The Q&A Archives: Citrus trees

Question: Both my Lemon and Navel Orange trees have lots of curling leaves and some have small brown spots. What does this mean and how is it treated?? I water trees thoroughly with a drip system every day.

Answer: Terri,

This us most likely due to a foliar disease. There are several that can affect citrus. Take care to not keep the soil too soggy wet but water enough to maintain some soil moisture.

Take some citrus leaves showing the curling and spots to your County Extension Office. They should be able to identify the problem and prescribe an appropriate control.

Thanks for the question. Please stop in again soon.
