Growing notes

What makes the difference in Northwest gardens, in plain language.

Soil and sowing

Turnips grow best in loose, well-drained soil with a pH of about 6.0 to 7.5. Mix in some compost, but avoid heavy nitrogen, which grows leaves instead of roots. Sow seeds directly, keep the soil moist until they sprout, and thin early so each plant has room. Crowded turnips stay small and lopsided. Steady watering keeps roots sweet and smooth; dry soil makes them hot and woody.

Spring vs fall, and why fall is sweeter

Turnips are a cool-season crop. In spring, warm weather and long days can make roots tough and plants bolt, so sow as early as the soil allows and pick young. Fall crops, sown in mid to late summer, mature as the weather cools, and a light frost turns some of their starches to sugar. West of the Cascades, fall turnips often hold in the ground into early winter. East of the Cascades, harvest before the soil freezes hard. Hakurei is a quick, mild salad turnip, while Purple Top White Globe is the classic for cooking and storage.

Root maggots, harvest and storage

Cabbage root maggots tunnel into turnips in cool, wet soil, leaving brown trails. Row cover laid on at sowing keeps the egg-laying flies away, and rotating where you plant cabbage-family crops helps too. Pull roots at 2 to 3 inches across for the most tender texture. Twist off the greens, which are good cooked, and store roots in a bag in the fridge for several weeks. Larger fall turnips can keep for months in a cold, damp root cellar.
