I have several orange and grapefruit trees in containers, and they look healthy except that their leaves are starting to look yellowish -- not the deep green they once were. (The leaves aren't falling off, however.) What is causing this, and what can I do?

Citrus are heavy feeders and will quickly use up nutrients in a container situation, so I suspect your trees simply need some supplemental nutrients. If you can find a citrus fertilizer at your local nursery, use that. Otherwise, any all-purpose balanced fertilizer such as 10-10-10 or an organic equivalent will be fine. Dilute fertilizer according to package directions.
