Q.On-Site Advice
Is there anyone in Garrett County, Maryland who can assist me in designing my backyard garden area, and what would the cost be for such assistance? I’ve done a lot of research and have some basic ideas but would welcome an expert’s opinion.

I would recommend contacting your local extension office (you can look it up here:https://www.gardeningknowhow.com/extension-search/ and asking for information on Master Gardener's in your area. These groups are normally very happy to recommend a gardening coach or adviser to help you with your garden. Cost may vary. Some Master Gardeners are happy to provide services for free, while others ask for a small fee for their time. It should not cost very much if it costs anything at all.
