- Sow direct from February to September in short repeat batches.
- Harvest window
- Harvest Cherry Belle, Hailstone and Sparkler roots young, usually within three to six weeks.
- Difficulty
- Easy
- Container suitability
- Use a trough or pot at least 15cm deep with drainage holes. Space plants 3–5cm apart; a wide container is more useful than an especially deep one. Sow a short row every 2–3 weeks rather than the whole packet at once.
- Frost sensitivity
- Hardy in cool weather
- Typical time to harvest
- Most radishes are ready 4–6 weeks after sowing. Check roots early and lift promptly for the crispest texture.
SOW
When to Sow Radish Mix (Cherry Belle, Hailstone & Sparkler) in the UK
Sow direct from February to September in short repeat batches.
Use that window as a practical starting point rather than a fixed deadline. In colder or exposed areas, delay outdoor sowing and planting; in mild sheltered areas, the earlier end of the range may work. Tender crops should remain protected until frost risk has passed.
Sowing Indoors
Indoor sowing is rarely useful. If the ground is very cold, sow in an unheated greenhouse trough or under a cloche rather than raising transplants.
Sowing Outdoors
Sow Radish Mix (Cherry Belle, Hailstone & Sparkler) directly where it will grow, about 1cm deep. Thin promptly, keep the row moist and repeat little and often through the season.
PLANT
Spacing and Planting Out
Thin seedlings to 3–5cm apart, with 15cm between short rows. Crowded plants make leaves rather than round roots.
Before planting outside, harden off indoor-raised plants over 7–10 days unless the crop is fully hardy and already accustomed to outdoor conditions. Water the planting hole or container first and avoid leaving young roots exposed to sun or wind.
SMALL SPACES
Growing Radish Mix (Cherry Belle, Hailstone & Sparkler) in Pots and Containers
Use a trough or pot at least 15cm deep with drainage holes. Space plants 3–5cm apart; a wide container is more useful than an especially deep one. Sow a short row every 2–3 weeks rather than the whole packet at once.
Container checklist
- Use drainage holes and raise pots slightly so surplus water can escape.
- Fill with fresh peat-free compost suited to edible crops.
- Leave a watering lip below the rim and check pots more often in sun or wind.
- Use a strong support at planting time if the mature crop will climb or become top-heavy.
CARE
Watering and Feeding
Keep the compost evenly moist. A sudden dry spell followed by heavy watering can split roots, while prolonged dryness makes them hot, pithy or woody. No extra feed is normally needed in fresh compost.
Variety note: The three colours mature at slightly different rates, so check roots individually rather than lifting the row at once.
WATCH FOR
Common Problems
Leaves but no round roots
Crowding, shade, rich nitrogen feed or hot weather can all delay root formation. Thin early and use a bright, cool position.
Flea beetle holes
Tiny holes in young leaves are common. Keep plants growing steadily and use fine insect mesh if damage is severe.
Pithy or split roots
The crop was left too long or watered unevenly. Harvest small and make repeat sowings.
PICK
Harvesting Radish Mix (Cherry Belle, Hailstone & Sparkler)
Harvest Cherry Belle, Hailstone and Sparkler roots young, usually within three to six weeks.
Most radishes are ready 4–6 weeks after sowing. Check roots early and lift promptly for the crispest texture. Harvest in the coolest part of the day where practical and handle produce gently. Regular picking encourages continued cropping in fruiting and cut-and-come-again plants.
GROW TOGETHER
Companion Plants
Radishes fit between slower lettuces, peas or carrots because they are harvested quickly. Use the arrangement to share space, not as a promise of pest prevention.
QUESTIONS
Frequently Asked Questions
Can I grow Radish Mix (Cherry Belle, Hailstone & Sparkler) in pots?
Use a trough or pot at least 15cm deep with drainage holes. Space plants 3–5cm apart; a wide container is more useful than an especially deep one. Sow a short row every 2–3 weeks rather than the whole packet at once.
How long does Radish Mix (Cherry Belle, Hailstone & Sparkler) take to harvest?
Most radishes are ready 4–6 weeks after sowing. Check roots early and lift promptly for the crispest texture.
Why is my Radish Mix (Cherry Belle, Hailstone & Sparkler) not making roots?
Thin the seedlings, avoid high-nitrogen feed and check they receive enough light. Very hot weather can also push radishes into flower before roots swell.
