I have a question regarding an orange plant that I have in my garden. It is planted in the ground (i.e., it is not in a pot). It is about three years old. The plant has not grown at all in these three years. There are very fe w leaves on it. Often the leaves turn yellowish, curl up and fall down. Dur ing summer (as in now), when other fruit plants in my garden grow and becom e full of leaves, it has barely few. It has now started to shed even leaves that are green.
I initially suspected some insects behind the problem. It could still be tr ue, but that may not be the only problem.
I wonder if anyone can identify any cure for this problem.
Thanks very much in advance.
