How to grow Radish 'Crimson Giant'

  • Full Sun

  • Medium

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

Position in a full sun location and remember to water moderately. Keep in mind when planting that Crimson Giant is thought of as tender, so it is really important to ensure that the outside temperature is well above freezing before planting or moving outdoors. Crimson Giant requires a loamy, clay and sandy soil with a ph of 5.5 - 6.8 - it grows best in weakly acidic soil.

Growing Crimson Giant from seed

Look to ensure a distance 0.98 inches (2.5 cm) between seeds when sowing - bury at a depth of at least 0.47 inches (1.2 cm) deep. Soil temperature should be kept higher than 13°C / 55°F to ensure good germination.

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

Transplanting Crimson Giant

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.

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Crimson Giant is a tender plant.

Harvesting Crimson Giant

This variety produces four to five inch round roots.

Expect harvests to start to occur in early spring.
