Is there a trick to grow a peach tree from a pit?

The trick is cold. Peach seeds won't sprout until they've had a winter, so fake one: crack the pit open carefully (a nutcracker or vice), take out the almond-looking seed, wrap it in a damp paper towel in a bag and keep it in the fridge for about two to three months. Check now and then, once a root pokes out, pot it up. Just know the fruit might not match the peach you ate. Seedlings often come out a bit different, and it'll be a few years before you see any.
