|I have an avocado tree, several years old and about 2 or 3 feet tall, in a 5-gallon pot outside. Almost all of the leaves are brown and crumbling on the edges, reaching well into the leaf, so that the only healthy leaf tissue is a little leaf-shaped patch about the size of my thumb. What's probably wrong, and what can I do to fix it? |
|Your tree is suffering from either drought stress or fertilizer burn. A plant that wants to be a tree will quickly exhibit drought stress in a container. This can show up as tip and margin browning of the leaves. Excess fertilizing (salt buildup) can burn roots and result in burning of leaf margins as well. |
Hope this helps!
