Lexington Park sits barely 115 feet above the tidewater, wedged between the Patuxent and the Chesapeake, and that low, salt air position shapes everything that grows here. The sandy loam left behind by this coastal plain drains fast and leaches nutrients just as fast, so compost rich topsoil and a steady mulch layer do more work here than fertilizer ever will. Yards near Naval Air Station Patuxent River and the older streets off Great Mills Road often need topsoil blended in before sod or beds will hold moisture. Newer construction in Wildewood and California tends to come with compacted subsoil scraped flat by grading crews, while waterfront lots in Chesapeake Ranch Estates fight shoreline runoff and shifting sand. With 43 inches of rain a year and Zone 8a warmth, decorative stone and river rock have become the go to fix for the swales and downspout lines that mulch simply washes out of.
