🌱 What to Cover in the Garden During February Frosts

February frosts can arrive suddenly and cause damage just as plants begin to wake up. Knowing what actually needs covering — and what doesn’t — helps you protect vulnerable plants without creating damp or disease problems.

❄️ Why February Frosts Are So Damaging

February is risky because:

• Temperatures still fall below freezing
• Daytime warmth encourages new growth
• Buds and young shoots are frost-sensitive

Plants are often more vulnerable now than earlier in winter.

🌸 Early-Flowering and Budding Plants

These should be top priority during frosty nights.

Cover:

• Plants already in bud
• Early spring-flowering plants
• Soft new growth on perennials

Why: Buds and flowers are easily killed by frost, reducing flowering and fruiting later.

🌿 Tender and Borderline-Hardy Plants

Some plants survive winter but suffer in late frosts.

Cover:

• Tender perennials
• Half-hardy shrubs
• Plants grown in exposed or windy spots

A light fleece layer overnight is usually enough.

🪴 Container and Potted Plants

Pots are far more vulnerable than plants in the ground.

Always cover or move:

• Containers with tender plants
• Newly planted pots
• Pots showing new growth

Roots freeze much faster in containers, even if foliage looks fine.

🌱 Young and Newly Planted Plants

Recently planted plants haven’t established strong roots yet.

Cover:

• Newly planted trees and shrubs
• Young perennials
• Fresh transplants

Fleece or cloches help protect roots and reduce frost shock.

🍓 Fruit Plants with Swelling Buds

Fruit plants may be hardy, but buds are not.

Cover when frost is forecast:

• Early-flowering fruit trees
• Soft fruit bushes showing bud swell

Frost-damaged buds can mean reduced harvests later.

🌾 Overwintered Vegetables and Seedlings

Some winter crops benefit from extra protection.

Cover:

• Young leafy greens
• Overwintered seedlings
• Early crops growing under cover

This prevents frost scorch and growth checks.

🌬️ Plants in Exposed or Frost-Pocket Areas

Even hardy plants can suffer in the wrong location.

Cover plants that are:

• In open or windy gardens
• In low-lying frost pockets
• Near walls where cold air settles

Wind chill increases frost damage significantly.

🛡️ What to Use for Covering

Best options include:

• Horticultural fleece
• Cloches
• Old sheets or blankets (temporary)
• Straw or mulch around roots

Always secure covers so they don’t blow away.

❌ What Does NOT Need Covering

These usually cope fine:

• Fully dormant hardy trees
• Established shrubs
• Bare soil and empty beds

Over-covering hardy plants can cause damp and disease.

⚠️ Common Covering Mistakes to Avoid

Avoid:

• Leaving covers on during the day
• Using plastic directly on plants
• Trapping moisture around stems
• Forgetting to remove covers when frost passes

Covers should protect from cold, not smother plants.

🌼 Simple February Frost Rule

If a plant is:

• Tender
• In a pot
• Newly planted
• Actively growing

…it should be covered during February frosts.

Targeted protection on cold nights makes all the difference — and prevents unnecessary damage before spring truly arrives.
