Home & garden, state by state
Coastal British Columbia’s mild winters and Vancouver’s average November frost date shape when to plant garlic, which types survive, and how long bulbs store afterward.
Alberta’s cold winters exceed garlic’s chilling requirement, so success depends on planting cloves ahead of the first fall frost and choosing hardneck varieties suited to hard winters.
A frost-date breakdown of when to plant garlic in Arkansas, which cultivars fit the state’s winters, and what the local disease pressure actually is.
Anchorage’s NOAA frost data shows Alaska has ample cold for garlic vernalization, and settles which cultivars, planting week and winter mulch actually work here.
Arizona’s low desert rarely gets enough sustained cold for garlic to divide into cloves, so growers there chill cloves first or choose softneck varieties.
Susanville is a softneck Artichoke garlic with a long shelf life, best suited to gardeners whose winters run mild but still need supplemental chill.
Silver White is a softneck Silverskin garlic that needs six weeks of chill to divide properly, a requirement many mild-winter regions can’t meet without refrigerating cloves first.
Lorz Italian is a mild, long-storing softneck Artichoke garlic that needs real cold to divide, so growers in warm states must chill cloves before planting.
Red Toch is a softneck Artichoke garlic that needs real winter cold to divide into cloves instead of one plain bulb.
Silver Rose is a mild-flavored Silverskin garlic that needs weeks of near-freezing cold to divide, so where you live decides how to plant it.
