Protecting Evergreen Shrubs in December: Essential Winter Care Tips for a Thriving Garden
Introduction
Evergreen shrubs bring structure, color, and life to the garden all year round, even when other plants have lost their leaves. However, the harsh winter months, especially in December, can be challenging for these plants. Cold winds, heavy snow, and dry conditions can all stress evergreen shrubs, leading to browning, breakage, and even death. Proper care and protection during winter ensure that your evergreen shrubs remain healthy and vibrant, ready to continue adding beauty to your garden. This guide will explain why protecting evergreen shrubs in December is essential, how to do it effectively, and answer common questions to help you maintain a thriving garden throughout winter.
Why Protecting Evergreen Shrubs in December Is Important
- Prevent winter burn: Cold, dry winds can strip moisture from evergreen leaves and needles, causing browning, known as winter burn. Protecting shrubs from these conditions helps them retain moisture and stay green.
- Avoid breakage from snow and ice: Heavy snow and ice can weigh down branches, causing them to snap or bend. Properly supporting and protecting shrubs helps prevent this damage.
- Minimize water loss: Even in winter, evergreens continue to lose water through their leaves. Protection ensures that they don’t dry out, especially when the ground is frozen and roots cannot absorb water.
- Maintain plant health: Stress from cold, wind, and moisture loss can weaken shrubs, making them more susceptible to diseases and pests. Proper winter care strengthens their resistance and promotes healthier growth in spring.
Types of Evergreen Shrubs That Need Protection in December
Different evergreen shrubs have varying tolerance levels to cold, but many benefit from extra care during the winter months:
- Boxwood (Buxus)
- Description: Known for its dense, green foliage, boxwood is often used for hedges and topiaries. It is vulnerable to winter burn and requires careful protection during harsh winters.
- Best protection: Burlap wraps, anti-desiccant sprays.
- Holly (Ilex)
- Description: With its glossy leaves and bright red berries, holly is a classic winter shrub. Cold winds and heavy snow can damage its leaves and branches.
- Best protection: Windbreaks, burlap covers, and regular watering before the ground freezes.
- Rhododendron
- Description: Rhododendrons have large, leathery leaves that can suffer from desiccation during winter. They are prone to leaf curling as a sign of stress.
- Best protection: Mulching, windbreaks, and proper watering.
- Juniper
- Description: Junipers are hardy but can still suffer from winter burn, particularly in exposed areas. Heavy snow can also cause branch breakage.
- Best protection: Wrapping branches, mulching, and using anti-desiccants.
- Yew (Taxus)
- Description: Yews are versatile, shade-tolerant evergreens that can experience winter damage if exposed to extreme cold or drying winds.
- Best protection: Burlap screens, mulching, and adequate moisture.
How to Properly Protect Evergreen Shrubs in December
Taking the right steps to protect your evergreen shrubs can mean the difference between a thriving plant and one that struggles through winter. Here’s how to do it effectively:
1. Apply Mulch Around the Base
- Why mulching matters: Mulch insulates the roots and soil, keeping the ground warmer and helping retain moisture. It also prevents soil from freezing and thawing, which can damage roots.
- How to mulch: Spread a 2-4 inch layer of organic mulch, such as bark chips, straw, or compost, around the base of the shrub. Keep the mulch a few inches away from the trunk to prevent rot.
2. Water Thoroughly Before the Ground Freezes
- Why hydration is essential: Evergreens lose water through their leaves even in winter. Giving them a good drink before the ground freezes helps ensure they have enough moisture to last through dry spells.
- How to water: Deeply water the soil around the shrub, focusing on the root zone. Make sure the water penetrates at least 6-8 inches into the soil.
3. Use Burlap Screens or Wraps
- Why burlap works: Burlap provides a breathable shield that protects shrubs from harsh winds and sun exposure, reducing the risk of winter burn.
- How to use burlap: Create a windbreak by staking burlap a few inches away from the shrub, or loosely wrap the shrub in burlap, securing it with twine. Ensure there is enough space to allow air circulation.
4. Protect Branches from Snow and Ice
- Prevent damage from heavy snow: Snow and ice can weigh down branches, causing them to bend or break. Gently shake off heavy snow after storms to prevent damage.
- How to support branches: Use twine to loosely tie up branches, or place a wooden frame around the shrub to support the structure. Avoid tying branches too tightly, as this can cause damage.
5. Apply Anti-Desiccant Sprays
- Why use anti-desiccants: These sprays form a protective layer on the leaves, reducing moisture loss and preventing winter burn. They are especially useful for broadleaf evergreens like rhododendrons and holly.
- How to apply: Spray the foliage on a mild day when temperatures are above freezing. Reapply as needed throughout the winter, following the product instructions.
Common Mistakes to Avoid When Protecting Evergreen Shrubs in December
Winter care for evergreens is relatively straightforward, but there are some common mistakes to watch out for:
- Over-wrapping shrubs: Wrapping shrubs too tightly can restrict airflow and lead to mold growth. Always use breathable materials like burlap and leave space for air to circulate.
- Ignoring watering needs: Many gardeners assume that evergreens don’t need water in winter. However, dry conditions can lead to serious damage. Water deeply before the ground freezes and during winter thaws.
- Using plastic covers: Plastic can trap moisture, leading to condensation and fungal issues. Stick to breathable fabrics for winter protection.
Benefits of Protecting Evergreen Shrubs in December
- Prevents winter burn and browning: Proper protection reduces moisture loss from leaves, keeping shrubs green and healthy throughout winter.
- Avoids breakage and structural damage: Supporting branches and clearing heavy snow prevents breakage, ensuring your shrubs maintain their shape and integrity.
- Encourages strong spring growth: Healthy shrubs come out of winter strong and ready to grow, leading to more vigorous growth and lush foliage in spring.
Best Practices for Protecting Evergreen Shrubs in December
- Monitor weather forecasts: Pay attention to cold snaps, heavy snow, and windy conditions. Be prepared to take action when adverse weather is predicted.
- Check protection regularly: Inspect your shrubs throughout winter to ensure that the burlap, ties, or other protective measures are still in place and haven’t been disturbed by wind or animals.
- Choose location wisely: If planting new evergreens, consider placing them in sheltered locations that offer some natural protection from harsh winds.
