To prolong the life of your flowers: - Use a clean vase and change the water often, ideally, once daily. - Use room temperature, clean water in your vase. - Add flower food to the water, which helps give the flowers a source of nutrition, encourages hydration by lowering the pH of the water, and inhibits bacterial and fungal growth. - Keep your flowers in a cool location, out of the sun, and away from ripe fruit and breezes. - Re-cut the stems often. A slanted cut increases hydration and prevents the end of the stem from resting directly on the bottom of the vase. - Remove leaves below the water line to prevent rot.
