Regina Climate Notes

Black plastic mulch warms soil 2-4°C and extends the effective season. Wind-resistant varieties and windbreak planting are standard practice for serious Regina gardeners.
Growing Tips for Turnips
- Thin seedlings to 4-inch spacing when plants are 3 inches tall — crowded turnips produce small woody roots.
- Both roots AND greens are edible — harvest baby turnip greens 4 weeks after sowing, roots 5–9 weeks.
- Fall turnips are sweetest — plant 8 weeks before first frost and let cold weather convert starches to sugars.
- Succession plant every 2–3 weeks for continuous harvest through spring; skip summer heat and resume in fall.
Companion Planting in Regina
Pair turnip with Pea, Mint, Rosemary, Thyme for mutual benefit. Avoid planting near Potato, Radish, which compete with or inhibit turnip growth.
