Stratify the seeds for 3 to 4 months. Wrap them in moist peat moss or vermiculite and put everything in a plastic baggie. Put the baggie in the refrigerator and wait.
Transfer the seeds to flats and add more peat moss or vermiculite. Cover and leave in a warm and dimly lit area. Poke holes in the cover so air can circulate.
Allow the seeds to germinate. This can take a long time depending on the plant and its location. Be patient and watch for any signs of growth.
Move the seeds to a well-lit area once they germinate. Keep your new fruit trees indoors and away from the harsh conditions until they are hardy enough to handle it.
Transplant the fruit trees when they're ready. You may have to repeat this step many times depending on how large your fruit tree grows.
