If your flowers are drooping or wilting, don't worry! Sometimes air can get trapped in the tips of the stems, which makes it difficult for them to drink water. This means the stem loses its water tension and so begins to droop.
If this happens, we recommend that you take the flowers out of the vase and cut about an inch off of each stem at a 45 degree angle. Place the flowers back in cold, fresh water and you should being to see them perk back up within 24 hours!
