🧄❄️ Planting Garlic in December: Essential Tips for a Successful Harvest
🧄 Introduction: Can You Plant Garlic in December?
Yes — garlic can be planted in December, and in many parts of the UK it can still produce an excellent crop. While autumn planting is ideal, December planting is perfectly acceptable if the soil is workable and not frozen or waterlogged. Garlic actually benefits from a period of cold, which helps bulbs split into cloves properly and form strong, well-sized heads.

🌱 Is December a Good Time to Plant Garlic?
✅ December Planting Works Well If:
- Soil is not frozen or waterlogged
- You plant hardneck or hardy softneck varieties
- Garlic is planted as soon as possible
⚠️ December Is Less Ideal If:
- Soil is heavy clay and saturated
- You experience prolonged hard frost
- Cloves are planted too shallow
Garlic is very resilient — the biggest enemy is wet soil, not cold.
🧄 Best Garlic Varieties for December Planting (UK)
🟣 Hardneck Garlic
- Very cold-hardy
- Produces larger cloves
- Often stronger flavour
⚪ Softneck Garlic
- Stores longer
- Slightly less cold-tolerant
- Still suitable for December in mild areas
Avoid supermarket garlic, which may be treated to prevent sprouting.
🌍 Choosing the Right Site
Garlic prefers:
- Full sun
- Free-draining soil
- An open position with good airflow
Raised beds or containers are ideal for winter planting, especially on heavy soils.
🌱 How to Plant Garlic in December (Step-by-Step)
1️⃣ Prepare the Soil
- Remove weeds
- Improve drainage with grit or compost
- Rake to a fine tilth
2️⃣ Split the Bulb
- Separate into individual cloves
- Keep the papery skin intact
- Use the largest cloves for planting
3️⃣ Plant the Cloves
- Plant pointed end up
- Depth: 5–7 cm
- Spacing: 10–15 cm apart
- Rows: 25–30 cm apart
Firm soil gently around each clove.
❄️ Winter Care After Planting
- Shoots may appear before winter — this is normal
- Garlic tolerates frost well
- Avoid watering unless conditions are very dry
- Mulch lightly if soil is exposed
Do not worry if growth pauses during cold spells.
🌱 Spring Growth & Feeding
From February onwards:
- Growth accelerates
- Keep beds weed-free
- Apply a light nitrogen feed if soil is poor
Stop feeding once bulbs begin to swell in late spring.
🧄 When to Harvest Garlic Planted in December
- Ready June to July
- Harvest when lower leaves turn yellow
- Lift carefully and dry (cure) in a warm, airy place
December-planted garlic may be slightly smaller than October-planted, but still very good quality.
⚠️ Common Problems & How to Avoid Them
Cloves rotting in soil
- Improve drainage
- Avoid planting too deep
Small bulbs
- Poor soil fertility
- Small cloves planted
Lots of leaves, small bulbs
- Too much nitrogen late in season

Can I plant garlic in pots in December?
Yes — containers are excellent for winter drainage.
Should I cover garlic with fleece?

🧠 Key Takeaway
Planting garlic in December is a reliable and worthwhile option for UK gardeners. As long as soil drains well and cloves are planted correctly, garlic will overwinter happily and reward you with a flavourful summer harvest. Cold weather helps, wet soil harms — focus on drainage and you’ll succeed.
