If you purchase cut flowers from a flower shop, you will see that they come with a little food packet that will help keep your cut flowers fresh longer. If you cut your own flowers, however, you will not have this packet. Your flowers will wilt quickly if you don't do something to preserve them. Luckily, there is an all natural way to preserve your cut flowers at home.
Fill a third of your vase with regular lemon-lime soda.
Fill the rest of your vase with lukewarm water.
Add quarter of a tsp. of bleach to the water, and give it a stir.
Choose the flowers from your flower garden that you want to use in your vase. Cut them at an angle with your gardening scissors.
Place the cut flowers in the vase as soon as you have cut them.
Place another quarter tsp. of bleach in your flower vase every four days to keep the flowers fresh.
