Frenchglen, OR frost dates
Gardening where frost is possible all year
The weather station nearest Frenchglen, OR records freezing temperatures in every month often enough that NOAA cannot define a frost-free season. Gardening is still possible — it just means planning for frost at any time:
- Grow fast, cold-tolerant crops: Radishes, Lettuce, Spinach, Kale, Peas, Potatoes, Swiss Chard, Garlic.
- Plant once the soil can be worked — usually late spring to early summer at high elevation — and keep row covers ready for clear, still nights.
- Use season extension: cold frames, low tunnels, wall-of-water cloches or a greenhouse turn a few frost-free weeks into a real season.
- Frost-tender crops (tomatoes, squash, beans) need protection all season; choose the earliest varieties you can find.
