Protecting Your Plants in the Garden and Greenhouse Against Winter Weather: A Guide for New Beginnings

Winter in the UK and Ireland brings a quiet beauty to gardens, where frost-kissed landscapes promise new beginnings as the cold season gives way to spring's warmth. While the winter months can seem harsh on your garden, with its chilling winds, frosts, and shorter daylight hours, it's also a time of renewal. With a little preparation and the right care, your garden can survive the winter and thrive when spring arrives. Whether it's for your open garden, greenhouse, or polytunnel, protecting your plants during these colder months will ensure they come back stronger and more vibrant in the spring.

From hardy ground covers like Irish Moss (Sagina) to the resilient and low-maintenance Soleirola (Mind Your Own Business) and Catmint, to fragrant Lawn Chamomile, many plants can handle the cold with proper care. Here’s a full guide on how to protect them and others in your UK or Irish garden:

Key Winter Protection Tips for Your Plants

1. Use Ground Covers and Hardy Plants:

• Irish Moss (Sagina subulata): This low-growing, evergreen ground cover is perfect for creating a soft carpet. It is frost-tolerant and thrives in winter conditions, making it an excellent choice to protect soil and prevent erosion.
• Mind Your Own Business (Soleirola): Known for its dense, creeping foliage, this plant is also hardy enough to survive in colder climates and can help insulate soil while providing a soft green texture through the winter months.
• Catmint (Nepeta spp.): Catmint is a tough perennial that can withstand frost, blooming early in the spring. Its aromatic foliage and soft blue flowers make it both an attractive and practical addition to any garden, offering winter interest and spring growth.
• Lawn Chamomile (Chamaemelum nobile ‘Treneague’): A low-growing, aromatic herb that tolerates colder weather, this chamomile variety can create a beautiful, fragrant ground cover that remains green through winter.

2. Mulch for Insulation:

• Spread a thick layer of organic mulch (such as bark, compost, or straw) around your plants. This will help insulate the roots and regulate soil temperature. It also helps retain moisture during dry spells and keeps the soil from freezing.

3. Protect with Covers and Cloches:

• Use fleece or fabric covers to protect tender plants from frost. For individual plants, cloches, plastic tunnels, or cold frames can help shield them from the worst of the weather, especially when temperatures drop.

4. Create Windbreaks:

• Wind can be one of the harshest elements of winter, particularly for delicate plants. Use screens, hedging, or netting to reduce the impact of harsh winds, particularly for plants in exposed areas or in greenhouses and polytunnels.

5. Keep Greenhouses and Polytunnels Warm:

• Ensure that your greenhouse or polytunnel is properly sealed to prevent drafts and conserve heat. You can use thermal blankets or bubble wrap on the inside walls to help keep temperatures regulated. Avoid placing plants too close to the walls where they may get chilled.

6. Move Potted Plants Indoors or to Sheltered Areas:

• Any pots or containers should be moved to more sheltered spots, such as a greenhouse, shed, or against a south-facing wall to take advantage of the warmth of the sun. Alternatively, bring delicate plants indoors if possible.

7. Avoid Over-Watering:

• Plants in winter are dormant or semi-dormant and require far less water. Over-watering can lead to root rot, especially in cold, wet soil. Ensure that plants are only watered when the soil is dry to the touch.

8. Cut Back Dead Growth:

• Before the frost sets in, prune back any dead or damaged growth on plants to prevent diseases and ensure that the plant’s energy goes into maintaining healthy stems and roots.

9. Enhance Plant Health with Fertilizers:

• Before the cold weather hits, apply a balanced, slow-release fertilizer to strengthen plants, particularly those you wish to encourage growth in spring.

10. Keep Snow and Ice Away:

• If heavy snow falls, gently brush it off your plants with a broom to avoid breaking branches or stems. Try to prevent snow from accumulating on plants by adding covers where necessary.

11. Ensure Proper Drainage:

• Ensure that your garden, greenhouse, or polytunnel has proper drainage to prevent waterlogging. Cold, saturated soil can cause root damage and freeze plants.

12. Check for Pests and Diseases:

• Even in winter, check for signs of pests or disease. Mice, slugs, and aphids can still be active in sheltered spaces. Regularly inspect your plants and take action if necessary.

In Conclusion:

Winter might seem like a time of dormancy in your garden, but with careful planning and protection, your plants will emerge from the cold season ready to bloom again. Embrace the quiet beauty of the winter landscape while ensuring your plants are well-prepared to greet the warmth and promise of spring. By giving your garden the care it needs through the colder months, you can look forward to the new growth and vibrant colors of spring, knowing your plants are strong and protected.
