We're here to help! The Master Gardener Volunteer Helpline serves Vermont residents by providing science based information about home horticulture issues and integrated pest management (IPM). Unfortunately, Master Gardener Volunteers cannot provide personal site visits to home gardens. Volunteers are also limited on the pesticides they are allowed to recommend as they are not licensed pesticide applicators. Note: Commercial Growers, please scroll down the page to the Commercial Growers dropdown menu. Do not submit your question using the form below.

How to Submit Specimens
