Vancouver Climate Notes
Vancouver is Canada's gardening capital. Year-round growing is possible for hardy crops. Tomatoes need warm, sheltered spots or polytunnels for reliable ripening because summer nights are often cool. Slugs and powdery mildew are primary pest and disease challenges. Fall planting for winter harvest is a signature Vancouver technique that has no equivalent elsewhere in Canada.
Growing Tips for Potatoes
- Cut seed potatoes into 2-inch chunks with at least two eyes each, then let cut surfaces heal for 24–48 hours before planting.
- Plant 4 inches deep and 12 inches apart in loose, well-drained soil; add compost but avoid fresh manure.
- Hill up soil around stems when plants reach 6 inches tall to cover developing tubers and prevent green potatoes.
- Stop watering when foliage yellows; let skins toughen for 1–2 weeks before digging for better storage.
