Turnips - Key Growing Information
SCIENTIFIC NAME: Brassica rapa
CULTURE: Turnips are tolerant of moderate frost as seedlings in spring, and as mature plants in fall. Turnips prefer a fertile, well-drained soil, with a pH of 6.0-7.5. Sow early spring through late summer in a 2-4" wide band, seeds 1" apart (35 seeds/ft.) for small turnips or 2" apart and half this rate for larger turnips. Sow 1/4- 1/2" deep in rows 12-18" apart.
INSECT PESTS: Floating row covers installed at the time of sowing will keep the turnips free of insect pests, including flea beetles and root maggots.
HARVEST: Young, radish-size turnips in about 30 days, full size in 40-50 days. Roots are smoothest when small.
STORAGE: Turnips with greens store at 32°F (0°C) and 95% relative humidity for 10-14 days. Not intended for long-term winter storage.
