Utah is regularly subjected to extreme and unpredictable weather such as:
- Severe wildfires

Challenges of Growing in Utah
Despite the slightly extended growing season for the region, there are many challenges to gardening in Utah.
1. Unpredictable Weather
The weather across the state is unpredictable and can be severe. Wildfires, thunderstorms, landslides, winds, and more make the region a complete wildcard when it comes to monitoring weather. This, in turn, makes it difficult to track changes and know when to protect your garden.
2. Extreme Temperature Fluctuations
Between the high altitude climate and the desert and mountainous regions, the temperature fluctuates quite dramatically across the state. While daytime temperatures can be warm, nighttime temperatures can plummet and damage all of your hard work.
3. Dry Climate
Utah is no stranger to droughts. The climate across the entire state is very dry, with minimal precipitation throughout the year. Lack of moisture can be detrimental to most plants’ growth, making this a difficult challenge to overcome with outdoor growing.
