Snow can be a beautiful sight, but it poses challenges for certain plants in your garden. Tender perennials, young trees, and evergreen shrubs often need extra protection from snow to survive the winter months. Understanding which plants are most vulnerable and how to safeguard them ensures your garden thrives year-round.
Which Plants Need the Most Protection from Snow?
1. Tender Perennials
Tender perennials, such as dahlias and cannas, are particularly susceptible to cold and snow. These plants, which thrive in warmer climates, require careful protection to withstand winter conditions.
- Dahlias: Store tubers indoors after the first frost.
- Cannas: Mulch heavily or dig up and store rhizomes.
- Begonias: Lift and store tubers in a cool, dry place.
2. Young Trees
Young trees are vulnerable to snow damage due to their flexible branches and developing root systems. Heavy snow can cause branches to break or bend, leading to long-term structural issues.
- Fruit Trees: Wrap trunks with burlap to prevent cracking.
- Ornamental Trees: Stake young trees to provide support.
- Conifers: Gently brush off snow to prevent limb breakage.
3. Evergreen Shrubs
Evergreen shrubs, such as boxwoods and rhododendrons, need protection from both snow and harsh winter winds. These conditions can cause desiccation, where plants lose moisture faster than they can absorb it.
- Boxwoods: Use burlap screens to shield from wind.
- Rhododendrons: Apply an anti-desiccant spray.
- Hollies: Mulch around the base to protect roots.
How to Protect Plants from Snow
Using Mulch and Covers
Mulching is an effective way to insulate plant roots and maintain soil temperature. For more delicate plants, consider using covers or cloches.
- Mulch: Apply a 2-4 inch layer of organic mulch around the base.
- Cloches: Use plastic or glass cloches to protect tender plants.
- Fleece Covers: Drape over shrubs to shield from snow and wind.
Building Windbreaks
Windbreaks are essential for protecting plants from harsh winter winds that accompany snow. These structures can be temporary or permanent.
- Burlap Screens: Install around sensitive plants.
- Hedges: Plant evergreen hedges for natural wind protection.
- Fences: Use wooden or plastic fencing as a barrier.
Pruning and Maintenance
Regular pruning helps plants withstand snow by reducing the weight on branches and improving overall structure.
- Prune in Fall: Remove dead or weak branches.
- Shape Shrubs: Maintain a compact form to minimize snow accumulation.
- Inspect Regularly: Check for damage after snowfalls and take corrective action.
Practical Examples and Case Studies
Case Study: Protecting a Young Orchard
In a small orchard in Vermont, young apple trees faced severe winter conditions. The orchard owner used a combination of mulching, trunk wrapping, and stake supports to protect the trees. As a result, the trees survived the winter with minimal damage and produced a healthy crop the following year.
Example: Evergreen Shrub Protection
A homeowner in Michigan used burlap screens and anti-desiccant sprays to protect her rhododendrons and boxwoods. Despite heavy snowfall, the shrubs remained healthy and vibrant, providing year-round greenery.
People Also Ask
How do I protect my garden from snow damage?
To protect your garden from snow damage, use mulch to insulate roots, cover sensitive plants with cloches or fleece, and build windbreaks to shield against harsh winds. Regular pruning also helps minimize snow accumulation on branches.
What are the best materials for plant covers?
The best materials for plant covers include burlap, horticultural fleece, and plastic cloches. These materials provide insulation while allowing air circulation, preventing moisture buildup and mold.
Can snow actually benefit some plants?
Yes, snow can benefit some plants by acting as an insulating blanket that protects the soil and roots from extreme cold. It also provides moisture as it melts, which is essential for plant growth in spring.
Should I remove snow from my plants?
Yes, gently remove snow from plants, especially from the branches of young trees and evergreen shrubs, to prevent breakage. Use a soft broom to brush off snow, being careful not to damage the plant.
When should I start preparing my garden for winter?
Start preparing your garden for winter in late fall, before the first frost. This includes mulching, pruning, and setting up protective covers to ensure plants are ready for snow and cold temperatures.
Summary
Protecting your garden from snow involves understanding which plants are most vulnerable and taking proactive measures to safeguard them. By using mulching, windbreaks, and proper maintenance, you can ensure your tender perennials, young trees, and evergreen shrubs survive the winter months.
