Transplanted arborvitae hedges can add beauty and privacy to your landscape, but they require proper winter care to survive and thrive through the cold months. Winterizing your arborvitae ensures they stay healthy, retain their shape, and resist winter damage.
Understanding the Needs of Transplanted Arborvitae
Arborvitae, also known as Thuja, are popular evergreen shrubs that are relatively hardy. However, transplanted arborvitae are more vulnerable during their first winter after planting. Proper winterization helps protect their roots and foliage from harsh weather conditions.
Steps to Winterize Your Arborvitae Hedge
1. Water Thoroughly Before the First Freeze
Ensure your arborvitae receives adequate water before the ground freezes. Well-hydrated plants are better equipped to withstand winter stress. Water deeply to moisten the soil to a depth of at least 12 inches.
2. Apply Mulch Around the Base
Apply a 2-3 inch layer of mulch, such as wood chips or shredded bark, around the base of the hedge. Mulch insulates the roots, maintains soil moisture, and prevents frost heaving.
3. Wrap the Hedge for Extra Protection
Use burlap or frost cloth to wrap young or newly transplanted arborvitae. Secure the wrapping with string or clips, ensuring it covers the entire plant without constricting growth. This helps shield against windburn, heavy snow, and ice damage.
4. Prune Excess Growth
Remove any dead or damaged branches to reduce stress on the plant. Avoid heavy pruning late in the season, as this can stimulate new growth vulnerable to winter damage.
Additional Tips for Successful Winterization
- Monitor weather forecasts and take action before a heavy snowstorm or freeze.
- Avoid fertilizing late in the season, which can encourage tender new growth vulnerable to cold.
- Check regularly for signs of winter stress, such as browning or needle drop, and address issues promptly.
- Ensure proper spacing between plants to allow good air circulation, reducing the risk of disease.
By following these steps, you can help your transplanted arborvitae hedge withstand winter conditions and emerge healthy in the spring. Proper winter care is an investment in the longevity and beauty of your landscape.
