If they need moving, you can do so. IF you can scoop up soil with roots, they will transplant better. But even root-bare, they will be OK. Don't expect them to grow very much though, unless you live in a really cool climate. Once the soil begins to warm up, this signals the garlic to begin dormancy, and they will start leaf-yellowing, beginning with the lower leaves first. Once the leaves begin to die, the garlic bulb will be at/near its full size. I pull mine when 1/2 - 2/3 of the lower leaves have yellowed/dried. This usually occurs here in NE Mississippi around the middle of May. Ken
