with some turning yellow or brown and dropping.
It has been very hot. I increased watering but am not seeing any improvements. Would you recommend trying even more water? Less? Looking at nutrient issues?
As a bonus, if anyone has any pruning tips I’m all ears. You can see some pretty wild growth since spring and given that I’d like to maintain or reduce the tree size I wonder whether some pruning now or during winter could be beneficial.
