Answer: While you can air-layer almost any plant, fruit trees are usually grafted onto vigorous rootstocks rather than grown on their own roots. If you'd still like to try, you can take a small branch that is an inch or less in diameter, make a small notch (this is where roots will develop), hold the wound open with a small pebble, wrap the site with moistened spaghnum moss and tape plastic over the entire thing. Within a year, depending upon how vigorous the plant is, new roots should form at the site of the injury. Once that happens you can cut the branch off the parent tree, and transplant it to a container of potting soil, or directly into the ground.
