flowered preservatives , available from flower store , contain sugars , acids and bacteriacide that can extend cut efflorescence life . These come in lowly parcel and are generally available where cut flowers are sold . If used properly , these can extend the vase liveliness of some thinned flower 2 to 3 time when compared with just plain water in the vase .
