The Q&A Archives: avacados

Question: How do I grow avacado trees here in California.

Answer: You can successfully grow an avocado tree if you choose the right type. Avocados do well in the mild-winter areas of California, Florida and Hawaii. Some hardier varieties can be grown in the cooler parts of northern and inland California and along the Gulf Coast. The northern limits in California are approximately Cape Mendocino and Red Bluff. Mexican types are native to dry subtropical plateaus and thrive in a Mediterranean climate. They are hardy 24 - 19? F. Avocados need some protection from high winds which may break the branches. There are dwarf forms of avocados suitable for growing in containers. Avocado trees like loose, decomposed granite or sandy loam best. They will not survive in locations with poor drainage. Here are some of the hardier types of avocados: Bacon Origin James Bacon, Buena Park, 1954. Hybrid. Tree broad, productive. Fruit small to medium, to 12 oz., round-ovoid, smooth green.
