Compost ($23*/cubic yard - includes sales tax)

HoCoGro Compost is a soil amendment registered with the Maryland Department of Agriculture. It is regularly laboratory tested. Here are the latest lab results. Mixed into soil, compost adds nutrients, organic content and makes the soil more workable and retain moisture. These are all qualities that chemical fertilizers normally can't do.

Mulch ($21*/cubic yard - includes sales tax)

Naturally colored, double-ground mulch is excellent for top dressing your garden. Unlike some dyed mulches, this product will not steal nitrogen from your beds.

Topsoil Blend ($25*/cubic yard - includes sales tax)

A mix of soil and HoCoGro Compost makes this a fantastic growing mix for lawns and gardens. The compost addition makes it workable and able to retain moisture. Topsoil by definition is the top four inches of soil which includes the dark first inch and the often clay-like, pale remaining three inches. Our blended topsoil is dark and rich, but also cost-effective and available in bulk.

Estimating your needs

We sell our products by the cubic yard; they are loose and not bagged. A cubic yard is equivalent to about 9 large bags of mulch which typically each contain 3 cubic feet. A cubic yard of mulch, spread 2 inches thick will cover a 10'x15' area. There are many free online calculators that may be able to help you estimate your needs.


  • A truck with a 4 foot bed can hold 1/2 cubic yard
  • A truck with a 6 foot bed can hold 1 cubic yard
  • A truck with an 8 foot bed can hold 2 cubic yards
  • 1 cubic yard is roughly 173 gallons
  • A 1/2 cubic yard is 17 five-gallon buckets
  • Paper lawn bags are 30 gallons...1/4 cubic yard would be 1.5 bags filled full (45 gallons)

  • Pilot Compost Area

    The Bureau of Environmental Services has constructed a pilot compost project to produce quality compost. This state of the art pilot project is located on a ¾ acre site at the Alpha Ridge Landfill and is designed to compost yard trim and food scraps in aerated, covered piles. The facility started accepting material from the pilot curbside program in March 2013.

    Treated Wood

    Treated wood/lumber and railroad ties will be considered Construction & Demolition Debris and is not recyclable. Residents disposing of construction, demolition and home improvement material as trash will be directed to weigh in at the scalehouse and will be charged $80/ton ($4 per 100 pounds) of waste.
