Daikon Minowase Radish Seeds

Sow Minowase Daikon Radish seeds directly outdoors, since this variety does not transplant well, so there is no point starting it indoors. As soon as the soil can be worked in spring, push seeds ¼ inch deep and space them 4–6 inches apart. Daikon Minowase Radish seeds germinate in 7–10 days at soil temperatures between 50–65°F. Thin seedlings early, because crowded plants develop forked roots and lose their appeal. For a steady supply through the season, succession sow every 2–3 weeks rather than putting everything in the ground at once.

Full sun is needed, at least 6 hours daily. Minowase Daikon Radish roots grow up to 24 inches long, and they need deep, loose, stone-free ground to develop straight and clean roots. Work the soil to at least 12–15 inches before sowing and pull out any rocks or compacted clumps. Rocky or hard ground does not stop the root from growing; it just forces it to fork around the obstacle, which ruins the yield. Water consistently throughout the growing season, but make sure your soil drains well, as waterlogged roots can rot. Hold back on nitrogen-heavy fertilizers, as excess nitrogen pushes leaf growth at the expense of roots.

Daikon Radish Minowase is a cool-weather crop and grows best in spring and fall. Summer heat pushes causes bolting before roots size up properly. Beyond thinning and watering, there is not much to manage, which makes it a good choice for gardeners who want results and don’t have much time to take care of plants. Harvest roots on time, because mature plants can become sharp and spongy in a day or two. In loose soil, pull by hand; in firmer ground, loosen around the root with a fork first to avoid snapping it.
