Cut all the stems of the bouquet at an angle before placing them in a vase. This will increase the area of the plants to absorb water. Also, remove all leaves and thorns that come into contact with water to prevent rotting.

Make absolutely sure that the vase you use is well cleaned, and fill it with lukewarm water. Also note that some types of flowers, such as tulips, hyacinths, calla or daffodils, do better when they are only a few inches in the water.

Change the water every two days and clean the vase to remove bacteria and fungus. If using a freshener, simply add any missing water, as flower care products contain active ingredients that inhibit bacteria and rot.

Also re-cut flower stems every other day to ensure that plants receive adequate water.

Never expose bouquets to too much sun or heat! Drafts also shorten the life of cut flowers. Also, avoid proximity to fresh fruit or televisions.
