Sand

Sand is one of the agents most frequently employed by the gardener in the culture of potted plants. The kind most suitable to his purpose, is either silver sand, or drift river-sand, both of which are silica nearly in a state of purity. These sands being very slow conductors of heat, and affording a ready escape for superfluous moisture, are admirably adapted for promoting the rooting of cuttings, and preventing the damping-off of seedlings. See Potting, Soil, and Damping-off.
