I have more slugs than flowers and have been unable to get rid of my slug problem. Formerly the manager of interpretation and plant records at The New York Botanical Garden, Bruce is an expert on a wide range of indoor and outdoor plants, insects, and pests. Melanie Menachem-Riggs is a garden designer and lecturer with a degree in horticulture and botany. She works on residential landscapes using garden structures and plants, including perennials, annuals, herbs, vines, and shrubs to create interest and enhance flowering in the garden.
Slugs chew holes in leaves and flowers.
They leave a silvery trail behind them on the soil and plant. Slugs need a moist environment all the time to survive. They are active at night and hide in damp places during the day. Inspect the garden for slugs at night with a flashlight. During the day, you can find them hiding under boards, slates, lower leaves, and other damp places.
