Note: Before you come in, please review our plant diagnosis questions to gather information that will let us better assist you.
Bringing in samples
- Monday through Wednesday are the best days to bring a sample in, in case we need to send it out for further analysis.
- Samples with live insects should be placed in a sealed container, such as a glass jar or plastic bag.
- Bring enough plant material to work with for diagnosis which means including both healthy and unhealthy tissue.
- Bring recent samples, not old, dried out material.
- Please do NOT include wet paper towels in bags with plant samples.
