How to dry flowers: With the microwave
Dry flowers in minutes instead of weeks by using a microwave. Choose the flowers for drying. One at a time, place the flower in a microwavable bowl and cover with about four cups of cat litter. Microwave on high for two to three minutes. When the cat litter is cooled, remove the flower and brush off excess.
How to dry flowers: With silica gel
If you want your flowers to look just like they did in your garden, trying using silica gel. The sandy-like substance can be found at craft stores and works best with sturdy flowers like zinnias or roses. Bury your blooms in a large container of silica gel. In a few days to a week, gently uncover vibrant, preserved flowers.
