How to Grow Lots of Turnips from Seed to Harvest

About turnip

Turnips deliver tender roots and zesty greens fast for salads or stir-fries. Gardeners pick them young for mild crunch and double harvests.

Originating in Asia thousands of years ago, they love cool, sunny spots with rich soil. Brassica family ties link them to cabbage kin.

Indoors, pull roots in 35-60 days from deep pots. Steady moisture and sun yield ongoing picks for months.

Watering Schedule

Turnips demand even moisture for juicy roots. Water when top inch dries, roughly every 2-4 days.

Deep soak until drainage appears.
Use room-temp water always.
Mulch pots to retain even dampness.
Base water to dodge leaf fungi.
Ramp up in dry indoor air.
Ease off before harvest week.
Avoid Dry Spells
Uneven water splits roots or spurs woody growth.
