Compost: healthy soil retains more water.

  

Adding compost helps soils retain more water

Prevent the need to water more by choosing natural yard care products and compost with lots of organic material that helps the soil absorb and hold water.

It's best to pick a compost that comes from a recycled waste stream, such as composted yard waste or Groco biosolids. Using these products keeps them from going to a landfill.

Did you know? Each pound of waste that doesn't go into the landfill prevents 2.5 pounds of CO2 emissions.
