Sow at a depth of approx.
0.47 inches (1.2 cm) and aim for a distance of at least
0.98 inches (2.5 cm) between Radish plants. Soil temperature should be kept higher than
13°C / 55°F to ensure good germination.
By our calculations, you should look at sowing Burpee White about 28 days before your last frost date.
Ensure that temperatures are mild and all chance of frost has passed before planting out, as Burpee White is a half hardy plant.
