Kalanchoe, a popular succulent, is celebrated for its vibrant, long-lasting flowers and straightforward care requirements. For gardeners, especially those in areas frequented by wildlife, a common consideration is whether these attractive plants can withstand browsing by deer.
Kalanchoe and Deer Resistance
Kalanchoe plants are generally considered deer resistant. While no plant is entirely deer-proof, Kalanchoe is not typically a preferred food source for deer. Compared to many other common garden plants, Kalanchoe exhibits a high level of resistance to deer browsing.
Even with their resistance, deer might occasionally browse Kalanchoe, particularly under specific circumstances. For instance, in areas with high deer populations or during periods of extreme hunger when other food sources are scarce, deer may be less selective. Young or newly planted Kalanchoe might also be more vulnerable as they establish themselves.
What Makes Kalanchoe Deer Resistant
Several inherent characteristics contribute to Kalanchoe’s natural resistance to deer. Many varieties possess a bitter taste or an unpleasant odor that deters deer from consuming them. Deer rely heavily on their sense of smell to find food, and strong, unappealing scents can act as a natural barrier.
Beyond taste and odor, the texture of Kalanchoe leaves can also play a role. Some varieties, like the ‘Panda Plant’ (Kalanchoe tomentosa), have thick, succulent, or fuzzy leaves that are not appealing to deer. Deer generally prefer plants with smooth, tender foliage, making the unique textures of Kalanchoe less desirable for browsing.
Furthermore, Kalanchoe contains compounds called bufadienolides, which can cause mild digestive upset in animals if consumed in large quantities. While Kalanchoe is not severely toxic in small amounts, this mild unpalatability discourages deer from making it a regular part of their diet.
Maximizing Kalanchoe’s Deer Resistance
While Kalanchoe is naturally deer resistant, gardeners can implement strategies to further protect their plants in deer-prone environments. Strategic placement can be effective; planting Kalanchoe closer to your home or in areas with more human activity may reduce deer visits. Placing Kalanchoe near other plants that deer find unappealing can also create a less inviting zone.
Companion planting involves pairing Kalanchoe with other highly deer-resistant plants to create a formidable barrier. Plants with strong scents like lavender, sage, or ornamental grasses can deter deer when interplanted with less resistant varieties.
Protecting young or newly planted Kalanchoe is important during their establishment phase. New plantings can be more vulnerable to browsing. Temporary physical barriers, such as netting or wire cages, can shield young plants until they are more mature. Monitoring deer behavior also helps tailor protection methods.
