Tips
Depending on the variety and how they are cared for at home, organically grown cut flowers can last between five and 14 days. However, if they are placed on a warm windowsill in direct sunlight, they won't last long.
If the water is never changed, allowing bacteria to develop in the flower water, this also contributes to a shortened shelf life. Therefore, how you treat your flowers after purchase or picking them plays a very important role in how long you can enjoy their beauty.
Clean the vase!
Mix a teaspoon of baking soda with white vinegar and scrub the inside of the vase to remove old bacteria. Rinse thoroughly before placing flowers in the vase. I recommend changing the water in the vase every day, recutting the flowers with a diagonal cut every now and then, and keeping the bouquet cool overnight, if possible.
The flowers definitely love being sprayed with cold water every day during the summer heat, as they can become dehydrated just like us humans.
It's also important that leaves never come into contact with the water in the vase. They will rot and then give off an unpleasant odor.
The flowers should also be kept away from ripe fruit, especially kiwi, mango, banana, and apple. The reason: Fruit releases the ripening gas ethylene, which causes other fruit in the immediate vicinity to ripen faster. Ethylene also accelerates the ripening process of the flowers, thus impairing their shelf life.
