Prepare flowers and vase:
To prolong the life of your flowers, it is important that you prepare both the flowers and the vase well. Remove all leaves and foliage from the flowers that will be under the water level. The leaves rot inside and so does your flower. Cut the flower at angle using a sharp scissor. The angle encourages water intake. Clean the vase well with a disinfectant or simple hot water.
Aspirin is a known flower preservative apart from its medicinal properties. Before you fill your vase with water, place a crushed aspirin tablet at the bottom and the pour in the water.
Use a flower preservative:
There are many commercially available flower preservatives. However, you can also make one for yourself using simple ingredients from the kitchen.
One popular flower preservative is bleach. Add ¼ tablespoon of household bleach to every one quart of water in your vase. The bleach works as a great anti-bacterial option. Adding sugar with bleach does wonders and adds days to the calendar.
Another preservative may appear very odd. Seems like our flowers share the passion for soda. Pouring the last drops of your carbonated drink into the vase is going to extend the life of your flowers. Using a clear soda like sprite will help you keep the presentation if your vase is a transparent one.
Our knight in shining armour vinegar is another helpful solution from the kitchen cabinet. 2 tablespoons of vinegar and two of sugar is going to do a marvellous job.
