Johnson’s Landscaping Service traces its origins to the Johnson’s Flower and Garden Centers of Washington, D.C. and suburban Maryland, first founded in 1933 by Raymond Johnson, Sr. Raymond Johnson’s youngest son, Jim, opened Johnson’s Landscaping Service in 1960. Since that time, Johnson’s Landscaping has provided quality service to the communities of Northwest D.C., Bethesda, Chevy Chase, Kensington, Silver Spring, Rockville, Potomac, and Olney. As a testament to our many years of success, the majority of our business comes from client referrals and past customers.
