Use 1” fresh water in vase, avoid water treated by a softener system. Cut stems to desired length. Add a drop of bleach to water (no flower food packages). After 2/3 days repeat the process again.

Follow these tips to keep your Hydrangea looking good in your vase:

1. fill a clean vase with fresh water and cut flower food
2. remove any excess foliage from the stem
3. cut off 1 cm from the stem and place in vase, repeat steps 1-3 every two to three days
4. do not place near a heater or direct sunlight, do not use metal vases
5. extra tip, should you have classic hydrangeas they can be displayed dried.  If there is no more water absorption and the leaves are limp, remove the leaves and drain the water and continue to enjoy them.
