20 yr old dwarf Meyer lemon problems (pix)
Our little dwarf Meyer lemon tree has been a workhorse and flourishing for a good many years. We get lemons almost year round.
Lately, for the past month, our lemons look like this. Some of the leaves are yellow, and we have no pests that we can see on the leaves or the undersides. What could be the problem???? Is it dying after 20 years??? Thanks for any input!
