Planting Schedule

Add Turnip to your garden to build a schedule and get reminders.

Silky-smooth and sweetly mild, Turnip forms a crisp, tender flesh with a clean, refreshing bite that feels luminous from the first forkful to the last.

At about 45 days, the roots swell into a neat, table-ready shape—uniform, quick to mature, and wonderfully suited to fresh salads, roasting, and quick pickling for bright, tangy contrast. Grow Turnip for a cool-season harvest that delivers both delicate flavor and satisfying crunch in every bunch.

Culinary Notes


Chef's Note

Table turnips hit that rare spot where they taste sweet without going starchy—crunch stays crisp in salads and turns into caramelized edges when roasted. Use vinegar and mustard to sharpen the bite, or dairy to turn their clean brassica note into something silky and comforting.

Best Uses

  • shaved or thin-sliced raw salads with a sharp vinaigrette
  • roasted wedges with browned edges and buttery sweetness
  • quick pickling for bright, tangy crunch
  • creamed turnip or purée-style mash for smooth comfort

Frequently Asked Questions


What pest or disease commonly affects Brassica rapa (turnip) and how do I control it?
Turnips are often hit by flea beetles, which create tiny shot holes in leaves, and that leaf damage can stunt root development. Cover seedlings with floating row cover immediately after sowing and keep it on until the plants are well established; for heavier pressure, remove the worst-affected leaves and use an insecticidal soap on the undersides of leaves in the cool part of the day. Watch also for clubroot (galling/swelling on roots) and avoid planting Brassica rapa in the same bed for several years if you see symptoms.
How often should I water Brassica rapa during the main growing phase for best root size?
During bulking (after plants have formed a few true leaves), keep the soil evenly moist with about 1 inch (2.5 cm) of water per week, adjusting for heat and rainfall so the soil doesn’t dry out completely between waterings. Mulch lightly after roots start swelling to reduce moisture swings; inconsistent watering can lead to cracked, woody, or pithy roots.
How can I tell when turnips (Brassica rapa) are ready to harvest?
Harvest baby turnips at roughly 35–45 days when roots are about 1–2 inches (2.5–5 cm) across and the tops are still tender. For larger roots, harvest near the full 45-day window when the diameter reaches about 3 inches (7–8 cm), before they become tough and strong-flavored. If you can see the root shoulders at the soil line, you can lift one to check size and texture.
