Hang it upside down The final step to the process in keeping your flowers forever is to hang them upside down to dry. We suggest taping them to a wall in a cool, dark space to preserve the color. If you prefer a slightly darker dried rose color, hang them at a window exposed to the sun as it helps dry the rose faster.
Do dried roses last forever?
The Typical Lifetime of Your Dried Flower Bouquet Dried flowers last an average of one year. The color of your dried flower arrangements will naturally fade over time, so if you buy dried flowers that have also been dyed, they will last even longer.
How does hairspray make roses last longer?
Here's how to do it: Trim your flower stems as usual.

Hang the flowers upside down (in a well-ventilated space) until the hairspray dries completely.May 3, 2019
