Grow your own avocados
Instead of sprouting an avocado pit like a preschool project ― the resulting harvest, if any, will take at least 5 years and
may not taste very good in the end ― buy a young tree.
You can grow a Hass in Sunset climate zones 16, 17, 19, 21, 23, and 24; for zone explanations and complete growing instructions, see the Sunset Western Garden Book or sunset.com/climatezones.
Along with an appropriate climate, give your tree enough space (canopies can spread 30 feet); excellent drainage; and enough water so that soil is moist but not wet.
