Heaths, Greenhouse.--For their successful growth Heaths require a
well-drained soil, composed of three parts finely pulverised peat and
one part silver sand, free ventilation, and a careful supply of water,
so that the soil is always damp. If they suffer a check they are
hard to bring round, especially the hard-wooded kinds. Some of the
soft-wooded Heaths, such as the H. Hyemalis, are easier of management.
After they have flowered they may be cut hard back, re-potted, and
supplied with liquid manure. The stout shoots thus obtained will bloom
the following season. (_See also_ "Ericas.")
