The Problem with Deer in Gardens

Do Coffee Grounds Keep Deer Away? What You Need to Know

Deer are beautiful creatures that charm rural areas but can become a gardener’s worst nightmare. North America’s largest garden pest, deer, feasts on vegetable gardens, flowerbeds, and shrubs, wreaking havoc in the garden. Despite using deer repellants such as egg-based products, dried blood, garlic, or soaps, a fence around the garden is the most effective technique for deterring deer. However, even with a fence, some garden plants might still fall victim to male deer’s fraying or thrashing.

Gardeners experiencing consistent damage to certain plants have a garden with moderate pressure, which can be attributed to the increased habituation of deer to human activity. To prevent this, gardeners should not feed deer, as it changes their behavior towards foraging near homes and in gardens, leading to considerable damage to plants. While hunting may not be an option in rural subdivisions with restrictions on firearm use or deer protection laws, deer-proofing helps keep gardeners’ sacred spaces out of these beautiful animals’ reach.
