Growing any tree from its fruit seed is not a difficult task. Keep in mind that the tree that germinates from an apple seed may not produce the same fruit as the tree, as the fruit may have been cross-pollinated from another variety of apple tree. This will cause a different offspring from the fruit's seed. The tree that is grown will always be a full-sized apple tree, even if the fruit came from a dwarf variety. Dwarf fruit trees are grafted to special rootstock that keeps the small size in the upper branches. Preparing apple seeds for planting is a simple process.
Select apples that have a good outer flesh with no physical damage. Wounds in the outer skin may harbor unwanted bacteria that can be transferred to the seeds.
Cut the apple in half with a knife. Scoop out the seeds and surrounding pulp with a spoon.
Place the pulp and seeds into a sealed glass jar with approximately ¾ inch of water. Close the jar. Shake the seeds, pulp and water to mix. Allow the pulp and seeds to set on a counter top, out of full sunlight, for two days.
Rinse the seeds with clean water to remove any pulp. Place 1 inch of water in the jar. Remove any seeds that float. The seeds that sink are the most viable for germinating.
Place the sinker seeds on paper towels to dry overnight.
Store the seeds in a plastic bag in the refrigerator for three months to stratify the seeds. Some varieties may require up to four months of refrigeration to germinate in warm soil.
