🌿 How to Plant Radish Seeds (Correctly)

Radishes are direct-sow seeds — do not start indoors.

✔ When to Plant

• Early spring

• Late summer

• Fall

They prefer cool weather and often bolt in hot summer.

✔ Soil Conditions

• Loose, well-drained

• Not too high in nitrogen

• pH 6.0–7.0

• Avoid compacted clay soil

✔ Planting Depth & Spacing

• Plant seeds ½ inch deep

• Space 1–2 inches apart

• Rows 8–10 inches apart

Do not overcrowd — this causes root distortion.

💧 Watering & Care

Radishes need:

• consistent moisture

• never water-logged soil

• shallow frequent watering

If radishes experience drought → they become hot & spicy.

🥕 Harvesting Radishes

Do NOT wait too long.

• Harvest 20–30 days after sowing

• Pull when radishes are golf-ball sized or smaller

• Remove immediately after reaching size

If they sit in the ground too long:

• roots become pithy

• flesh grows woody

• flavor becomes harsh

So plant a new row every 7–10 days to keep fresh radishes coming.
