What Flowers to Cover in a Freeze Warning

When winter arrives and temperatures plummet, many plants struggle to survive the harsh conditions of a freeze warning. It’s crucial to understand which flowers can withstand cold temperatures and which ones require extra protection. Here’s a comprehensive guide on what flowers should be covered during a freeze warning:

1. Hardy Perennials

• Geraniums: These vibrant annuals thrive in cool weather and are well-suited for frost protection.
• Aster: Known for their daisy-like blooms, asters provide excellent coverage against freezing temperatures.
• Petunias: These colorful annuals add a burst of color even when temperatures drop.

2. Tender Annuals

• Marigolds: With their bright yellow petals, marigolds are ideal for covering delicate plants like tomatoes or peppers.
• Zinnias: These sun-loving flowers come in various colors and are perfect for adding warmth and color to your garden.

3. Evergreen Shrubs

• Boxwood: Evergreen boxwoods retain their leaves through cold spells, providing a protective barrier for surrounding plants.
• Yew: Yews offer a dense shade that helps keep other plants warm and protected from the bitter cold.

4. Vegetable Plants

• Tomatoes: If you have tomato plants in your garden, they need special care as they may not tolerate extreme cold. Covering them with frost cloth or blankets is essential.
• Peppers: Similar to tomatoes, peppers also benefit from frost protection. Use lightweight covers made of breathable materials to avoid suffocating the plants.

5. Herbs

• Basil: This fragrant herb loves heat but can handle light frosts. Protect it with a layer of mulch around its base.
• Chives: Chives are another hardy herb that can withstand brief freezes without damage.

6. Flowers That Require Protection

• Lilies: Lilies are sensitive to cold and should be covered with a thick layer of mulch or straw to protect their foliage.
• Hydrangeas: These large flowering shrubs often lose their leaves when exposed to severe cold, so careful attention is needed.

7. Tips for Winter Care

• Mulching: Apply a thick layer of organic mulch around your plants to help insulate them from the cold ground.
• Water Management: Ensure proper watering before the first freeze to prevent water loss due to evaporation.
• Avoid Wind Exposure: Keep your plants away from strong winds, as they can exacerbate temperature drops.

By following these guidelines, you can ensure that your flowers remain beautiful and healthy throughout the winter months. Remember, every plant has different needs, so always check local gardening advice specific to your area. Happy planting!
