Carefully unwrap the bouquet and discard paper, cut open the plastic water pouch over a sink to avoid a spill and discard the plastic wrap. Remove any water tubes. Snip the stems with sharp shears and place into a clean vase with cold water with a dash of floral preservative. Place the flowers in a cool spot out of the sun and lightly mist with water daily. Recut stems every two days and place back into fresh clean water. Snip off any withering blooms throughout the week.
