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 Collard Greens
- Harvest outer leaves continuously once plants reach 10 inches — the central growing point produces for months.
- In Zones 8+ collard greens often overwinter and produce for 2–3 years as a perennial.
- Frost improves flavor dramatically — southern tradition is to wait for the first frost before harvesting.
- Blanch and freeze excess harvest — collard greens freeze beautifully and provide winter vitamins.
