Make sure your vases are perfectly clean. The stains in vases are usually bacteria that will get to work blocking the water uptake to the flower stems.
Stains that are difficult to remove with normal cleaning may be removed by filling the vase with water and adding a few drops of household bleach. Allow the vase to soak for a couple of hours then rinse well. Very well!
Clean Water and Preservatives
Clean water is essential for cut flowers. You can change the water in the vase daily or use a floral preservative. Check the vase often to see if it needs filling. Some flowers with woody stems drink a lot of water, especially in the first two or three days after being in their new 'house'.
Preparing the Flowers
Cut off a couple of inches of stem with sharp shears and be sure to remove any leaves that would be below the water level in the vase. Any left to drown on the stem will rot quickly and pollute the water.
