NOTICE:

As of January 2023, Colorado State University Extension (CSUE) in Jefferson County has closed its on-site Plant Diagnostic Laboratory in order to align with Colorado State University’s (CSU) state diagnostic processes.

CSUE Jefferson County’s Horticulture team will continue to have a Plant Diagnostic Help Desk, that will perform sample intake and diagnostic assessments for local residents. However, any commercial samples or samples requiring further diagnosis or laboratory work will now be sent to CSU’s Statewide Plant Diagnostic Clinic, found at the CSU SPUR campus.

To send samples directly to CSU’s Plant Diagnostic Clinic, you can visit their webpage for instructions, or you can contact them directly:
