Flowers can be preserved in different ways using a variety of chemicals and other products. It all depends upon which flowers you are choosing to preserve and what chemicals and accessories you have both, access to and preference for use. Now that you have all the required products to preserve your flowers, you are good to go. This would allow you to save your flowers and give them a longer life. You may want to preserve flowers using sugar and bleach.
What you will need for that is, of course, a vase with some water, the flower, a little bleach and sugar. Before you put flowers in water, you have to make sure that you take all the leaves out. Usually leaves in water make the water go bad very fast. What you are going to do next is take a tablespoon of sugar and put it in the water. Then you are going to take a tablespoon of bleach and put it in the water too.
Bleach will help the water stay clear. Of course, not forever, but for a long time. And the sugar will give the flower a kind of food that the flower can have during their stay in the water. So, this combination helps the flower stay longer and look nicer for at least a week. In a very hot weather or air condition, it will help it stay for at least a week in good shape.
