Health Benefits

Radishes are a cole crop with edible roots.  Radishes can be used as a pest repellent for squash crops.

Soil should be well-drained and friable.  Radishes will tolerate clay.  High organic soils have a better texture; they tend not to be hard and crusty.

In the absence of a soil test, broadcast one cup of 10-10-10 per 10-foot row and mix into the top 4 inches of soil. Use a composted manure or green manure to add nutrients and texture to the soil.

Plant seed 1/2 inch deep into moist soil.  Plant in rows about 2 to 2 1/2 feet apart. Spring sow in March, Fall sow in August or later.  Thin spring radishes to 1 inch, and thin winter radishes to 3 inches.  Plant radishes in 3 foot blocks

Place 1 to 2 inches of mulch into the planting bed after true leaves appear. This will keep the soil from crusting.  Gently hoe weeks, or hand pull them to protect the roots. Plants that lack water will grow slowly and taste hot and mealy.

Cucumbers, squash and nasturtiums

Spring: Champion, Cherry Belle, Easter Egg and Icicle
Fall: Black Spanish and Tama

Water prior to harvest to make pulling easier.

Radishes provide protein, calcium and vitamin C
