100 Pcs Apple Seeds Bonsai Apple Tree Seeds Some home growers buy young trees from nurseries and plant them outside, while other gardeners prefer to grow trees from seed. Growing trees from seed can offer both rewards and unique challenges. By planting according to a well-designed method, you can watch your apple trees grow from raw seeds to sprouts. Place the seeds inside moist media (peat moss, vermiculite, sand) in a container, and place the container in your refrigerator. This stratification, or cold treatment, of your seeds is essential to germination. As long as a consistent temperature of 35 to 40 degrees Fahrenheit is maintained inside the refrigerator, the seeds should be cold treated in three to four months. Place the cold-treated seeds inside a pot or other container filled with potting media. Make sure the potting media is loose and well drained. Cover the container in black plastic, and poke a few holes through the top of the plastic. Apple seeds and many other fruit trees need high relative humidity and good air circulation to germinate properly; covering the container in black plastic with holes provides both conditions. Depending on cultivar selection and on many other natural factors, germination and sprouting may take place in a few days to a few months.
