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 Swiss Chard
- Each chard 'seed' is a multi-seed cluster — thin to 8-inch spacing or transplant extras for full plants.
- Harvest outer stalks when they reach 8–10 inches; the plant produces continuously for 4–6 months.
- Chard tolerates part shade better than most leafy greens — good for shaded corners of the garden.
- In Zones 6+ Swiss chard often overwinters with light mulch and produces early spring leaves before bolting.
Companion Planting in Vancouver
Pair swiss chard with Bean, Onion, Cabbage, Kohlrabi for mutual benefit. Avoid planting near Cucumber, Melon, which compete with or inhibit swiss chard growth.
