Bouquet of flowers

Place fresh water in a vase, pour in the flower food, trim the flower stems and place into water as soon as possible to ensure your flowers stay fresh.
Repeat this process every 2 days
When flowers stems expire, remove them from the vase, this will help the remaining flowers stay fresher for longer

Arrangement (in floral foam)

Pour water into the foam each day to keep the foam wet to allow the flowers to have a water source.
When flowers stems expire, remove them from the arrangement, this will help the remaining flowers stay fresher for longer
