The Q&A Archives: citrus trees

Question: My orange tree is in full bloum but a lot of leaves started to become yellow and curl. Is it a problem? What do I need to do? This is my first year having a citrus garden. Thank you, Ludmila

Answer: Although citrus trees are evergreen, they do lose some of their oldest leaves - those toward the center of the plant. The lost leaves will be replaced in a few weeks. So, if only the oldest leaves are yellowing, it is normal. If new leaves are yellowing it indicates a need for fertilizer (and possibly iron). Apply a citrus food in amounts as recommended on the fertilizer label. Hope you have a great harvest!
