Kalanchoe plants, celebrated for their vibrant, long-lasting flowers and distinct succulent leaves, bring a burst of color to gardens and indoor spaces alike. Gardeners often wonder if these plants are susceptible to browsing by deer.
Kalanchoe’s Deer Resistance
Kalanchoe plants are generally considered deer-resistant. This resistance stems from several characteristics that make the plants unappealing to these animals. Their thick, fleshy leaves have a texture that deer find unpalatable.
The primary reason for Kalanchoe’s deer resistance is the presence of specific chemical compounds, known as bufadienolides. These compounds give the plants a bitter taste and can be mildly toxic, deterring deer from consuming them. While deer may sample a plant out of curiosity, the unpleasant taste and potential for digestive upset usually lead them to seek other food sources.
No plant is entirely deer-proof. In situations where food is scarce due to drought, harsh winters, or high deer populations, deer may browse plants they would normally avoid, including Kalanchoe. This behavior is a survival mechanism, as hungry deer become less selective about their diet. Kalanchoe remains a less preferred option.
Protecting Kalanchoe from Deer
Even with Kalanchoe’s natural resistance, gardeners may still encounter occasional deer browsing, requiring protective measures. Physical barriers prevent deer from accessing plants. Fencing, whether a permanent structure or temporary netting, can deter deer, though it often needs to be at least 7 to 8 feet tall. Netting can also be draped over individual plants.
Deer repellents provide another layer of defense by making plants unappealing through scent or taste. Scent-based repellents utilize odors that deer dislike, such as garlic, hot pepper, mint, or a rotten egg mixture. Taste-based repellents are applied directly to the plant foliage, making it bitter or spicy to deter browsing. These repellents require reapplication, especially after rain.
Strategic planting can also help protect Kalanchoe and other vulnerable plants. Placing Kalanchoe closer to structures or in areas with frequent human activity can make deer hesitant to approach. Additionally, surrounding Kalanchoe with other highly deer-resistant plants that have strong scents, fuzzy leaves, or bitter tastes can create a natural buffer. These combined approaches can significantly reduce the likelihood of deer damage in your garden.
