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 Green Beans
- Direct sow only — beans do not transplant successfully.
- Succession plant every 2–3 weeks for continuous harvest throughout the season.
- Do not over-fertilize with nitrogen — beans fix their own nitrogen from the soil.
- Harvest every 2 days at finger-length; leaving beans on the vine signals the plant to stop producing.
