Avocado trees are easy to care for, their biggest demand being frequent watering. When you’re selecting a planting site for your avocado tree, you’ll need to consider the tree’s age. Young avocado trees need a protected, shaded location for the first two to three years. After that, the trees need plenty of sunlight exposure in order to bear fruit. You can grow your avocado tree in a container for the first few years and place the tree beneath a larger tree or on the north side of your house, and then transplant the tree into a sunny location in your yard. You can also erect a removable shade structure over the young tree for the first three years.
Water your avocado tree two or three times per week during the spring through the fall. Allow the top 1 or 2 inches of soil around the tree to dry out between waterings. Avoid watering the avocado tree in winter to prevent root rot.
Feed your avocado tree annually in the spring after it’s about 2 years old, using a well-balanced fertilizer made for citrus trees or a combination top-dressing of organic compost and used coffee grounds. If you’re using the commercial fertilizer, follow the dosage directions on the package.
Provide additional protection against hot sunlight by painting the young avocado tree’s trunk with tree paint or a diluted water-based paint. Cover the entire trunk, from the ground to the lowest branches.
Protect your young avocado trees from near-freezing temperatures and frost, especially during the first year after planting. Cover your avocado tree with a blanket or bed sheet when frost threatens.
