Lemon tree is losing leaves, no fruit
I have a lemon tree that I have had for almost 2 years. Living in an area that occasionally gets freezing temperatures, I move it indoors in the late fall. It will be doing fine, but then leaves start to fall. Last spring, after a winter of losing leaves, I pruned it. It grew like crazy, put on blooms, and little nubs of fruit. But then slowly, the nubs began to dry up and fall off. This last fall, the same thing happened with leaves falling. I do keep it watered, fertilized , and in a sunny spot. Some ole time gardener told me bone meal. Any advice would help. Thanks so much. Jean Davidson email@example.com

Bone meal can help, but if the growing season is not long enough, and you have to bring it indoors, then it will not fruit unless you have supplemental light. This is also why the leaves fall off. They need at least 200 watts of light to be able to produce indoors. I recommend LED because it is less hot, and consumes much less energy then Gas lit bulbs.
