Arborvitae, also known as Thuja, is a popular evergreen shrub used for privacy screens and landscaping. However, in areas with high deer populations, growing arborvitae can be challenging as deer tend to browse on these plants, damaging or destroying them. This article provides effective strategies to successfully grow arborvitae in deer-prone areas.
Understanding Deer Behavior and Arborvitae
Deer are herbivores that feed on a variety of plants, especially during winter when other food sources are scarce. They are particularly attracted to the tender foliage of young arborvitae and can cause significant damage. Knowing their feeding habits helps in planning effective deer-proofing measures.
Strategies for Protecting Arborvitae from Deer
- Choose Deer-Resistant Varieties: Some arborvitae cultivars are less appealing to deer. For example, ‘Green Giant’ and ‘Emerald Green’ are known for their relative deer resistance.
- Plant in Strategic Locations: Plant arborvitae in areas less accessible or less attractive to deer, such as near human activity zones or in well-lit spots.
- Use Physical Barriers: Fencing is one of the most effective methods. A fence at least 8 feet tall can deter most deer from entering the area.
- Apply Deer Repellents: Commercial repellents containing garlic, putrescent egg, or predator urine can be sprayed on plants to discourage deer.
- Install Motion-Activated Devices: Devices such as sprinklers or lights activated by motion can startle deer and keep them away.
Planting and Maintenance Tips
Proper planting and maintenance can help arborvitae withstand deer browsing and grow healthy in challenging environments.
- Plant at the Right Time: Early spring or fall are ideal planting times when deer activity is lower.
- Maintain Plant Health: Healthy, vigorous plants are more resistant to damage. Ensure proper watering, mulching, and fertilization.
- Prune Regularly: Remove damaged or overgrown branches to promote strong growth and reduce attractiveness to deer.
- Use Protective Covers: Temporary tree wraps or fencing around individual plants can protect young arborvitae during the most vulnerable periods.
Additional Tips for Success
Growing arborvitae in deer-prone areas requires persistence and a combination of strategies. Monitoring deer activity and adjusting your approach as needed can improve success rates. Combining physical barriers, repellents, and selecting resistant varieties offers the best protection for your arborvitae.
