Raphanus sativus var. longipinnatus
vegetableDaikon is a large, long, white Asian radish with mild, crisp, juicy flesh, used raw in salads, grated as a condiment, pickled, and simmered in soups and braises; its deep taproot also makes it a popular soil-loosening cover crop. Unlike quick spring radishes, it is grown as a longer-season fall crop, maturing in roughly 50 to 70 days.

When to Fertilize
Little needed; avoid excess nitrogen
Fertilizer
Low-nitrogen (5-10-10)
Direct sow in late summer for a fall crop into loose, deep, stone-free soil so the long roots grow straight, thinning to about 4 to 6 inches apart. Keep moisture even and steady, since interrupted growth makes radishes hot and pithy, and let the roots finish in cool weather for the sweetest, mildest flavor.

Sow in loose, stone-free soil and keep moisture even
Pull when roots reach full size, generally 50 to 70 days from sowing and before a hard freeze. Cool weather keeps the flavor mild and sweet, while roots left too long or grown dry turn pithy and sharp.
Daikon is very low in calories and a good source of vitamin C, with fiber, potassium, and calcium, and like other radishes it contains the antioxidant compounds behind its peppery bite.
