The Okanagan is Canada's wine and orchard country — equally excellent for heat-loving vegetables. Kelowna averages 40+ days above 30°C each summer, making it one of Canada's hottest growing climates. Drip irrigation and heavy mulch are essential to conserve water in the semi-arid climate.
Growing Tips for Beans
- Inoculate bean seeds with rhizobium bacteria before planting in new garden soil — boosts nitrogen fixation and yields.
- Plant bush beans every 2–3 weeks through midsummer for a continuous harvest from July to first frost.
- Pole beans produce for 6–8 weeks from a single planting; plant once, harvest all season.
- Never handle wet bean plants — working among wet foliage spreads bacterial diseases between plants.
