Growing Turnips: A Complete Profile

By Growing Home Greens Team · July 18, 2026

Turnips are an underused fast crop — direct-sown, no transplanting fuss, and ready to eat in under two months. They’re an easy way to fill a bed gap between slower-growing neighbors.

What to expect

Direct-sow turnip seed a few weeks before your last frost; it germinates in cool soil and doesn’t need the head start that slower crops do. At 9 plants per square foot and 50 days to maturity, a single sowing gives you a quick, dense harvest — good reason to succession-sow every few weeks if you want a steady supply instead of one big flush.

Common problems

Woody or overly sharp-tasting roots almost always mean they sat in the ground too long — turnips are best pulled small and eaten young rather than left to bulk up. Like other fast brassicas, they’re prone to flea beetle damage on young leaves; row cover at seeding time heads this off before it starts.

Where this fits in your garden

Turnips pair well with peas, which fix nitrogen that benefits neighboring root crops — see the full companion guide for turnip. Their short season and high density make them a good “gap filler” in the Garden Designer: sow them into a square that a spring crop just vacated, and they’ll be done before whatever comes next needs the space.
