Germination can take up to 3 months or more, so be patient. Then the actual stems and leaves will not appear until spring. It will likely take at least three to four years before you can start harvesting peaches from your new tree. Don’t be surprised if the fruit is different than the original, too. A tree grown from seed will probably produce different fruit from the original. To get a closer product to the peach you ate, bud graft your desired peach variety to the seed-grown tree.
