Skimmia is a popular evergreen shrub valued for its vibrant berries and fragrant flowers. However, like many plants, it requires proper winter protection to survive cold temperatures and harsh weather conditions. Preparing your Skimmia for winter ensures it remains healthy and continues to thrive year after year.
Understanding Skimmia’s Cold Tolerance
Skimmia japonica, the most common variety, is generally hardy in USDA zones 7 to 8. It can tolerate some cold but may suffer damage in prolonged freezing temperatures. Knowing your local climate helps determine the level of winter protection your Skimmia needs.
Preparing Your Skimmia for Winter
Proper preparation involves several steps to shield your Skimmia from cold stress. These include site selection, mulching, watering, and covering techniques. Starting early in the fall ensures your plant is well-prepared for the winter months.
Site Selection and Placement
Plant Skimmia in a sheltered location away from harsh winter winds and frost pockets. An east or south-facing wall provides some protection from cold winds and helps retain warmth. Avoid low-lying areas where cold air can settle.
Mulching
Apply a thick layer of organic mulch, such as straw, pine bark, or compost, around the base of the plant. Mulching insulates the roots, retains soil moisture, and prevents temperature fluctuations that can damage roots during winter.
Watering Before Frost
Ensure your Skimmia is well-watered before the first hard frost. Moist soil retains heat better than dry soil, reducing the risk of root damage during cold spells. Avoid overwatering, which can lead to root rot.
Protective Coverings and Techniques
If your area experiences severe cold, additional protection may be necessary. Covering your Skimmia with suitable materials can prevent frost damage and desiccation.
Using Cloth or Burlap
Wrap the plant with horticultural fleece, burlap, or frost cloth. Secure the covering at the base to trap heat and prevent cold air from reaching the foliage. Remove the covering during milder winter days to prevent moisture buildup.
Creating a Windbreak
Install a temporary windbreak using a wooden frame or lattice covered with fabric. This reduces wind chill and prevents desiccation of the leaves.
Additional Tips for Winter Care
Regular monitoring and maintenance help ensure your Skimmia survives winter intact. Keep an eye out for signs of stress or damage and take prompt action if needed.
Pruning
Prune any damaged or dead branches in late fall. Avoid heavy pruning in late winter, as it can stimulate new growth that is vulnerable to cold damage.
Monitoring for Pests and Diseases
Winter can weaken plants, making them susceptible to pests and diseases. Remove any infected foliage and ensure good air circulation around the plant.
Conclusion
With proper planning and care, your Skimmia can withstand even the coldest winters. Protecting the plant’s roots, covering the foliage, and choosing a suitable location are key steps to ensure its health and beauty come springtime.
