Request a Site Visit

Commercial horticulture & HOA site visits

Who is eligible? Commercial/HOA site visits are for any commercially managed property including HOAs, parks, churches, businesses, etc. (not individual homeowner yards) and/or green industry clients with plant/landscape issues or questions.

For individual home owners, please see our Master Gardeners.

How commercial site visits work: A Boulder County horticulture agent will walk the property and assess overall landscape health and management. The agent will identify plants and weeds, look at irrigation issues and answer your specific questions. A $100.00 site visit fee will be due at time of visit. Site visits typically last 1-2 hours, depending on the size of the property. The agent will write up a comprehensive report detailing everything discussed during the visit and will include recommendations and resources.

Availability: Site visits are typically conducted during the growing season (April through October) but may be scheduled outside of this time period, if necessary.
