Goodbye to snails: rake and rake the beds, then they freeze to death. Rakes and rakes are every gardener's best allies.
By loosening the soil, hiding places for the snails are significantly reduced. The area around the bed should also be cleared of any objects lying around, such as stones or wooden boards. Snails also like to find shelter here and use these hiding places as a starting point for their nightly forays through the bed. Overall, it's worth planning some time in March for thorough garden care.
