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.
To get a beautiful flower design or an arrangement, you don't need to show all of these three. The most important here is that your design has ornamental flowers; you will still get a terrific and an artistic flower arrangement.
