The present invention relates to a system for controlling plant and flower moisture transpiration and thereby extending the period of time in which cut flowers can be displayed before senescence produces a flower which has exceeded its aesthetic value. The systems of the present invention comprise: a) a first component in the form of a solution, said solution applied to the surface of a plant or flower exposed to air, said first component comprising: i) from about 0.1 % to about 20 % by weight, of a polymer of copolymer comprising monomers having the formula (I) wherein each R<1> is independently hydrogen, C1-C12 alkyl, C1-C12 alkoxy, phenyl, substituted phenyl, benzyl, substituted benzyl, carbocyclic, heterocyclic, and mixtures thereof; R<2> is hydrogen, halogen, C1-C12 alkyl, C1-C12 alkoxy, phenyl, substituted phenyl, benzyl, substituted benzyl, carbocyclic, heterocyclic, and mixtures thereof; X is hydrogen, hydroxyl, halogen, -(CH2)mCH2OH, -(CH2)mCOR, -(CH2)mCH2OCOR', wherein R is -OR', -N(R')2, -(CH2)nN(R")2, and mixtures thereof; each R' is independently hydrogen, C1-C8 alkyl, C2-C8 hydroxyalkyl, -(CH2)nN(R")2, and mixtures thereof; wherein R" is independently hydrogen, C1-C4 alkyl, and mixtures thereof; the index m is from 0 to 6, the index n is from 2 to 6; ii) from about 0.01 % to about 5 % by weight, of a surfactant; iii) the balance carriers and other adjunct ingredients; and b) a second component comprising: i) from about 0.1 % by weight, of a source of energy; ii) from about 5 ppm by weight, of one or more antimicrobials; and iii) the balance carriers and adjunct ingredients; wherein said second component is dissolved in water to form a solution and into which solution is placed the plant or flower to be preserved.
