There’s nothing better in the entire world than receiving flowers. Someone thinks you're special and wants to express their appreciation for you, but it always seems like your flowers die within a week after getting them. Here are some ways to keep your beloved flowers alive longer.Cut Foliage and StemsThe minute you get your flowers, take all of the foliage off the stems. When you fill the vase with water, you don't want any foliage to go beneath the water. You also want to cut the very bottoms of your stems to open them up for fresh water to be able to enter.Right With SpriteFlowers need an acidifier to survive. An acidifier is anything that will make your water citrusy or acidic. If you add fruit juice to your water, however, it will change colors. A better option is to use Sprite because not only is it an acidifier, is also has sugar, which is also necessary for your flowers to stay alive. Try adding water and Sprite at a 1:1 ratio for best results.No Direct SunlightMake sure your flowers aren’t placed in direct sunlight. The sun is very harsh on flowers and will dry them out quickly. Just as humans will sunburn when they’re in the sun too long, flowers will also suffer in continuous sunlight.Replace WaterYou want to make sure to replace your flower vase water every two days. Bacteria likes to hide in the water and without constant water changes, will kill your flowers. Don't forget to add your can of Sprite back into the water as well.Re-cut the FlowersEach time you change the water, your should also re-cut the flowers. Every time you do this, you are enabling more water to get into the flower and flow up the stem better.
