Regina Climate Notes

Black plastic mulch warms soil 2-4°C and extends the effective season. Wind-resistant varieties and windbreak planting are standard practice for serious Regina gardeners.
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 Regina
Pair pea with Carrot, Radish, Cucumber, Corn for mutual benefit. Avoid planting near Onion, Garlic, Chive, which compete with or inhibit pea growth.
