Your microwave oven can be used to dry flowers and leaves. Cuttings should be fresh flowers or perfectly shaped leaves, with all but 1 or 2 inches of the stem cut off. Don't dry flowers or leaves that have begun to wilt or fade. Processing time varies using this method, with flower types, humidity and type of microwave all a consideration. Prepare to do some experimenting with the processing time.
Cover the bottom of the casserole dish with an even layer of silica gel, between 1 and 2 inches deep.
Insert the flower stems into the silica gel.
Move some of the silica gel (not the portion holding the flowers) to cover the flowers. Do this gently. Completely cover the flowers with the silica gel.
Set the glass of water toward the back of the microwave.
Place the dish in the microwave and close the door.
Cook on high from 45 seconds to three minutes, depending on the flower. You will need to experiment. A carnation might take between two and three minutes, while a pansy might take 45 seconds.
Remove from the microwave oven and allow the silica gel to completely cool before removing the flowers, at least 12 hours.
