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 Broccoli
- For spring: start indoors 6 weeks before last frost and transplant outdoors 4 weeks before last frost.
- For fall: start indoors in summer — count 10 weeks back from your first fall frost date.
- Harvest heads before any yellow flowers open — once flowers show, flavor declines quickly.
- After cutting the main head, leave the plant in — side shoots produce small florets for weeks.
Companion Planting in Vancouver
Pair broccoli with Onion, Garlic, Dill, Rosemary for mutual benefit. Avoid planting near Tomato, Pepper, Strawberry, which compete with or inhibit broccoli growth.
