Bringing samples to the Master Gardener Office
For plant samples brought into the office:
The sample should be freshly acquired and just packaged in clear freezer bag--not put in a bag, left to mold for a week, and then brought in. Store in the refrigerator until you are able to bring it in.
A good size sample is required, showing leaves, bark, stem and flower, if applicable.
Try to have a section of "good" plant as well as the problem.
Write the name of the plant (if known) as well as your contact information on the bag.
For insect samples:
Do not tape an insect to a piece of paper. We can not identify insects that have been smashed, are missing body parts or that are incomplete. The best way to preserve insects in in alcohol. A container or jar with the insect inside will also work.
