A liquid composition is applied to a plant to provide a barrier to water vapor transmission. The composition dries to form a film on the surface of the plant. The film inhibits water loss and thereby increases the survival likelihood and quality of the plant. A particularly suitable coating composition comprises: from about forty to about ninety-five weight percent of a vinyl chloride or vinylidene chloride polymer; from about 1.0 to about 2.0 weight percent of a coalescing agent such as 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate; about 0.5 to about 1.0 weight percent of a surfactant such as a polyoxypropylene-polyoxyethylene copolymer; about 0.5 to about 1.0 weight percent of a viscosity increasing agent such as a urethane copolymer; and from about 0.3 to about 1.0 weight percent of a defoaming agent, such as silica.
