The Q&A Archives: lime tree not producing limes

Question: I have a lime tree that produced many limes for the first 2 years we planted it but now it is producing none (2 more years). I fertilize it with citrus-specific fertilizer. It is also very yellow in the leaves. It is on the south side (warm) in the San Francisco bay area. It is watered regularly through a drip system.

Answer: Feeding with a citrus specific food should supply all the necessary nutrients. If both new and old leaves are yellowing and dropping off at a disturbing rate and there hasn't been an extreme heat wave or a freezing cold snap, your tree may be suffering from some kind of root problem, or it simply can be a sign of water stress. As a rule, citrus trees need more heat than is generally found in the Bay Area. While the trees will grow in your area, they won't reliably bloom and set fruit, except when the winters and summers are especially warm. Watch for flowering this year. If there are no flowers, the tree is not getting the heat it requires; if there are flowers and no fruit, wind or rain or lack of insect activity for pollination is usually the cause. Wish I had more information to share with you.
