Established in 1981, Colony Supply Center began as a provider of nursery supplies and a variety of quality mulches and soils to landscapers in Montgomery County, Maryland.

We proudly served our customers from our River Road location for over 32 years and for 10 more years from our Beallsville location. In 2024 we relocated to Clarksburg, MD, in collaboration with Metro Ground Covers and Grant County Mulch, Inc., the largest mulch and soil provider in the country.

We continue to provide delivery of quality bulk mulch, topsoil and compost to a variety of locations across Montgomery and Frederick counties in Maryland, maintaining the exceptional service you've come to expect from us for over 43 years.
