Peach trees can easily be grown from pits, but be forewarned: Not all varieties germinate, like Red Haven, and those that do will take at least three years to begin producing fruit. Peach trees can be grown by placing the pit directly in the ground, but for a better chance at successful germination, proper pit preparation is suggested.
Thoroughly wash and dry your peach pits, being careful to remove every last fragment of fruit.
Put the pits in a plastic bag, which you will leave open, and keep in the refrigerator until December or January. This "cold treatment" will induce the pits to germinate.
Come December or January, remove the pits and soak them a few hours in tap water. Then place them in another plastic bag, this one filled with slightly moistened perlite, and put them back into the refrigerator. Check for germination after about a month and a half.
Once the pits have germinated, plant them in pots filled with potting soil. Transplant them outside once the last frost has passed, sprouting side up, root side down. Or, if you live in a temperate, frost-free zone, you can skip the pot stage and plant them directly into the ground. The pits should be buried at a depth of 3 inches.
