1) Remove bottom leaves if present, trim stems and place into fresh water;
if you have flower food, toss it in! 

   2) Change water every 2 days for longevity and outward appearance.
   Stem blocking bacteria builds up very quickly in the display bucket/vases
and a pungent odor will present itself if the water is not changed regularly. 

   3) Customers receiving flowers in stage 3-4 under normal domestic
conditions should expect vase life of 6-8 days.
