Radish

---

• Radishes mature quickly, often in less than a month, making them one of the easiest crops to grow. They're also perfect for filling gaps between slower crops due to their small size.

• Type: Cool-season annual root vegetable
• Height: 6-8 inches tall (foliage)
• Harvest Season: Fall, winter, early spring
• Sun Requirements: Full sun
• Soil Type: Loose, well-draining soil with moderate fertility
• Water Needs: Consistent moisture, dry spells cause radishes to become woody or split

• Direct seed in September–November for a fall crop, and in February - March for a spring crop.
• Avoid summer planting. Heat causes bolting and poor root formation.

• Choose a location with at least 6 hours of sun.
• Works well in raised beds and containers at least 6″ deep.
• Avoid recently fertilized soil as too much nitrogen promotes leafy tops instead of roots.

• Sow seeds ½ inch deep and 1 inch apart in rows 6–12 inches apart.
• For continuous harvest, plant small batches every 1–2 weeks within the planting window.
• Keep soil evenly moist during germination (3–7 days).

• Regular, shallow watering encourages even growth; inconsistent watering can cause cracking.

• Generally unnecessary in rich garden soil; if needed, use a low-nitrogen fertilizer.

• High temperatures or overcrowding cause radishes to bolt; harvest promptly.

• Generally not too many pests. 

Harvesting

• Most radishes mature in 25–30 days.
• Check often as radishes become woody and overly spicy if kept in the ground too long.
• Gently pull from the soil when roots are 1–1.5 inches in diameter.
• Remove greens immediately to prevent moisture loss! Store in the refrigerator for up to 2 weeks.

• Radishes are annuals and will not regrow once harvested.
• If allowed to flower and set seed, they can reseed themselves. The flowers are edible and attractive to pollinators.

• Radish flowers provide nectar for bees and beneficial insects.
• Excellent companion for lettuce, spinach, carrots, and cucumbers. Avoid planting near potatoes.

• For smoother roots, loosen soil to at least 6 inches deep before planting.
• Plant radishes between slower-growing crops to maximize space.
• Try roasting mature radishes for a milder, sweeter flavor—a great use for any that grow oversized.
