Relocating from the North East USA to Carmel, California is quite a move. Carmel is an extremely beautiful location, and in my estimation a VERY pleasant place to live. Clint Eastwood was a past mayor of Carmel. About your lemon tree question. A lemon tree will retain only the number of fruit that it is capable of bringing to maturity, and will drop all the rest. Maybe more important for you, is the fact that a lemon draws all of the energy that it requires to grow into a nice full size fruit only from the closest 3-4 leaves to the fruit. Therefore, if you desire size, rather than quantity, you can thin the crop to one lemon for every 3 leaves, this will give you the largest size fruit that your tree is capable of producing. - Millet (456-)
