For flowers that are NOT in one of our eco vases please re cut stems before putting into water. A few drops of bleach can be added to the water keep away bacteria and prolong the vitality of the arrangement.
Roses love a deep vase of water, change every three days.
Remove pollen from lily's as this can stain fabric if it falls on it, you can just brush or blow it off.
Try and keep flowers in a cool room.
