Roses are often a part of special occasions--weddings, birthdays or other celebrations--and you may want to dry your rose petals and save them to use as potpourri or as a keepsake. Drying rose petals is a simple process, but it does take a few weeks and a fair amount of space.
Locate a dark, dry place, like a garage or work shed, to dry rose petals. It is best to lay the screens on a work table or shelf off the ground. As a guide, if you will be drying petals from a dozen roses, you'll need two to three 2 x 3-foot screens on which to lay the petals.
Lay down a piece of screen, such as a window screen, or a series of footed kitchen cooling racks. If using screens, raise them on pieces of wood or bricks to allow air to circulate underneath.
Remove the rose petals from each bloom one at a time, by hand. This is a time consuming and delicate process, as the petals can tear. Grasp each petal at the base for best results.
Place petals onto drying racks in a single layer. Keep the petals from touching each other, as they will stick together when dried.
Leave the rose petals to dry for about a week, then check on them. If they are not completely dried--they will crumble easily if totally dried out--then leave them for another week.
Remove petals from the drying rack and store them in an air-tight container if you will not be using them right away. For immediate use as potpourri, put the rose petals in an open container. You may also want to crush them and put them into a sachet.
