Raphanus sativus
A fast, hardy root crop for UK gardens, best grown in cool weather for crisp roots with a clean peppery bite. Sow little and often in open ground or a deep container, keep the soil evenly moist, and pull roots promptly before they get woody.
Step-by-step instructions for growing Radish
Sow seeds thinly in shallow drills around 12th March - 17th August and cover with a light layer of fine soil. Sow a fresh batch every 14 days for a steady supply, and keep the drills evenly watered after sowing.
When the seedlings are large enough to handle, from 9th June, thin them to leave the strongest plants apart. Snip surplus seedlings at soil level so you don't disturb the roots you want to keep.
From 9th June until 22nd October, water little and often so the soil stays evenly moist. Dry soil makes roots hot, woody and quick to bolt, especially in warm spells.
Lift roots as soon as they reach a usable size, from 24th June through 24th June - 22nd October. Don't leave them in the ground too long, or they'll become pithy and tough. Pick them promptly and re-sow a fresh row to keep the crop coming.

Companion planting can deter pests, improve pollination, and make better use of space. Some plants confuse pests or attract beneficial insects; others improve soil or offer shade to neighbours that need it.
