Water 

Water should be changed daily to maximize flower's life. Room temperature water is required. To keep bacteria at bay, clean out the vase every 2-3 days. If it is a flower foam arrangement, add water every 1-2 days to keep flowers at optimal hydration. Always remember to pick out fallen foliage or petals that have fallen into the vase, as those can contaminate the water.

    Trimming Flowers 

 For arrangements in vases, remove 3/4" to one inch from the bottom of the stem every few days and be sure to cut the stem at an angle to allow the flower the best chance to take up water. Use a sharp knife or sharp scissors. Avoid smashing the stems because that can damage the water vessels. 

Temperature

Arrangements should be placed in cool spots inside the house (between 65 to 72 degrees Fahrenheit). Should be away from direct sunlight or heat, which would cause flowers to wilt faster.
