Things I've learned about avocados

So, some important things I've learned about planting and caring for an avocado tree.

• They NEED fast-draining soil. Avocado trees really suffer in heavy soils and are more susceptible to root rot in wet conditions.
• They are sensitive to salts in their water supply. In SoCal we have alkaline and salty tap water, which burns the tips of leaves as the salts build up. (It also raises the pH, when the tree prefers slightly acidic soil.) Deep waterings can help flush salts from the soil. Using gypsum powder helps bind the salts so they stay out of the tree.
• In the wild, baby avocado plants grow up under the shade of larger trees, and because of this get sunburned easily when left in the sun at a young age. They can be painted with white interior latex paint diluted 50% with water to protect against sun damage.
• To help keep the soil from getting water logged, it is recommended to plant avocados on mounds. 
• Trees appreciate heavy mulching, 3-6inches recommended to provide nutrients to the shallow feeder roots and protect them from sun damage.
