Sprouting peach trees from seed is a straightforward process. But sprouting grocery store peach seed is rarely ever a good idea. Instead, look for fruit grown locally. Neighbor's yards and local farms are a great place to go and ask for peaches. Since these plants are already growing in your area, you have the best chance of raising them successfully in your own yard.
Slice the peach to remove the seed or eat the fruit.
Scrub any clinging fruit away from the peach seed with a nylon-bristle brush and running water.
Leave the peach pit outside to dry for 24 hours. If the pit attracts flies, scrub and dry it again.
File down the ridges on the pit in three or four places on the seed with a nail file or piece of sand paper. Stop when you expose the brown seed in the center. Do not file through the brown seed.
Place the peach seed in a freezer bag.
Seal the lip of the freezer bag, but leave roughly 1 inch open to allow the seed to breath. Place the freezer bag in your refrigerator's vegetable crisper drawer. Keep the bag in the refrigerator until late December/early January. Do not store apples or bananas in the refrigerator during this time. Check on the freezer bag's moisture level periodically. There should be a light layer of condensation on the walls of the bag. If that begins to dry out, spray the peach seed with a little water.
Take the seed out of the bag and soak it in room-temperature water for three to four hours.
Fill the plastic freezer bag half full with moistened vermiculite.
Plant the peach seed in the center of the moistened vermiculite.
Seal the lip of the freezer bag, leaving 1 inch open to allow the seed to breath. Return the freezer bag to your refrigerator's vegetable crisper drawer. Check on the freezer bag's moisture level periodically, and check the bag daily for signs of sprouting after roughly 45 days. Spray the vermiculite with a little water if it begins to dry out. When the peach seed's root is 1/2 inch long, transfer it to a pot.
Fill a small pot with moistened seed-starting soil.
Plant the sprouted peach seed 2 inches deep.
Place the pot in a spot where it will receive full sunlight. Water whenever the top inch or so of the soil dries out.
Plant the seedling outdoors once all threat of frost has passed in spring.
