What does it mean when the water in the vase becomes yellow or filmy?
If the water in your flower vase becomes discolored you have not correctly prepared your vase water with the flower food packets enclosed in your shipment. Flower food inhibits the growth of mold and bacteria in your vase water, and prevents the common bacteria growth you would encounter with regular tap water. However, if this has occurred, simply discard the filmy vase water, re-cut your flower stems, and prepare your vase anew according to the directions printed on the flower food packets enclosed with your FiftyFlowers.com roses.
