Radish 'Crimson Crunch'

Once your radishes germinate, keep them watered as evenly as possible. Do not over water, but don’t let them dry out either.

Crimson Crunch likes a position of full sun and remember to water moderately. Crimson Crunch is generally regarded as a tender plant, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside. Crimson Crunch needs a loamy, clay and sandy soil with a ph of 5.5 to 6.8 (weakly acidic soil).

Try to aim for a seed spacing of at least 0.98 inches (2.5 cm) and sow at a depth of around 0.47 inches (1.2 cm). For optimal germination, soil temperature should be a minimum of 13°C / 55°F.

By our calculations, you should look at sowing Crimson Crunch about 28 days before your last frost date.

Do not transplant. Sow in stone-free soil in early spring to early summer, and again in late summer for fall crop (if desired). Thrives in cool weather. Make successive sowings every 2 weeks. The recommendation for most root radishes is to directly sow them 4 weeks prior to your last frost date. However, you can start sowing as soon as the ground has thawed and air temperatures are averaging over 40 degrees on most days. Depending on what your springs are like (short and fast, long and drawn out), these conditions may emerge much sooner than or much later than the 4 week guide might suggest. Don’t be afraid to experiment.

Crimson Crunch is tender, so ensure you wait until all danger of frost has passed in your area before considering planting outside.

This variety tends to mature and be ready for harvest in early spring.
