When you get home with your flowers and the little sachet of flower preservative is missing - urgh...
I found this simple recipe to keep your blooms lasting longer?
Homemade Flower Preservative
1 teaspoon of sugar
1 teaspoon of household bleach
2 teaspoons of lemon juice
Dissolve all the ingredients in one quart of warm water. If your arrangement needs more water then double the ingredient quantities and the the amount of water.
How does this work? Each ingredient has a specific job to keep the flowers lasting longer. Sugar provides the nutrition the flowers would normally get from the soil via the roots, bleach ensures the water remains clean and the lemon juice keeps the solution acidic which helps with the uptake of water.
Don't forget to change the water every few days and mist occasionally.
