About Avocado
Avocados need frost-free conditions year-round and take 3-5 years to bear fruit from seed.
Outdoors only in Zone 9b-11. In colder zones grow dwarf varieties in large containers indoors near a sunny window — they will not produce fruit reliably indoors but make beautiful houseplants. Very frost-sensitive.
