Tanacross, AK frost dates

Gardening where frost is possible all year

The weather station nearest Tanacross, AK 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.
