Onion Sets for English Gardens – Spring & Overwintering Varieties

In England, spring-planted onion sets like Sturon and Red Karmen are best sown from early March through April. For overwintering types like Troy F1 and Senshyu Yellow, sow from mid-September to early November.

The relatively mild English climate offers excellent conditions for both spring and autumn sowings—just ensure well-draining soil to avoid rot during wet periods.

Best Time to Plant Onion Sets in England

• Spring sets: Plant from early March once the soil is workable
• Overwintering sets: Plant mid-September to early November

In most of England, onions do well in open, sunny plots. Use mulch or fleece if planting late in the season or in exposed areas.

How to Grow Onion Sets in England

• Pick a sunny location with well-drained soil
• Push sets into the soil so only the tip is visible
• Space 10cm apart with 25cm between rows
• Use netting to protect from birds dislodging young sets
• Water occasionally—overwatering can lead to rot
