Avocado Trees

Question

My avocado tree is planted in a pot and sits in my south window all winter and summers outside. My problem is the leaves are turning kind of yellow. I water it well and it has drainage too. It is 3 + years old and about 3 feet tall.

Answer 1

When the veins are greener than the leaf, it means your plant has iron chlorosis. That can be caused by a lack of proper fertilizer, or the pH is off, preventing absorption. Compacted or clay soil can also prevent iron absorption. Here is more:
