Provide us with a good representative sample of the weed you are concerned about. Samples that include flowers or fruit are essential for positive identification. Drop the sample off at the weed office or email us a photo. From there we will begin the process to provide you with more information and resources about the plant of concern.

Poisonous Plants

Give us a call right away! Have the plant in question on hand to help with the identification. Providing a plant sample and/or arranging for a site visit will likely be needed for confirmation.
