Can I make my own flower food?
Flowers will last much longer if they are placed in water that contains nutrients and antibacterials. Adding some lemon juice, sugar and bleach will extend the life of your flowers.
Try adding two tablespoons of lemon juice, one tablespoon of sugar, and a half teaspoon of bleach to one quart of water. You can also use apple cider vineager in place of the lemon juice, or replace the sugar and lemon juice with lemon-lime soda.
