These crops use winter to establish strong root systems.

🌬 How to Protect Winter Veg Outdoors
A few simple steps make winter growing far more successful.
❄️ Use Fleece on Frosty Nights
Covers:
- keep soil warmer
- stop frost scorching leaves
- reduce wind chill
🍃 Mulch Heavily
Mulching:
- insulates roots
- prevents soil freeze
- stops erosion
Use compost, leaves or straw.
⛺ Add Tunnels or Cloches
Especially useful for:
- salad leaves
- carrots
- young brassicas
🌧 Avoid Waterlogging
Winter wet kills more plants than frost.
Improve drainage by:
- adding grit
- raising beds
- avoiding compacting soil
💡 Common Winter Growing Problems
❌ Leaves turning yellow
Usually winter wet — improve airflow and mulch.
❌ Slug damage
Use traps, pellets (wildlife-friendly), or barriers.
❌ Crops not growing
Normal — light levels are low.
❌ Carrots splitting
Too much winter rain — grow under cover next time.
❌ Fleece blowing away
Secure with pegs or boards.
🌱 What to Expect in Spring
By March–April:
- overwintered crops will burst into growth
- early harvests will begin
- beds will already be productive
- you’ll be ahead of the gardening season
Winter-growing = earlier, healthier crops.
