Plant Diagnostic Clinic
Jefferson County Extension has an on-site walk-in plant diagnostic clinic staffed by trained personnel in plant forensics, plant, insect and landscape weed identification. Before bringing a sample to the clinic, check this link for instructions on the type of sample to collect.
Samples may be dropped off anytime during normal business hours: 8 am to 5 pm, Monday through Friday. We try to complete your diagnosis within 3 business days. Fees apply.
Demonstration and Research Gardens
Our two on-site gardens are open to the public. The Plant Select garden offers beautiful displays of water-wise and climate tested plants. There’s a kiosk in the garden containing information on the plants and their growing requirements.
The Horticulture Research and Demonstration Garden contains on-going studies including blueberry production, apple tree training, tomato and pepper variety trials and innovative vegetable garden season extension tools. We are also developing an insectary garden to attract beneficial insects.
