If you want to put a peony in a vase, it is important to cut off the stems at an angle. Next, you should remove the lowest leaf and put it in a vase with lukewarm water. Want to help your peony last longer? You can add a spoonful of sugar, a dash of bleach or sparkling water to your vase. That will keep the water fresh so your flowers won’t wither too early.
You can also remove the sugar coat of the flower buds.
