Ask a Master Gardener (In Person!)


Harford County Master Gardeners hold free Plant Clinics on Saturday mornings on a rotating basis. Master Gardeners are on hand to give gardening advice and troubleshoot gardening problems - including plant identification and diagnostics, insect identification and management, recommendations for plant selections, and much more.  Bring in samples of your problem plants or insects and we will help find an answer for you.
