Raised beds and garlic for zone 2/3
We're planning to start some garlic this fall in our Anchorage, Alaska garden. We tried last year, but put off planting until too late and, before we knew it, ground freeze. Nonetheless our spring-planted bulbs seem to like our planting location.
We're looking for advice from anyone growing garlic in colder climates (zone 2/3). In our neighborhood we have winters with colder temps (teens to zeros F, typically, with stretches of 10s below with more rare, brief periods to 30s below at night). Past few winters have been more mild though. Spring and early summer are very dry and fairly warm, but mid-late summer and fall are cool with prolonged stretches of drippy wet weather.
We use 8" raised beds for many of our annual vegetables and herbs, to keep soil warm and hold them above the mucky wet soil. However, I'm concerned that raised beds will expose overwintering garlic to cold that will kill it. Has anyone grown garlic in raised beds in the cold? Suggestions/alternatives?
I'd also like to hear what varieties anyone has had success with in this type of climate.
