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

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.

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

Do not transplant.
