Rose of Sharon (Hibiscus syriacus) is a popular deciduous shrub, cherished for its vibrant, late-summer blooms. This hardy hibiscus is known for its low maintenance and adaptability, making it a common landscape feature. However, a frequent concern for gardeners is potential damage from local rabbit populations.
Rabbit Feeding Habits with Rose of Sharon
While Rose of Sharon is not typically a rabbit’s first choice for food, these animals will browse on it, especially when other, more preferred food sources are scarce. Young, newly planted Rose of Sharon shrubs are particularly vulnerable due to their tender growth. Rabbits often target new shoots and young leaves. In colder months, when green vegetation is limited, rabbits may also gnaw on the bark of Rose of Sharon, particularly on younger branches.
Damage is most commonly observed on the lower portions of the plant, typically within a rabbit’s reach, which is about three feet from the ground. The clean, angled cuts on stems can indicate rabbit activity, distinguishing it from deer damage, which tends to be more ragged. While established, larger Rose of Sharon shrubs may tolerate some browsing, continuous defoliation of new growth can weaken the plant and hinder its development.
Protecting Your Rose of Sharon from Rabbits
Implementing physical barriers is an effective method to safeguard Rose of Sharon from rabbit damage. Installing a fence around individual plants or garden beds can prevent access. This fencing should be at least 24 to 36 inches tall, as rabbits can jump, and it should be buried 4 to 6 inches deep to deter burrowing underneath. Chicken wire or welded wire with small openings (1 inch or less) works well for this purpose. For young or newly planted shrubs, individual tree guards or wire cylinders can provide localized protection.
Commercial repellents offer another layer of defense by making the plants unappealing through taste or smell. Many effective repellents contain ingredients such as putrefied egg solids, garlic, or predator urine, which rabbits find repulsive. These products typically require reapplication after rain, heavy dew, or new plant growth to maintain effectiveness.
Some gardeners also use strong-smelling substances like Irish Spring soap or a mixture of water and hot sauce as homemade deterrents. Removing nearby brush piles or tall weeds can reduce hiding spots for rabbits, making the area less attractive to them. Regular inspection of your Rose of Sharon for early signs of browsing can help you intervene before significant damage occurs.
Is Rose of Sharon Safe for Rabbits?
Rose of Sharon (Hibiscus syriacus) is generally considered non-toxic to rabbits. While it is not a recommended primary food source, and consumption in very large quantities might lead to mild digestive upset, it is not listed as highly poisonous like some other plants. The plant is a member of the Malvaceae family, which includes other hibiscus varieties. However, allowing continuous browsing can negatively impact the health and vigor of the Rose of Sharon plant itself.
