Once your radishes germinate, keep them watered as evenly as possible.Plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Champion is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside. Use USDA Hardiness Zone 5 - 14 as your guideline for the appropriate climate for this plant. Champion requires a loamy, clay and sandy soil with a ph of 5.5 - 6.8 - it grows best in weakly acidic soil.
By our calculations, you should look at sowing Champion about 28 days before your last frost date.
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 °F / 4 °C 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 Champion is a tender plant.
