HOW TO GROW RADISH
Beginner Tip
- Best grown in cool weather.
- Direct sow only — radishes dislike transplanting.
- Harvest young for sweeter, crisp roots.
- Sow small batches every 2 weeks for continuous harvest.
1. Choose a Variety
Easy Bigginer Variety:
- Cherry Belle Radish
- French Breakfast Radish
- Daikon
2. Growing Timeline
| onth | Growth Stage | Tasks |
|---|---|---|
| July | Preparation & Sowing | Choose a sunny spot with loose soil. Add compost and remove stones. Direct sow seeds 1–2 cm deep and 3–5 cm apart. Keep soil moist. |
| August | Germination & Seedling Growth | Seeds sprout in 4–10 days. Thin crowded seedlings to prevent tiny roots. Water regularly for even growth. Protect from slugs/snails. |
| September | Root Development | Radishes begin swelling underground. Keep watering consistent to avoid splitting or woody roots. Harvest small radishes early for best flavor. |
| October | Harvesting | Most spring radishes are ready. Pull when roots reach golf-ball size or desired size. Replant every 2 weeks for continuous harvest. |
| November | Late Harvest / Bolting Risk | Warm weather may cause flowering (bolting). Harvest remaining radishes quickly. Use shade cloth in hotter areas. |
| December | Hot Weather Management | Spring radishes struggle in heat. Try heat-tolerant or Asian radishes if growing. Mulch heavily and water deeply. |
| January | Rest or Specialty Types | Difficult time for common radishes in Sydney heat. Grow only tropical/heat-tolerant varieties in partial shade. |
| February | Soil Recovery & Planning | Improve soil with compost and prepare for autumn sowing. |
| March | Autumn Sowing Begins | Excellent time to sow again. Cooler temperatures improve flavor and texture. |
| April | Fast Autumn Growth | Continue watering and thinning. Growth is quick in mild weather. |
| May | Harvesting | Harvest autumn crops. Daikon and winter radishes continue enlarging. |
| June | Winter Growth | Slow but steady growth. Protect from heavy rain and waterlogging. Prepare for another July sowing cycle. |
3. Growing Conditions
- Loose, well-draining soil (6.0-7.0ph)
- Full sun (6+ hours) or light partial shade
- Cool-season crop (10–24°C)
4. Planting
0. Prepare soil:
- Loosen soil deeply and remove rocks or hard clumps.
- Mix in compost before planting.
1. Planting Steps
From Seeds
- Direct sow seeds 1–2 cm deep.
- Space seeds:
- Small radishes: 3–5 cm apart
- Large/winter radishes: 10–15 cm apart
- Water gently after sowing.
- Thin seedlings once they sprout to avoid overcrowding.
From Seedlings: Radishes dislike transplanting, so always sow directly where they will grow.
2. POT Planting
- Radishes are shallow-rooted, so they grow well in containers. The key is depth + loose soil, not width.
- Avoid overcrowding (thin seedlings early).
- Choose wide pots or trays for multiple radishes.
Pot Size Guide
| Radish Type | Minimum Pot Depth | Recommended Pot Width | Notes |
|---|---|---|---|
| Small spring radishes (e.g. Cherry Belle Radish) | 15–20 cm | 20–30 cm | Fastest growing, ideal for pots |
| Medium varieties (e.g. French Breakfast Radish) | 20–25 cm | 25–35 cm | Slightly deeper roots, still easy |
| Large winter radishes (e.g. Daikon) | 30–45 cm+ | 30–50 cm+ | Needs deep soil to grow straight |
5. Watering
- Keep soil evenly moist but not soggy.
- Water deeply 2–4 times weekly depending on weather.
- Uneven watering can cause:
- Cracking
- Woody roots
- Strong spicy flavor
Mulching helps keep moisture stable.
6. Supporting & Pruning
Supporting: Most radishes do not need support. Large varieties like Daikon may benefit from loose, deep soil so roots grow straight.
Pruning: No pruning required.
You can:
- Remove damaged leaves
- Harvest a few young leaves for salads
Tips
- Avoid removing too many leaves because roots need them for growth.
7. Feeding
| Stage | Feeding |
|---|---|
| Before planting | Add compost or aged manure |
| Early growth | Balanced vegetable fertilizer lightly applied |
| Mid growth | Usually no extra feeding needed |
Avoid too much nitrogen because it causes:
- Large leaves
- Small roots
8. Pollination
Radishes grown for roots do not need pollination.
If left to flower:
- Bees pollinate the flowers
- Plants produce seed pods and seeds
9. Common Problems
| Problem | Cause | Solution |
|---|---|---|
| Tiny roots | Crowded seedlings | Thin plants properly |
| Cracked roots | Uneven watering | Water consistently |
| Woody or pithy roots | Left too long in soil | Harvest earlier |
| Very spicy flavor | Heat or drought stress | Grow in cool weather and water well |
| Long roots with little bulb | Too much shade or nitrogen | Increase sunlight and reduce nitrogen |
| Forked roots | Rocky or compact soil | Use loose stone-free soil |
| Bolting (flowering early) | Hot weather | Grow in cooler months |
| Holes in leaves | Flea beetles/slugs | Use netting or organic controls |
| Root rot | Poor drainage | Improve drainage and avoid overwatering |
10. Harvesting
Small Spring Radishes
- Harvest when roots reach golf-ball size, firm and crisp
- Usually ready in 4–6 weeks
Winter Radishes
- Like Daikon is ready in 6–10 weeks and can grow much larger.
- Pull gently from moist soil.
- Do not leave radishes too long or they become woody and hollow.
11. Storage
| Storage Method | Duration |
|---|---|
| Refrigerator | 1–3 weeks |
| Remove leaves first | Helps roots stay crisp |
| Wrapped in damp towel | Keeps moisture |
| Root cellar/cool area | Winter radishes last longer |
Radish greens can also be eaten fresh in salads, soups, or stir-fries.
In Asian countries, they dry radish for longer storage.
