An apple seed is an intriguing little object of much wonder. It doesn't seem like it could produce a whole apple tree judging by its small size and being just a little nut-like center covered in a thin smooth wood veneer. Yet, plant it and you will find just how amazing a tree the apple seed can produce.
Moisten the paper towel with a teaspoon or two of water. It should be damp but not wet. Place the apple seeds off center and then fold the napkin in half three times and slide into the plastic bag.
Place the bag in the vegetable compartment of your refrigerator where it can sit undisturbed for about 6 weeks. This is to mimic the time of dormancy the seed would normally go through outside during the winter and is called stratisfying.
Check the seeds after the 6 weeks have passed to see if they have started sprouting. If there is no sign of growth, place them back in the towel, in the plastic bag, and into the refrigerator for another week. You should see about a third of them sprout at this point or soon after.
Pour the potting soil into the plant pot and make a 1 inch hole with your finger. Very carefully, drop the sprouted seedling into the hole and push enough dirt over it to fill in the hole. Tap the soil gently and water with warm water.
Place the planted sprouted seed in a sunny window where it can grow until the weather warms outside. Rotate it every week so it can grow straight and transplant it outside when all danger of frost has passed.
