Growing Turnips in West Palm Beach
West Palm Beach sits in Zone 10a, with an average last frost of Frost-free and first fall frost around Frost-free — giving a 365-day frost-free growing season. Cool-season crops like turnip benefit from West Palm Beach's cooler spring and fall windows, when temperatures stay in the 55–75°F sweet spot that produces the best flavor and least bolting.

Wet season rains drive fungal disease fast enough to destroy an unprotected crop within a few weeks. Plan main plantings for dry season and keep beds well-drained.
West Palm Beach's sandy soils drain fast — West Palm Beach gardeners should water turnip more frequently (every 2 to 3 days during peak summer) and add generous compost to improve moisture retention.
