yellow leaves on citrus
Yellow leaves on your citrus tree could be an indication of many different things. It could be that it has outgrown this container and needs repotting or planting in the ground. Does it dry out quickly between waterings? If so, this may be the case. Yellow leaves could also indicate that the plant needs fertilizing. Make sure you use a fertilizer formulated for citrus that includes micronutrients as well as nitrogen, phosphorus and potassium. Another possible cause of yellowing is insect infestation. Check the leaves and stems closely for presence of insects, and treat accordingly.
