Halifax Climate Notes
Halifax's Atlantic climate is cool and damp. Choose blight-resistant tomato varieties (Defiant, Legend, Iron Lady) — late blight is common in the humid Atlantic summer. Kale, chard, and brassicas thrive in the maritime climate. Sea fog in May-June delays spring by 2-3 weeks compared to inland Ontario at the same latitude.
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 Halifax
Pair turnip with Pea, Mint, Rosemary, Thyme for mutual benefit. Avoid planting near Potato, Radish, which compete with or inhibit turnip growth.
