About this plant
Turnips provide rounded roots and edible greens in a compact planting. They suit all four zone groups (3-4, 5-6, 7-8, 9-10), as a cool-season annual and grow in full sun to partial shade.
Use loose, well-draining soil that allows roots to expand easily. Maintain consistent moisture for tender roots, checking the soil regularly rather than letting plants alternate between drought and soaking.
Common beginner failures and fixes
- Small roots in a crowded row: Thin seedlings using the spacing guidance on the seed packet.
- Woody roots left in the ground too long: Check roots as they enlarge and harvest while tender for the variety.
- Coarse roots after dry spells: Keep moisture consistent and mulch around established plants to slow drying.
- Tiny holes in young leaves: Protect seedlings with insect mesh and keep its edges secured against pests.
Beginner checklist
- Choose a turnip variety suited to your intended use.
- Plant during a locally suitable cool season.
- Provide full sun to partial shade and loose, well-draining soil.
- Thin seedlings and keep moisture consistent for tender roots.
- Inspect roots regularly and harvest before they become woody.
