Lemon tree not producing
I purchased a lemon tree from a catalog about 7 years ago. It was rather small (less than 12 inches), but it has now grown to about 2.5 feet. The leaves are not dark green and it has never bloomed. Any ideas on what I should be doing? I have heard that I need to "wound" the tree to make it think it is dying and must then produce fruit. Any truth to something like that? Thanks for any assistance!!
