When to Plant in Ogden, UT

In Ogden, the gardening season is defined by a median last spring frost date of May 6 and a median first fall frost date of October 11, providing gardeners with approximately 158 frost-free days each year. This timeframe is crucial for planning what crops to plant, as it dictates when seedlings can be safely transferred outdoors and when to begin preparations for the colder months ahead.

The microclimate in Ogden is classified as continental mountain, characterized by cold nights and intense sun. This unique combination allows for excellent growth of crops such as tomatoes, peppers, and corn, which appreciate the warmth during the day, while the cool nights prevent excessive heat stress. However, crops like lettuce and spinach can struggle with the intense sun and fluctuating temperatures, often bolting prematurely as the days heat up.
