Saskatoon Climate Notes
Saskatoon averages only 350 mm of annual rainfall — irrigation is essential for most vegetables. Prairie soil is rich and black with excellent fertility but compacts easily. Extended midsummer daylight (16+ hours) partially compensates for the short season; Saskatchewan peas and root vegetables are legendary for quality.
Growing Tips for Peas
- Soak pea seeds overnight before planting to speed germination in cool soil.
- Install a 4–6 foot trellis at planting time — peas climb from day one and produce more per square foot when supported.
- Sow every 2 weeks through early spring for a continuous 6-week harvest window.
- Plant a second crop 10–12 weeks before first fall frost for autumn harvests; shade cloth helps germination in warm soil.
Companion Planting in Saskatoon
Pair pea with Carrot, Radish, Cucumber, Corn for mutual benefit. Avoid planting near Onion, Garlic, Chive, which compete with or inhibit pea growth.
Pests and Problems to Watch in Saskatoon
The most common pest and disease pressure on peas in Saskatoon comes from Pea Aphid, Powdery Mildew, Root Rot, Pea Weevil. 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.
