sweet lemon tree and avocado tree
In early June my lemon tree had pollen but then I noticed that all of the pollen had dropped. However, I did get two small lemons growing but for some reason they turned brown. What is going on? I also deep water every three days, letting the soil dry out.
I also have an avocado tree, about 11 feet high, and in June it started dropping a lot of small avocados with a lot of leaf drop too. The leaves turn yellow to brown then drop. I water the avocado tree every three days, rotating the hose every ten minutes around the tree.
