When To Transplant Radish Seedlings

  • Start radishes from seed sown directly in the garden.
  • Seed is viable for 5 years.
  • Start seeds in the garden about 6 to 4 weeks before you expect the last frost in spring.
  • If started indoors and transplanted, allow two additional weeks to maturity as a result of root insult at transplanting; nip off the long thread tip of the radish root when
  • Sow seed ¼ to ½ (6-12 mm) inch deep and be sure to heel or stamp the soil firmly.
  • Sow seed 1 inch (2.5 cm) apart and later thin to 4 inches (10 cm) in all directions.
  • To improve germination sow seed at dusk or on a cool, cloudy day.
  • Sow seed in loose, fertile soil. Adding aged compost to planting beds in advance of sowing will feed the soil and aide moisture retention.
  • Seeds should germinate in 4 to 10 days at an optimal temperature of 70°F (21C) or greater; germination will take longer in colder soil.
  • Optimum soil temperature to grow radishes is 50° to 75°F (10-24°C).
  • Make additional sowing at 3-week intervals for a continuous harvest, but time sowing so that crop does not mature in hot weather.
  • Radishes prefer a soil pH range of 5.5 to 6.5.
  • Grow radishes in full sun for best yield—tolerates partial shade.
  • Fertilize with an organic fertilizer such as fish emulsion at half strength.
  • Common pest enemies are aphids, flea beetles, and cabbage root maggots, cabbage worms, cabbage loopers, and wireworms.
  • How big should radish seedlings be before transplanting?

    To solve any little space issues, you can thin your radishes and then replant them. Ideally, radishes should be about an inch apart, so look for ones that are too close together and then pick one of those to remove and replant.

    When should radishes be transplanted?

    Radishes planted in the late summer are ready to harvest 50 and 70 days after planting. If during this time you must transplant your radishes -- perhaps because they are not getting enough sunlight or want to plant something else in their place -- then do so carefully so you don't damage your plants in the process.

    Do you need to thin radish seedlings?

    It's important to thin the seedlings before the roots become fleshy, often before the the plants get their second set of leaves. If you don't thin your seedlings and the roots grow too close together, the plants can become stunted and the roots will be small and distorted.

    How do you transplant radishes?

  • Cover the entire cut surface of the radish root in germination gel.
  • Dig a hole 2 inches in the soil using a garden hoe.
  • Dig a row of holes 2 inches apart from each other.
  • Store the other radishes for future use.
  • Can I grow radishes in seed trays?

    Sowing Radishes Early into Plug Trays

    Begin sowing under cover from late winter, either direct into containers of potting soil or into greenhouse borders, or into plug trays of general purpose potting mix. Fill plug trays with potting mix, firm down then sow a pinch of three to five seeds per module.

    Why are radish seedlings leggy?

    Radishes will grow long and thin in response to hot weather, unsuitable soil, and competition with other plants. Too much nitrogen in the soil may also cause radishes to grow long and thin.

    How deep does the soil need to be to grow radishes?

    Plant radish seeds from early April through early May for a spring crop, and again August 1 through September 1 for a fall crop. Allow about one inch between seeds in the row. Plant the seed of smaller varieties shallowly, one-fourth to one-half inch deep. Plant larger varieties deeper, up to one inch deep.
