May and early June have seen a string of rainy days in New England. With that much-welcome rain, unfortunately, has come an equally unwelcome pest: slugs. Look over the undersides of leaves in your garden (especially low-growing perennials) and, if you see any slugs, assume there are more lurking in the soil or mulch. Skip the cutesy internet-fed slug remedies and go for what works: iron-phosphate-based pellets, available under several brand names in most nurseries. Place them around the base of plants and replenish monthly as long as it keeps raining.
