When to Plant

Planting time depends on your growing season:

• Best sown in early autumn to early winter
• Can also be planted in early spring if the weather is cool
• Avoid peak summer heat which causes bolting and bitterness

For a continual supply, sow seeds every 2 weeks in cooler months.

Where to Plant

Japanese Minowase Radish prefers:

• Full sun to partial shade (4–6 hours of direct light)
• Deep, loose, well-draining soil free of stones and clumps
• Soil pH between 5.8 and 6.8
• Raised beds or deep containers (at least 12–15 inches) for optimal root development

Properly prepared soil helps the roots grow long and straight.

How to Plant

1. Prepare the soil by digging deeply and mixing in compost
2. Sow seeds ½ inch deep and 2 inches apart, in rows 12 inches apart
3. Cover lightly with fine soil and water gently
4. Thin seedlings to 4–6 inches apart when 2–3 inches tall

Keep soil moist but not waterlogged. Seeds germinate within 5–7 days.

How to Care

Japanese Minowase Radish is low-maintenance with proper care:

• Watering: Keep soil evenly moist to prevent cracking
• Thinning: Essential for uniform, straight roots
• Feeding: Use a balanced organic fertilizer once during mid-growth
• Mulching: Retains moisture and reduces weeds

• Pest Control: Monitor for flea beetles, aphids, and root maggots—use neem spray or row covers

Do not delay harvesting, as older roots may turn woody or spongy.

Companion Plants

Companion planting improves growth and deters pests:

• Grow near lettuce, spinach, and carrots
• Beneficial with peas and beans which enrich the soil
• Marigold helps repel common radish pests
• Avoid planting next to potatoes or brassicas, which may compete or share pests

Interplanting radish also acts as a trap crop for aphids and beetles.

Harvesting

Japanese Minowase Radishes are usually ready in 50–70 days.

• Harvest when roots reach 12–18 inches in length
• Loosen soil around the root before pulling to avoid breakage
• Wash gently and store in cool, dark conditions

They can be refrigerated for up to 2 weeks or fermented for longer shelf life.

Uses

Minowase radish is highly versatile in the kitchen:

• Eaten raw in salads, wraps, or slaws
• Grated as a garnish or mild radish condiment
• Excellent for fermented pickles and kimchi-style preparations
• Used in soups, stir-fries, and stews
• Helps with digestion and detoxification

Both root and leaves are edible, making it a zero-waste vegetable.
