You can cut flowers in your garden to make a beautiful centerpiece for your kitchen table, but you'll discover that cut flowers do not stay fresh for long. Within a few days you will notice the flowers beginning to wilt and die. Luckily, there are a few ways you can keep your cut flowers fresh for a little while longer.
Set your cut flowers in the refrigerator for six hours. While the flowers are in the refrigerator, move on to step 2.
Place 6 inches of cold water in a vase.
Add your bactericides if you purchased the cut flowers from a flower shop. Bactericides come in a little packet from most flower shops now. They keep your flowers from wilting due to bacteria or fungi. You can buy them for your home use as well.
Drop one penny and one aspirin in your water if you did not purchase your cut flowers from a flower shop. The penny will kill any fungi in the water, and the aspirin will make the water slightly more acidic. This will keep your fresh cut flowers alive longer.
Set your flowers in the vase and remove any leaves that are below the water line.
