Daikon Radish
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.

🌱 Growing Guide
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.

🌾 Harvest & storage
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.
🥗 Nutrition & benefits
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.
