Insect and Plant Samples

If you are able to bring us a plant sample, it will make it much easier for us to provide you with a diagnosis of your problem. To take a plant sample, it is most helpful to bring a branch with multiple leaves.  If the plant is flowering, bring a branch with a flower. There is no charge for plant samples brought to Montgomery County Master Gardeners, whereas other entities may charge for diagnosis.

Sample Branch with Multiple Leaves

After you have selected your plant or insect sample, choose the most appropriate
form from the list below, and fill it out. Be sure to bring your plant or insect sample together with your form from below, when you come to the Plant Clinic.
