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 Ontario
Ontario spans several climate zones. Northern Ontario is Zone 3-4 with short seasons; southern Ontario is Zone 5-7 with long productive seasons. The Niagara Peninsula is one of Canada's premier fruit-growing regions.
