Assistance by email:
You can email questions to Margaret at firstname.lastname@example.org or call her main office in Chippewa County at 715-726-7957.
Electronic photos are welcomed. For plants or plant disease, include information such as the species of plant, age and/or size, growing conditions, location in yard, and a brief description of the problem.
For insects, please indicate where it was found.
Please include your name, phone number and mailing address.
In office diagnosis:
You may stop in our office from 8:00 AM – 4:30 PM with your questions or plant or insect samples. If Margaret or a Master Gardener Volunteer is not available to help you then, we will have someone get back to you ASAP, usually with a day or two. Sometimes we may need a few days to find an answer, but we will find one for you!
Home site visits are not performed. Please contact a for-hire professional for on-site assistance.
- A non-chemical solution will be emphasized when appropriate and practical (which is most of the time!)
- To minimize chemical missuse and abuse, Master Gardener Volunteers have been instructed to NOT provide chemical recommendations over the phone or electronically to the general public. When necessary, a fact sheet can be mailed to the homeowner with a variety of control recommendations.
- To receive a chemical recommendation, samples can be delivered to the office to be examined by the Master Gardener Volunteers. Appropriate recommendations are given only once a visual diagnosis is made.
