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 Lettuce
- Direct sow very shallowly — lettuce seeds need light to germinate; cover with just 1/8 inch of soil.
- Cut outer leaves 1 inch above the crown for "cut-and-come-again" harvests lasting weeks.
- Provide afternoon shade in warmer climates (Zones 7+) to extend the spring window before heat bolts plants.
- Fall lettuce is often better than spring — plants mature as temperatures cool, producing sweeter, crunchier heads.
Companion Planting in Vancouver
Pair lettuce with Carrot, Radish, Strawberry, Chive for mutual benefit. Avoid planting near Fennel, Celery, which compete with or inhibit lettuce growth.
Pests and Problems to Watch in Vancouver
