Identification and Diagnostic Services
Due to COVID-19 our office is open to the public, but appointment based visits. To schedule an appointment, please contact us at 208-287-5900. At this time, we are not accepting physical plant samples at our office. Please continue submitting your gardening questions, plant problems and plant or weed identifications via email. Please fill out the appropriate forms below. Email the forms with pictures (if appropriate) to firstname.lastname@example.org. If you are unable to email the form back to us, please send us an email with as much information from the form as possible. Realize that identifying plant problems, weeds and insects from pictures is difficult if the pictures are not clear. We need close-up shots as well as farther away pictures to see the entire plant. For insects, please position a penny next to the insect to give us some scale. We will do our best.
Our seasonal hours:
- May-August: 9 a.m. to 3 p.m.
Please drop off your sample and form at the office, and someone will get back to you.
Submitting Samples for Problems or Identification
Bring a branch approximately 12-18" long showing the progression of the problem. If the problem is on the trunk, bring clear pictures. Fill out the Plant Problem Form (PDF). Please bring the completed form and your sample into the office. No fee.
Bring a 12" square section from the problem area (showing a portion of the healthy & unhealthy conditions), including 2-3" of soil. Fill out the Plant Problem Form (PDF). Please bring the completed form and your sample into the office. No fee.
