Yes, rabbits do eat ninebark. Ninebark (Physocarpus opulifolius) is not considered resistant to rabbit browsing, and these common garden visitors can cause significant damage to the shrub, particularly to new plantings.
Understanding Rabbit Browsing Behavior on Ninebark
Rabbits are known to browse on a wide variety of plants, and ninebark, with its accessible foliage and stems, can become a target. Gardeners living in areas with active rabbit populations should be aware that these shrubs are vulnerable. Young, newly installed ninebark shrubs are especially susceptible, as their tender growth and smaller stature make them easy prey for hungry rabbits seeking sustenance. Protecting these plants from browsing is a common recommendation to ensure their establishment and healthy growth.
Effective Strategies for Protecting Ninebark from Rabbits
To safeguard your ninebark shrubs from rabbit damage, especially during their critical establishment phase, implementing protective measures is highly advisable. Proactive steps can prevent irreversible harm and ensure your plants thrive.
Here are some effective strategies:
- Physical Barriers: This is often the most reliable method.
- Wire Fencing Cages: Surround individual shrubs with a sturdy wire mesh cage. The mesh should be small enough (e.g., 1/2-inch or 1-inch hardware cloth) to prevent rabbits from squeezing through. Ensure the cage is tall enough (at least 24-30 inches) to prevent rabbits from reaching over, and bury the bottom few inches of the fence into the ground to deter burrowing.
- Plastic Netting: While less durable than wire, plastic netting can also be used to encircle plants. It should be securely fastened to stakes and extend above the potential browse height of rabbits.
- Repellents: Rabbit repellents can deter browsing, but their effectiveness varies and they often require reapplication, especially after rain or irrigation. Look for products designed for edible plants if you are concerned about chemical exposure.
- Planting Mature Stock: While not always feasible, planting larger, more established ninebark plants can sometimes mean they are less vulnerable to complete defoliation by rabbits compared to small, tender saplings.
- Maintain a Clean Garden: Removing tall weeds or brush near your ninebark can reduce hiding spots for rabbits, making the area less appealing to them.
By implementing these protective measures, you can significantly reduce the risk of rabbits damaging your ninebark shrubs, allowing them to grow into beautiful, mature additions to your landscape.
