Landscaping Services in St. Mary's County, MD

St. Mary's County is home for Sunscape. Our crews live and work here, and we've spent years learning what thrives on these properties and what doesn't. In a single week we might rebuild a patio at a Leonardtown home with a century of history behind it, refresh the yard at a Lexington Park rental between tenants, and plant a salt-tolerant border for a waterfront home on St. George Island.

Owner Tony Rosales built Sunscape around one idea: honest, hardworking local service. That means one team for design, construction, planting, and maintenance, and people who answer the phone when you call.

Our St. Mary's County Landscaping Services

A Peninsula County Means Waterfront Rules

St. Mary's County is almost surrounded by water, with shoreline along the Potomac, the Patuxent, the Chesapeake Bay, and creeks like St. Clement's, Breton Bay, the St. Mary's River, and Smith Creek. As a result, a large share of homes sit within 1,000 feet of tidal water, inside Maryland's Chesapeake Bay Critical Area. That can affect tree clearing, how much new patio or walkway you can add, and what replacement plantings may be required.

We design with those considerations from the start, favoring native and salt-tolerant plants, permeable surfaces where they make sense, and buffers that protect the shoreline. For larger projects, confirm your lot's requirements with St. Mary's County Land Use & Growth Management.

Caring for Historic Properties

From downtown Leonardtown to the countryside around St. Mary's City, the county has older homes with mature trees, brick walks, and established gardens. These properties call for a lighter touch: protecting old root zones, matching traditional materials, and choosing plants that complement the home's character instead of competing with it.

Can you maintain my yard while I'm deployed or after I PCS?

Yes. We offer recurring lawn care and seasonal maintenance for homeowners who are away, as well as one-time cleanups to get a home ready for sale, a new tenant, or a final inspection. We can coordinate details by phone or email so you don't need to be on site.

Does the Chesapeake Bay Critical Area affect my St. Mary's County project?

If your property is within 1,000 feet of tidal water or tidal wetlands, it likely does, and that covers many homes in this peninsula county. The Critical Area can limit clearing and new impervious surfaces and may require replacement plantings. We plan around these rules and recommend confirming your lot's requirements with St. Mary's County Land Use & Growth Management.

What plants hold up best near the water in St. Mary's County?

Native, salt-tolerant plants generally perform best on waterfront lots. Good choices often include bayberry, inkberry holly, switchgrass, little bluestem, and seaside goldenrod. They handle wind and salt spray, need less watering once established, and help protect the shoreline.

When should I schedule fall lawn work?

September through October is the best window for seeding and overseeding cool-season lawns like tall fescue in Southern Maryland. Plan fertilizing accordingly, since Maryland law prohibits applying lawn fertilizer between November 15 and March 1.

How much does landscaping cost in St. Mary's County?

Most residential projects range from around $500 for seasonal maintenance to $10,000 or more for custom hardscapes like patios, retaining walls, and fire pits. Every St. Mary's County estimate is free, on-site, and itemized.
