Seed may be sown outdoors in the fall or stratified seed may be planted in the spring. If you have appropriate lights, a cool room for growing on the seedlings, and patience to correctly harden off the seedling before taking it outdoors, you could stratify now, sow in winter indoors - your choice. Stratify the seeds at approx 33 to 41 F in damp sterile medium, 95 to 105 days. Seeds should be planted about 2 inches deep.. ( peaches will not reproduce true from seed, the tree you grow may bear fruit that does not resemble the peach you ate)

Do peaches grow where you are? Keep in mind, it will take years, maybe 8-10 years, before you get any fruit, and it may not be anything you'd want to eat, since they are hybrids.

Of the common fruits, peaches are a good choice to grow from seed. Peaches fruit in 3 or 4 years, and since they are self fertile, you have a pretty good chance of getting decent fruit from a seedling (unlike apples for example). Several people on the fruit forum have grown peach trees from seed. I had a volunteer that fruited in it's third season at 9 feet tall. The fruit was pretty good, but I cut the tree down because it was a pest magnet....borers in the trunk, Japanese beetles eating the leaves, and moth larvae in the fruit.

I would plant the seeds now where you want the tree to grow. Protect the area with a screen cylinder/cage so no animals dig up the seed or eat the seedling when it emerges in the spring.
