Soil & site
Any loose, average soil. Too much nitrogen grows lush tops and puny roots.
Seedling care
Direct sow only — radishes go seed to table faster than transplants would recover. Thin early.
Growing notes
Sow a short row every week or two instead of one big planting; they all mature at once otherwise.
Harvest
Pull promptly at size. Left too long they turn pithy and hot.
