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 Spinach
- Direct sow in very cold soil — spinach germinates at 35°F, earlier than almost any other crop.
- Succession plant every 10 days until 2 weeks before heat sets in for continuous spring harvests.
- Switch to bolt-resistant varieties like Malabar or New Zealand spinach for summer heat (though technically different species).
- Fall spinach often overwinters in Zones 6+, producing the earliest harvest of the next spring under row cover.
Companion Planting in Vancouver
Pair spinach with Pea, Strawberry, Radish, Lettuce for mutual benefit. Avoid planting near Fennel, which compete with or inhibit spinach growth.
Pests and Problems to Watch in Vancouver
The most common pest and disease pressure on spinach in Vancouver comes from Leaf Miner, Aphid, Downy Mildew, Slugs. Floating row covers through the first 4–6 weeks after planting block adult pests from laying eggs, and a weekly scouting routine catches infestations before they damage the crop.
