Brassica rapa subsp. rapa
vegetableFast-growing, peppery greens harvested from turnip plants before — or alongside — the roots. One of the most nutritious cool-season greens available, widely eaten in the American South, Italian cooking (cime di rapa), and Asian cuisines. Young leaves are tender enough for salads; older leaves are best braised or sauteed with garlic and olive oil.

When to Fertilize
Light balanced fertilizer at planting; nitrogen side-dress if growing large plants
Fertilizer
Balanced granular at low rate; compost amendment in soil before planting
Direct sow 4 to 6 weeks before last frost, or start a fall crop 6 to 8 weeks before first frost. For greens only, sow thickly and skip thinning. For roots and greens together, thin to 4 inches. Cool weather produces the sweetest, most tender leaves. Leaves become tougher and more pungent in heat. A fast crop — baby leaves are ready in 30 to 40 days.

Row cover from sowing; diatomaceous earth around seedlings; succession-sow to replace damaged plants
Bt spray at early caterpillar stage; row cover; inspect weekly
Water blast; insecticidal soap; plant alliums nearby
Row cover; crop rotation; avoid fresh manure at planting
For baby salad greens: harvest at 2 to 4 inches, about 25 to 30 days from sowing. For cooking greens: harvest outer leaves from 4 to 8 inches tall plants. Young leaves are best raw or lightly wilted. Older leaves over 10 inches are better braised. Refrigerate and use within 4 to 5 days — turnip greens wilt faster than kale or collards.
Exceptional nutritional density: very high in vitamins A, C, K, and folate. One of the highest-calcium greens available — similar to kale. Contains glucosinolates with cancer-protective properties. The combination of turnip roots and greens provides complete nutrition from a single plant.
