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.
You may start by placing your foliage that you will use in a water vase. You have to make sure that you keep it around the lips or edges. Stick with the plan to place them the lips or edges of your water vase with a layer of your Foliage. When it is too big or too thick, it ends up detracting from your cut flowers. And if it is small or too thin, visual contrast will not show.
