When to Plant in Aurora, CO

Aurora, Colorado, experiences its last spring frost around May 17 and the first fall frost approximately September 27, resulting in a total of 133 frost-free days. This means gardeners have a relatively short growing season, making it essential to choose the right crops that can thrive within these constraints. To maximize the growing period, careful planning is crucial, particularly in understanding the local climate’s nuances.

The microclimate of Aurora is characterized as continental mountain, which brings cold nights and intense sun exposure during the day. This unique combination benefits certain crops such as tomatoes, peppers, and squash, which love the high altitude and long days; their growth is often vigorous in these conditions.
