🥔🌱 When to Plant Potatoes in the UK
🥕 Introduction: Why Timing Matters for Growing Potatoes
Knowing when to plant potatoes in the UK is one of the most important factors for a successful harvest. Plant too early and frost can damage young shoots; plant too late and yields may be reduced. Because the UK climate varies by region and season, potato planting is guided by variety type, soil temperature, and frost risk rather than fixed dates.

🥔 Understanding Potato Types and Planting Times
Potatoes are grouped by how long they take to grow.
✔ first early
✔ second early
✔ maincrop
Each group is planted at a different time.
🌱 When to Plant First Early Potatoes (UK)
Planting time:
✔ late March to early April
First early potatoes are the earliest to go into the ground.
✔ soil should be workable
✔ frost protection may be needed
✔ often planted after chitting
They are ready to harvest around June.
🌱 When to Plant Second Early Potatoes (UK)
Planting time:
✔ early to mid-April
Second earlies follow shortly after first earlies.
✔ slightly longer growing period
✔ less frost risk than earlier plantings
✔ good balance of yield and speed
Harvest usually begins in July.
🌱 When to Plant Maincrop Potatoes (UK)
Planting time:
✔ mid to late April
Maincrop potatoes need the longest growing season.
✔ less risk from frost
✔ produce larger yields
✔ suitable for storage
Harvest typically takes place from late summer to early autumn.
🌡️ Soil Temperature and Frost Risk
Potatoes grow best when conditions are right.
✔ soil temperature above 7°C
✔ no waterlogged ground
✔ frost protection ready for early shoots
Cold, wet soil can rot seed potatoes before growth begins.
🌍 Regional Differences in the UK
Planting times vary by location.
Cold Areas (Scotland, northern England, high ground)
✔ plant 1–2 weeks later
✔ use fleece for protection
Mild Areas (southern England, coastal regions)
✔ plant slightly earlier
✔ soil warms sooner
Always adjust to local conditions.
🌱 Can You Plant Potatoes Earlier Under Cover?
Yes, with protection.
✔ plant in pots or grow bags
✔ place in greenhouses or polytunnels
✔ protect from frost
This can produce very early crops, but requires careful management.
❄️ What Happens If Potatoes Are Hit by Frost?
Frost can damage foliage but not always kill plants.
✔ blackened shoots may regrow
✔ cover plants immediately
✔ earth up soil for protection
Severe frost can delay growth but usually doesn’t ruin the crop.

❌ planting into cold, wet soil
❌ ignoring frost forecasts
❌ not earthing up shoots
