Make sure the vase or container you will be using has been thoroughly cleaned, dirt and bacteria in the water will affect the life of the flowers and make the water murky. Fill the vase with plenty of clean water.
TIP: Add a pinch of sugar, a drop of bleach and a squeeze of lemon juice into the water. The sugar will act as a food source for the flowers, the bleach will help to kill off bacteria, and the lemon juice will lower the pH.
