Ice plants, such as Delosperma and Lampranthus, are popular groundcovers known for their vibrant, daisy-like flowers and drought tolerance. Gardeners often choose these succulents for landscape color and texture. A common question for those in areas with wildlife is their susceptibility to deer browsing.
Ice Plant and Deer Resistance
Ice plants are generally considered deer-resistant. Their succulent, often bitter or fuzzy foliage deters deer. While no plant is entirely deer-proof, ice plants are rarely a preferred food source. Species like Delosperma cooperi and Lampranthus spectabilis are noted for their resistance. This makes them a suitable choice for landscapes with deer, especially when other palatable options are available.
Why Deer Might Browse
Despite their resistance, deer might browse on ice plants under specific circumstances. Extreme hunger, from drought, harsh winters, or overpopulation, can compel deer to eat plants they normally avoid. Young or newly planted ice plants are more vulnerable as they are less established. If ice plants are the only green vegetation available, deer may sample them out of necessity. Curiosity, especially among younger deer, or individual preferences can also lead to occasional browsing.
Protecting Your Ice Plant
If deer browse your ice plants, several strategies can deter them. Physical barriers, like temporary netting or low fencing, can effectively protect new or vulnerable plantings. Commercial deer repellents (taste-based or scent-based) can make plants less appealing. Rotating repellents prevents deer from becoming accustomed to one deterrent.
Strong-smelling companion plants, such as herbs or marigolds, near ice plants can deter deer, as they avoid strongly scented foliage. Providing other desirable food sources elsewhere might divert deer from your ice plants. Regular inspection for browsing signs and prompt action can mitigate damage.
Recognizing Deer Damage
Identifying deer damage involves specific indicators on your ice plants. Deer lack upper incisors, causing tearing rather than clean cuts when they browse. This leaves stems and leaves with ragged or shredded edges. Browsing occurs from ground level up to about six feet high, reflecting their reach.
Physical evidence around plants can also confirm deer activity. Look for heart-shaped hoof prints (usually two to three inches long) in soft soil or mulch. Deer droppings, appearing as small, oval pellets, are another clear sign of their presence. For persistent or extensive damage, trail cameras can confirm the culprits.
