Try this a-peel-ing trick

You can use the rinds of oranges, lemons, limes, grapefruits, and other citrus fruits to plant seeds. The scent of citrus fruit and peels helps ward off pests and animals. They also offer nutrients such as nitrogen, phosphorous, and potassium. And finally, citrus peels are relatively acidic, which offers the best environment for specific seedlings such as radishes and peppers to grow. To plant a seed into the rind, fill a half citrus rind with soil and then place the seed in the center. Then, place it on a windowsill until it sprouts. Once it sprouts, transplant the sprout (citrus rind and all) directly into a pot or your outdoor garden to continue growing. (The rind will eventually break down and your seed will continue to grow.)
