I purchased my Meyer lemon tree in the spring. It is about 2 feet tall and resembles a bush. It has produced 4 lemons, but I have not picked them because I heard (don't know where) that you should not pick the first crop, but let them drop to the ground and deteriorate, that it helps the soil for future lemon bearing of the tree. Is there any truth to this? Also, should I prune the tree after the lemons drop, or should I wait until spring. It is planted in my yard. Thanks for your help.
