Zone 3

Zone 3 is the coldest and shortest of the USDA garden zones.

With a last frost date around late May and a first frost date around mid-September, the frost-free growing season is from early June to early September. These dates are general guidelines, so watch the weather forecasts before planting. 

With a short season and an average minimum temperature of -30°F, choosing shorter season varieties and starting seedlings inside is a must. 

Scroll down to see the vegetable planting guide. The orange color shows when to start seedlings indoors, the yellow is times to transplant or direct sow and the green is harvest dates.
