Alpine (F1) Radish Seed

Item #HSC-RAD-001-PKT

A traditional Korean radish for kimchi.

Alpine is the type most often grown for kimchi in Korea. Its smooth 5–8" × 2–2½" roots are white with green shoulders and sweeter than long white Japanese daikon.

It copes better with rocky soil than long types and keeps its flavor in warm weather. Bolt tolerance allows spring and summer sowings; use it fresh, pickled, fermented or stored.

About 55 days from sowing. F1 hybrid.

Growing guide

From seed to harvest

Mind the season

Sow in the season given for each variety to avoid bolting.

Loosen deeply

Deep, loose soil or raised beds give straight, easy-to-dig roots.

Thin to 4–6"

Sow 10 seeds per foot, rows 18" apart, and thin.

Lift with care

Fork the roots out, trim tops to 2" and store at 32°F for 6–10 weeks.

Growing Information

Scientific name

Raphanus sativus var. longipinnatus

Growing conditions

Daikon, Korean and other specialty radishes need loose, well-drained soil at pH 5.8–6.8. Long-rooted types grow straighter and are easier to dig if you loosen the soil deeply, ideally in raised beds. Check the recommended sowing season in each variety description, since sowing at the wrong time can make plants bolt.

Days to maturity

Counted from direct sowing.

Direct sowing

Sow about 10 seeds per foot in rows 18" apart, then thin to one plant every 4–6".

Seeding rate

In rows 18" apart: about 1 oz. per 260 ft., 3.9 oz. per 1,000 ft. and 7 lb. per acre.

Harvest

Loosen the soil alongside the roots with a fork or undercut them before lifting, so the long roots do not snap.

Storage

Trim the tops to 2" above the crown, wash and refrigerate. Roots keep 6–10 weeks at 32°F (0°C) and 95% relative humidity.

Seed

Seed for these types is not sized.

Packet

100 seeds.

Seeds per lb.

About 40,200 on average.
