Morning glory vines, with their vibrant, trumpet-shaped blooms and vigorous climbing habit, are a popular choice for gardeners. These fast-growing plants quickly cover fences, trellises, and arbors, creating a lush display. Gardeners in areas with wildlife often wonder about protecting their plants from browsing animals, particularly deer.
Do Deer Eat Morning Glory Vines
Deer do eat morning glory vines, though these plants are generally not their most preferred food source. While some reports suggest morning glories are rarely damaged, others indicate deer will browse on their tender leaves and vines. Deer are opportunistic feeders, meaning their diet varies widely based on what is available. If more palatable food sources are scarce, such as during drought or harsh winter conditions, deer are more likely to browse on plants they might otherwise ignore.
Why Deer Might Avoid Morning Glories
Morning glories possess characteristics that make them less appealing to deer. Their seeds and sometimes foliage contain compounds like alkaloids, which can be unpalatable or mildly toxic to deer. This chemical deterrence acts as a natural defense. While deer often avoid plants with fibrous textures or fuzzy leaves, the chemical compounds in morning glories contribute to their general resistance.
Identifying Deer Damage
To identify deer damage on morning glory vines, look for specific indicators. Deer lack upper incisors, so they tear plant material rather than making clean cuts, resulting in a ragged or torn appearance on leaves and stems. Deer browsing damage can occur on plants up to six feet high. In contrast, rabbits make clean, precise cuts closer to the ground. Insect damage typically appears as holes or chewed margins, distinct from deer tearing.
Protecting Your Morning Glory Vines
Several strategies can help protect morning glory vines from deer browsing. Physical barriers, such as fencing or netting, offer a reliable defense. For full protection, fences should be at least 8 feet tall, as deer can easily clear lower obstacles. Alternatively, micro-enclosures around specific plants or garden beds can provide targeted protection.
Deer repellents can also be effective, either store-bought options or homemade mixtures. Repellents often work by emitting strong odors or unpleasant tastes that deter deer. Common homemade repellents include solutions made from eggs, garlic, or hot peppers mixed with water and a sticking agent like dish soap. These repellents require regular reapplication, especially after rain, to maintain their effectiveness.
Companion planting is another method, involving planting morning glories alongside other plants that deer typically avoid due to strong scents, bitter tastes, or unappealing textures, such as lavender, marigolds, or rosemary. Placing these deer-resistant plants around the perimeter of your morning glory planting can create a natural deterrent. Consistent monitoring of deer activity and adapting your protection strategies accordingly will help safeguard your morning glories.
