How to Use Sand & Peat Moss in Cement Containers

Porous potting containers such as cement, whether used outdoors or indoors, wick moisture away from the soil and plant roots. Unfortunately, soil in these containers dries out quickly. Adding peat moss to the soil mixture helps it retain moisture and prevents hardening. To keep the soil loose and friable, add coarse sand and peat moss to container soil.
