Trees can be grown from seed to adulthood in most cases without any problems. However, if you have a tree that has been genetically altered over time and doesn't produce fruit or seeds, then it must be propagated using the cutting method. This method will grow a new tree from the branch cutting of another tree. The cutting method can also be done with trees that do produce seeds, and is used to grow fruit trees that will start to produce fruit quicker than those grown from seed.
Cut off a small section of a branch tip about 6 to 8 inches long. Make sure that it is fairly new growth; not completely green, but not hard wood either. Clip it off at a notch where another twig is branching off. Cut at an angle.
Prepare a small pot with a mix of peat and perlite.
Dip the cut end of the cutting in rooting hormone and shake off the excess.
Create a small hole with your pinkie and slide the cut end into the potting mix. Make sure it goes down 2 to 3 inches. Press down around the cutting with your fingers to secure the cutting in the growing material.
Water the soil to dampen it. Do not soak it down. Check on it daily to make sure the soil stays damp.
Place the pot in a well-lit area. After several weeks, tug gently on the cutting to see if it resists. If it does, then roots are starting to form. Wait a few more weeks before moving it to a bigger pot.
