Plant & Insect Diagnostic Services

How it Works:
Samples may be dropped off Monday through Thursday 8:00 am to 4:30 pm. Turf samples not accepted October – April. Horticulture staff will complete the analysis, confirm results and ensure that you are contacted with up-to-date research-based information on each sample.
