Watermelon Radish

100 Seeds

Watermelon Radish is a cool-season radish variety with a pale green-white exterior and a beautiful pink-to-red center. It develops the best color, flavor, and crisp texture in cool weather. In the Gulf, especially Kuwait, timing is very important—avoid the extreme summer heat.

🌱 Best Sowing Time

• Best sowing period: October–February.
• Best months in Kuwait: November–January.
• A second sowing can be made in February if temperatures remain cool.
• Avoid sowing during May–September, when Gulf temperatures are generally too high for quality root development.
• Ideal soil temperature for germination: approximately 10–24°C.

🌿 How to Sow the Seeds

1. Choose a location with full sun during the cooler season.
2. Prepare loose, deep, sandy-loam or fertile soil that drains well.
3. Remove stones and hard clumps because they can cause misshapen roots.
4. Sow seeds approximately 1–1.5 cm deep.
5. Space seeds about 3–5 cm apart.
6. Keep rows approximately 15–20 cm apart.
7. Water gently immediately after sowing.
8. Keep the soil consistently moist, especially during germination and root formation.

⏱ Germination

• Seeds generally germinate within 4–10 days under suitable conditions.
• Thin seedlings when they become crowded, leaving approximately 8–10 cm between plants for larger roots.
• Avoid disturbing the roots after thinning.

🌱 Growing & Care

• Sunlight: Full sun is best during the cooler Gulf season.
• Soil: Loose, fertile, deep, and well drained.
• Watering: Water regularly and evenly. Inconsistent watering can produce small, tough, or split roots.
• Avoid both drought stress and waterlogging.
• Fertilizing: Mix compost into the soil before sowing. Avoid excessive nitrogen because it encourages leafy growth instead of good root development.
• Keep weeds under control because radishes have relatively shallow roots.
• A thin layer of mulch can help maintain soil moisture and temperature.

🥕 Harvest

• Watermelon radishes are generally ready to harvest in approximately 50–70 days, depending on variety and growing conditions.
• Harvest when the roots reach a useful size and before they become overly mature.
• In the Gulf, harvesting during the cooler part of the season helps maintain better texture and flavor.
• Pull roots carefully from moist soil.
• Remove the leaves after harvest and store the roots in a cool place.

🌡 Gulf Climate Tips

• Cool-season cultivation is essential for good-quality Watermelon Radish.
• In Kuwait, November and December are particularly favorable for sowing.
• If temperatures suddenly rise, provide light afternoon shade to help keep the soil cooler.
• Use mulch to reduce soil temperature and moisture loss.
• Water in the early morning during warm weather.
• Avoid allowing the soil to dry out completely.
• High temperatures can cause radishes to become pithy, spicy, or develop poor roots.
• For continuous harvests, sow a small batch every 2–3 weeks during the suitable cool season.
