Rainbow Mixed Radish is a colorful blend of radish varieties producing red, pink, purple, white, and bi-colored roots with crisp texture and flavors ranging from mild to slightly spicy. It is ideal for fresh salads, garnishes, pickling, and vegetable platters. In the Gulf region, it performs best during the cool season.

Best Planting Time

• October to February (recommended)
• Sow during the cool season for the best root development.
• Avoid planting during the hottest summer months.

Seed Preparation

• No soaking is required.
• Use fresh, high-quality seeds.
• No cold stratification is needed.

Soil Preparation

Rainbow Radishes grow best in loose, fertile, stone-free, well-drained soil.

Recommended mix:

• 40% Sandy garden soil
• 30% Well-rotted compost
• 20% Coco peat
• 10% Perlite or coarse sand

Ideal soil pH:

• 6.0–7.0

Sowing Method

• Direct sowing is recommended.
• Sow seeds 1–1.5 cm deep.
• Place 1 seed per hole.
• Thin seedlings after germination if necessary.

Temperature & Light

• Ideal germination temperature: 12–22°C
• Ideal growing temperature: 15–25°C
• Requires 6–8 hours of direct sunlight daily.
• In warmer Gulf regions, light afternoon shade helps produce sweeter, smoother roots.

Watering

• Keep the soil evenly moist throughout growth.
• Water whenever the top 2–3 cm of soil begins to dry.
• Consistent watering prevents cracking and excessive pungency.
• Avoid waterlogging.

Germination Time

• 4–8 days

Plant Spacing

• 8–10 cm between plants.
• 25–30 cm between rows.

Harvest

• Harvest 25–40 days after sowing, depending on the variety in the mix.
• Pick roots when they reach 3–5 cm in diameter for the best flavor and crisp texture.
• Harvest regularly to prevent woody or overly spicy roots.

Fertilization

• Mix compost into the soil before planting.
• Apply a light balanced fertilizer once after seedlings are established.
• Avoid excessive nitrogen, as it promotes leaves instead of root growth.

Gulf Climate Tips

• Grow only during the cool season.
• Water early in the morning.
• Apply a thin layer of mulch to reduce soil temperature and conserve moisture.
• Succession sow every 2–3 weeks for continuous harvests.
• Monitor for aphids, flea beetles, cabbage worms, root maggots, and downy mildew.
• Rainbow Mixed Radish is excellent for home gardens, raised beds, containers, school gardens, and vegetable gardens throughout the Gulf.
