No Lemons on My Lemon Tree

Q. My tree has been in the ground for six years and each year I get plenty of new growth, leaves and flowers. The problem is, no lemons at all. I have applied fertilizer and even  miracle grow--no luck. What do you suggest other than removing the tree and starting fresh?

A. The usual reasons for no lemons is either freezing temperatures after they bloom that kill the flowers or small fruit (usually in January or February) or irregular watering that causes trees to stress and drop flowers and fruit before they can mature.
A light freeze will kill flowers and fruit without damaging the tree. If you have been pruning the tree, stop pruning it. Fertilize it once a year in January or February. Put a surface mulch of wood chips around the tree at least 6 feet in diameter and 3 inches deep.
Cover the tree with a sheet or light blanket if temperatures during the winter approach freezing. Put a basin around the tree and fill the basin with water each time you irrigate. Avoid watering daily. Skip at least one day between irrigations.
