Most garden peach trees are grown from grafted rootstock plants, usually purchased from tree nurseries. However, growing a tree from the hard pit inside a peach fruit is possible. It may take several years for a tree to reach fruiting age, and not all seeds will germinate. Peach trees are also not able to tolerate cold temperatures, so make sure you're located in USDA plant hardiness zones 5 to 9.
Dig a hole 4 inches deep in a location with around 10 to 18 feet of clear space around the hole. Choose ground that's fast-draining, preferably on a north-facing slope. If puddles remain on the ground for a day or two after raining, prepare a raised bed, according to Texas A&M University. Pile soil to a depth of 12 inches and a diameter of 8 feet. Ring the soil with wood or plastic.
Insert the peach pit into the hole in the fall, and cover with soil. Plant several pits to maximize the chance of successful germination. You can always move plants if several come up. Spread a 2-inch layer of pine needles or straw mulch over the area.
Water the mulched area, and continue to water frequently throughout winter. Pull out any weeds that sprout up near the pits.
Water any peach saplings that emerge in spring once a week, with deep soaks during warm summer periods.
Wrap foil or a growth tube around the trunks of established trees for added protection against sun scald and low temperatures. Add further straw mulch to the ground, but keep a clear gap between the trunk and the mulch to stop wood rotting.
Add fertilizer to the ground around young trees that are more than 10 inches tall, according to Texas A&M University. Use a cup of ammonium sulfate spread around the tree to a diameter of 2 feet. Prune back all but four to six strong branches in May on trees over a year old.
