To preserve your artistic flower arrangement be sure to keep your vase three fourth full of water. Do not put cold water when you replace the water, always use warm water. And when your water vase begins to become cloudy or you can smell a foul odor, you have an option to replace the water or put a little bleach. Make sure to clean your flower vase evenly between uses, you can also soak it in water with a little bleach to disinfect it. You can always do this before you use your flower vase.
Place your ornamental cut flowers into your water vase, make sure that you put it one by one. If it's going to be a design or floral arrangement against a wall or flat surface you have to put the tallest or longest cut flowers at the back. If your design or flower arrangement will be visible from the sides place your longest or tallest flowers in the middle. Begin with the longest or the tallest, and then go out to the lips or edge of your flower container. Now, take time to look at your flower vase, is it beautiful and pleasing to see? Did it turn out to be symmetrical? Is there a spot or an area that needed to be filled in with more flowers?
