Spiderwort (Tradescantia species) is a perennial with long, strappy leaves and three-petaled flowers in shades of blue, purple, pink, or white. These plants often grow in clumps, adding color to gardens from late spring into midsummer. They are commonly found in woodland gardens, borders, or as indoor plants, growing in a range of light conditions from full sun to partial shade.
Do Deer Eat Spiderwort
Spiderwort is generally considered deer-resistant. While some sources claim it is deer-proof, it is more accurate to consider it resistant rather than completely immune to deer damage. Its foliage is slightly tough, and its stems contain a viscous sap that hardens when cut. This sticky sap, which gives the plant its common name, is unappealing to deer.
Spiderwort may also possess a bitter taste or compounds deer find undesirable. Deer typically prefer plants with tender, succulent foliage and smooth textures. The slightly coarse texture and potential mild toxicity of spiderwort make it less palatable than other readily available vegetation, positioning it lower on their preferred browse list.
Factors Influencing Deer Browsing
Deer, while generally avoiding spiderwort, might still browse on it under specific conditions. A key factor is the availability of preferred food sources; if their usual diet is scarce, deer become less selective. This often occurs during harsh winter months when natural forage is limited, or during prolonged drought periods that reduce plant succulence.
High deer population density can increase browsing pressure on a wider range of plants. Young, tender spiderwort plants might be more susceptible to initial nibbling than mature ones. Deer are also creatures of habit and may sample new additions to a garden out of curiosity. Local conditions and deer habits can influence browsing patterns, demonstrating that resistance is not absolute.
Protecting Your Spiderwort from Deer
Several measures can protect spiderwort from deer browsing. Physical barriers offer the most reliable protection. Fencing, at least 7 to 8 feet high, is highly effective, as deer are capable jumpers. For individual plants or smaller beds, netting or chicken wire can create a protective enclosure. Ensure barriers are securely staked and high enough to prevent deer from reaching over or pushing through.
Deer repellents, commercial or homemade, are another option. Repellents typically work by taste or smell, containing ingredients like rotten eggs, hot pepper, or strong-smelling soaps. These need consistent reapplication, especially after rain or new growth. Companion planting is another strategy; placing spiderwort near plants with strong odors or unappealing textures, such as lavender, rosemary, mint, or lamb’s ear, can help deter deer. Strategic placement closer to human activity or in areas with less deer traffic can also reduce browsing likelihood.
