Over the years, I have successfully grown numerous peach trees from stones by simply planting them in pots after eating/processing the fruit as Bryant recommends.
Every year, I plant a selection of peach, plum, apricot and nectarine stones, the former usually fruit within 3 years.
The seedlings are repotted and allowed to grow on for a year ot two before planted in the community garden or given away.
Despite an electric fence around the gardens, possums have managed to get into the gardens and they have gnawed on the trunks and branches of many of the fruit trees so it is prudent to have back up trees to plant.
