SUCCESSFUL RADISH FARMING

December 18, 2020 Hansie Britz

      

Radishes are a hardy, very easy-to-grow root vegetable that can be planted multiply times in a growing season. Plus, radishes can be harvested as soon as three weeks after planting.

Planting

Grow radishes in full sun or partial shade. Plant radishes in loose, well-drained soil. Remove soil lumps, rocks, and roots from radish planting beds. Obstructions can cause roots to grow malformed. Add organic matter to planting beds before sowing radishes. Radishes prefer a soil pH of 5.5 to 6.8.

Varieties

Radishes can be grown for spring or winter crops. Spring varieties are the common small red varieties. Winter radishes are larger, oblong, and can grow 8 to 9 inches long.

Spring Crops:

  • Cherry Belle – 22 days.
  • Burpee White – 25 days.

Winter Crops:

  • Black Spanish – 55 days.
  • White Chinese – 60 days.

Harvesting

Spring radishes require 20 to 30 days to reach harvest. Winter radishes require 50 to 60 days to reach harvest. Radishes are ready for harvest when roots reach 1 inch across. Lift the whole plant when radishes are the right size. Lift a few or push the soil aside gently to decide if they are large enough to harvest. Do not leave radishes in the ground too long or they will become pithy.

Water & Feeding

Keep radish planting beds moist but not wet. Even, regular watering will result in quick growth. Radishes that receive too little water will become woody tasting. Prepare planting beds with aged compost. Side dress radishes with aged compost at mid season.
