Seed Depth: 1/4–1/2 inch

Seed Spacing: 1–2 inches

Row Spacing: 8–12 inches

Sunlight: Full sun to partial shade

Days to Sprout: 3–7 days

Days to Maturity: 25–30 days

Growth Habit: Upright, root vegetable

Sunlight: Thrives in full sun but tolerates partial shade, especially in warmer climates.

Soil Type: Prefers loose, well-drained soil with a pH of 6.0–7.0. Adding compost improves growth.

When to Plant: Sow seeds directly outdoors in early spring or late summer for a fall crop. Radishes grow best in cool weather.

Direct Sowing: Plant seeds 1/4–1/2 inch deep, spacing them 1–2 inches apart in rows 8–12 inches apart. Thin seedlings to the desired spacing once they germinate.

Indoor Sowing: Not recommended; radishes grow best when directly sown outdoors.

Succession Planting: Sow every 2–3 weeks for a continuous harvest during cool seasons.

Watering: Water consistently to keep the soil evenly moist but not waterlogged. Avoid letting the soil dry out completely.

Fertilizing: Use a low-nitrogen fertilizer or compost at planting to encourage strong root development. Avoid excessive nitrogen, which promotes leafy growth over root formation.

Pruning: No pruning needed, but remove weeds to reduce competition.

Pest and Disease Control: Monitor for flea beetles and root maggots. Use row covers and crop rotation to minimize risks.

When to Harvest: Harvest roots when they are 4–6 inches long, typically 25–30 days after planting. Harvest promptly to prevent radishes from becoming woody.

How to Harvest: Gently pull roots from the soil by their tops. Loosen soil around larger roots if needed.

Seed Collection: Allow some plants to bolt and form seed pods. Collect seeds once pods are dry and brittle.

Storing Seeds: Store seeds in an airtight container in a cool, dry place.
