Why are my lemons yellowing and falling off prematurely?
I live in zone 6b in New York. This year I bought two Improved Meyer Lemons from Monrovia, and have them in containers. They have been outside since the middle of April in a very sunny south-facing spot and watered every few days when dry. IÃ¯Â¿Â½ve fertilized them about every two weeks with some fertilizer I had thatÃ¯Â¿Â½s intended for tomatoes (forget the exact kind), and dried blood fertilizer to boost the nitrogen content. They came with fruit on them already that has not grown at all or fallen off since purchasing. TheyÃ¯Â¿Â½ve been flowering nicely, and IÃ¯Â¿Â½ve been cross-pollinating the two plants. However, once the new fruit gets to about the size of my pinky fingernail, it will turn yellow and eventually fall off, every time. IÃ¯Â¿Â½ve also noticed that a few of the branches are dieing, though the new vegetative growth the plants have experienced has significantly outweighed any dieing branches. So, my question is, how do I get my fruit to stop dieing, so I can get some lemons?
