Climate in Colorado: What Growers Need to Know
Colorado’s growing environment presents unique challenges:
- Hot, dry summers with intense sunlight
- Cold, snowy winters and early frosts at high elevations
- Large fluctuations between day and night temperatures
- Low humidity, especially in the mountains and high plains
Best Time to Grow Outdoors
- Outdoor season: Late May to early September
