Gardening Help

Have a gardening question? We’ve got the answer! Contact Colorado Master Gardeners at gardeninghelp@botanicgardens.org. They can also answer any plant-related questions and offer ornamental or cultivated plant identification. Following directives from CSU to protect the health of the public and our volunteers, Colorado Master Gardeners are only answering questions submitted by email for the time being.

For over 10 years Denver Botanic Gardens and Colorado State University (CSU) Extension Colorado Master Gardeners have collaborated to provide help to home gardeners. Colorado Master Gardeners tap into the knowledge of the Gardens and CSU Extension to provide sound scientific research-based horticulture information that is applicable to our diverse and sometimes challenging Colorado climate.
