🥕🌱 When to Plant Turnips in the UK
🥕 Introduction: Turnips Are Fast—But Timing Makes the Difference
Turnips are a quick-growing, cool-season root crop that can be grown across much of the year in the UK if timed correctly. Plant too early into cold soil and germination is slow; plant during hot weather and roots can be woody or bolt. Knowing when to plant turnips in the UK helps you grow tender roots for summer eating and reliable crops for autumn and winter use.

📅 Best Time to Plant Turnips in the UK
Main sowing windows:
✔ March to June
✔ July to August
Turnips grow quickly, so they’re ideal for succession sowing every few weeks.
🌱 Early Turnip Sowing (March–April)
✔ sow from March once soil is workable
✔ use fleece or cloches in colder areas
✔ cool conditions encourage tender roots
Early sowings give harvests from May onwards.
🌱 Spring and Early Summer Sowing (April–June)
✔ most reliable period for sowing
✔ steady growth in mild temperatures
✔ roots develop quickly and evenly
These sowings provide turnips from June to August.
🌱 Late Summer Sowing (July–August)
✔ ideal for autumn and early winter harvests
✔ choose maincrop or storage varieties
✔ keep soil consistently moist
Late sowings avoid summer heat and produce better-quality roots.
🌡️ Soil Temperature and Growing Conditions
Turnips grow best when:
✔ soil temperature is 7–18°C
✔ soil is light, loose, and free-draining
✔ moisture is consistent during growth
Hot, dry soil leads to woody or bitter roots.
🌍 Regional Differences Across the UK
Cold Areas (Scotland, northern England, higher ground)
✔ start sowing outdoors in April
✔ rely more on late summer sowings
Mild Areas (southern England, coastal regions)
✔ sow from March
✔ longer sowing season overall
Always adapt to local soil warmth rather than fixed dates.
🪴 Growing Turnips in Containers
Turnips grow well in pots.
✔ use containers at least 20–25 cm deep
✔ space plants evenly
✔ keep compost consistently moist
Containers help control soil quality and moisture.
❄️ How Turnips Handle Cold and Heat
✔ seedlings tolerate light frost
✔ cool weather improves flavour
✔ heat increases bolting risk
Spring and late summer sowings usually give the best results.
🚫 Common Turnip Growing Mistakes
❌ sowing into hot, dry soil
❌ overcrowding seedlings
❌ letting soil dry out
❌ leaving roots in the ground too long
Thin early and harvest promptly for best texture.
