The main reason for microwaving flowers is to dry them in a hurry without using high heat, according to Better Homes and Gardens. Using high heat on flowers may cause them to turn brown.
Dried flowers, whether through microwaving or another method, are suitable for creating distinctive indoor decorations. Dried flower arrangements last a long time. They are also low maintenance. When gardeners dry flowers themselves, they extend the value of their gardening activities.
Pressing flowers in a microwave involves first placing them between two sheets of absorbent paper pressed between tiles. The tiles must be secured with rubber bands. Gardeners heat the pressed flower in 30- to 60-second intervals, allowing the flower to cool down in between sessions. After being dried in the microwave, flowers get placed in a book or under a heavy object for a day to finish the pressing process.
Another method of drying flowers in the microwave involves placing silica gel in a microwave-safe container, placing the flowers inside and covering with more silica gel. In this case, the microwave should be set on the defrost setting. The flowers get microwaved for two to five minutes before being allowed to finish air drying in the container.
According to Pro Flowers, Gerbera daisies, chrysanthemums, roses and tulips work well with the microwave drying technique. The process preserves their structure and color. Air drying is preferable for bouquets and flowers such as roses and lavender.
