Garlic may be planted in the spring or fall. I usually plant mine in the fall. Pull it up when many of the leaves have turned brown and dry looking. This happens around June usually.
I do put row covers over the garlic during the winter. I don’t plant it in the spring, because I have so many other crops that I need or want to plant.
Anything that can be grown outdoors during the winter is planted in the fall here on our little acre. Winter wheat is a biggee as is winter rye. Helps the ground, provides wheat berries and or green manure to turn under in spring.
