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.
Gardening in Idaho
Idaho has a semi-arid continental climate. Southern valleys are Zone 6-7 with hot dry summers; northern regions and mountains are colder. Excellent for root vegetables and cool crops.
