Lath is a thin, narrow strip of wood used to support plaster on interior walls and ceilings. A lath house is a structure made of wooden strips or laths placed 5 cm apart that is used to protect and nurture young plants. Lath houses provide protection from hot winds, sunlight, and low temperatures while maintaining humidity. They can be covered with plastic sheeting in winter for additional protection from cold and are useful for raising seedlings, cuttings, and young rhododendron plants before planting in gardens.
