The large pit contained in the center of each peach fruit is a protective covering for an internal peach seed. You can plant the peach seed and care for it until it grows into a new peach tree. Although the resulting tree will not be identical to the parent tree, it will be similar. However, before you can plant the peach seed you must extract it from the pit and prepare it.
Remove the pit from the peach fruit, if not already done, by cutting off as much of the fruit as possible using a knife. Rinse it under running water until the pit no longer feels slippery.
Lay the pit in a dry location with good air circulation and allow it to dry for at least three to four days. The pits must be completely dry so that you can crack them open.
Place the peach pit in between a pair of pliers -- or in a vice grip -- and press down on the handles with firm force until you feel the peach pit crack. Pull away the cracked pit to reveal the inner peach seed, which is white and looks like an almond.
Place the seed into a plastic storage bag and seal the top of the bag halfway. Insert the bag into a refrigerator and leave it there until you are ready to begin the germination process. You can also store the seeds in a room temperature location that is out of direct sunlight.
Remove the bag from the refrigerator and fill it with 1 inch of water. Close the bag up tightly and allow the seed to soak in the water for two to three hours.
Open the bag and add an all-purpose potting soil to the water until the soil is damp but not soggy. If the mixture is still too wet, add more soil. Seal the bag up tightly.
Place the bag back into a refrigerator that has a temperature of between 34 and 42 degrees Fahrenheit. Leave it there for five or six weeks and then check it daily for a small seedling. When a seedling is seen, remove the bag from the refrigerator and plant the peach seedling as desired in a pot or outdoors.
