Potpourri has a warm, inviting fragrance that suits almost any room in your home. Unlike scented products that might contain chemicals -- such as candles and sprays -- you can make potpourri with only natural ingredients. Some of the most appealing ingredients for potpourri include citrus slices from fruits, like orange, lemon, lime or grapefruit. Before adding citrus to a batch of potpourri, first slice and dry the fruit.
Wash the citrus fruits thoroughly with clean, cool water.
Cut the fruits into thin slices about 1/4-inch thick or less. If you slice the fruits too thickly, they will take longer to dry.
Lay the citrus slices in a single layer on a baking rack.
Dry the slices at 175 to 200 degrees Fahrenheit for four to six hours. Check the fruit periodically to ensure it's not turning brown. Dried citrus fruits should retain their bright color.
Remove the fruit from the oven and allow it to cool before using it in potpourri.
