When winter’s chill sets in, many gardeners wonder which plants need protection from the cold. Tender perennials, young trees, and certain evergreens often require covering to survive harsh winter conditions. Understanding which plants need extra care can help ensure your garden thrives year-round.
What Types of Plants Need Winter Protection?
Which Perennials Need Covering?
Tender perennials are most vulnerable to frost and freezing temperatures. These plants, such as geraniums, dahlias, and cannas, thrive in warmer climates and can suffer damage or death in cold weather. To protect them:
- Cover with mulch or straw to insulate roots.
- Use burlap or frost cloth for above-ground parts.
- Consider digging up and storing in a frost-free place.
How Do Young Trees Benefit from Winter Cover?
Young trees, particularly those under three years old, require protection from winter’s harsh elements. Frost, wind, and sun can damage bark and roots. Protect young trees by:
- Wrapping trunks with tree wrap or burlap.
- Applying a thick layer of mulch around the base.
- Using windbreaks to shield from strong gusts.
Why Do Some Evergreens Need Winter Care?
Certain evergreens, especially those newly planted or in exposed locations, can suffer from winter burn. This occurs when the sun and wind dry out foliage. To prevent this:
- Water deeply before the ground freezes.
- Shield with burlap screens or windbreaks.
- Apply an anti-desiccant spray to reduce moisture loss.
Practical Examples of Plant Protection
Consider the following case studies to better understand how to protect your plants:
-
Dahlias in Northern Climates: In areas with harsh winters, gardeners often dig up dahlia tubers after the first frost and store them in a cool, dry place until spring.
-
Newly Planted Arborvitae: These evergreens are prone to winter burn. Gardeners often wrap them in burlap or use windbreaks to shield them from winter winds.
-
Young Fruit Trees: Wrapping the trunks of young apple or cherry trees can prevent sunscald and frost cracks, ensuring healthy growth in spring.
How to Cover Plants for Winter
What Materials Are Best for Covering Plants?
Choosing the right materials is crucial for effective winter protection. Consider these options:
- Burlap: Ideal for wrapping trees and shrubs; breathable and insulating.
- Frost Cloth: Lightweight and effective for covering perennials and tender plants.
- Mulch: Organic mulches like straw or wood chips provide excellent root insulation.
Can I Use Household Items for Plant Protection?
Yes, many household items can serve as effective plant covers:
- Old Bed Sheets: Useful for covering larger plants or shrubs during unexpected frosts.
- Plastic Containers: Can be used to cover small plants, but ensure they are removed during the day to prevent overheating.
- Cardboard Boxes: Provide temporary protection against frost for small plants.
People Also Ask
How Do I Know If a Plant Needs Winter Cover?
Plants that are not hardy in your zone, newly planted, or have been pruned recently often require protection. Check your area’s USDA hardiness zone and compare it with your plants’ needs.
When Should I Cover My Plants for Winter?
Cover plants before the first hard frost. Monitor weather forecasts and apply protection when nighttime temperatures consistently drop below freezing.
Can I Leave Covers on All Winter?
While some covers like mulch can remain all winter, others, like plastic or fabric, should be removed during warmer days to prevent overheating and allow light exposure.
What Happens If I Don’t Cover My Plants?
Unprotected plants may suffer from frost damage, dehydration, or sunscald. This can lead to stunted growth or death, particularly in tender perennials and young trees.
Are There Alternatives to Covering Plants?
Yes, alternatives include relocating potted plants indoors, using cold frames, or selecting hardy plant varieties suited to your climate.
