Growing Turnips

Turnips offer two harvests from one sowing: leaves early and roots later. That flexibility makes them useful when the fall window is real but not generous.

Sowing and thinning

Direct sow into a fine, evenly moist seedbed. Thin promptly: crowded seedlings can supply a small greens harvest, but roots need individual space to swell. Cut extras at soil level when pulling would disturb neighboring roots.

Water and quality

Steady moisture supports tender roots. Drought, heat, and delayed harvest can make roots woody or strongly flavored. Small roots are often the best roots; do not wait for maximum size simply because the crop can keep growing.

Use the whole crop

Harvest a few leaves without stripping a plant completely, or grow a dense section specifically for greens. Protect young foliage from flea beetles and cabbage-family caterpillars where those pests are active.

Record whether the sowing was intended for greens, roots, or both. Note thinning date, root size at best texture, and how the first hard frost changed flavor.
