I planted strawberries in a small raised bed this weekend, it is now snowing. Do I need to cover my strawberries to protect them from frost or will the snow provide that protection?
No. Snow is a good covering that protect against frost. Snow is made by snow flakes, so there is a lot of air (but also compact, so that such air cannot escape easily) , which insulate the soil.
On my region they say "Snow means bread, frost means hunger".
When there is no snow, you should care much more about frost. A garden tissue is good. Or just leaves (if frost is not extreme and long).
