How to Treat Yellow Leaves on an Avocado Tree
- 1). Diagnose your problem. Are the leaves of the lower branches of the tree getting yellow and dropping off? Are leaves all over the avocado tree growing yellow, while the veins and tips of the leaves stay green? Having specific details about your avocado tree will help you treat it correctly and efficiently.
- 2). Improve the growing conditions of your avocado tree for yellowing only on the lower branches. This is a sign of too much water and a lack of sunlight. Restrict watering to allow the soil around the tree to dry marginally. If you can move the tree to a sunnier location, do so. If you can't, consider pruning the vegetation around the tree to allow for more sun exposure.
- 3). Supplement the growing conditions of your avocado tree for yellowing across the entire tree. This is a sign of iron deficiency in the tree. Start fertilizing the tree with a 10-10-10 fertilizer, or purchase and use iron supplements. Always follow manufacturer directions when you're mixing and using fertilizers or supplements. Sprinkle the fertilizer or supplement into the soil around the tree, rather than onto the tree or its roots.
