A nectarine is a variety of peach with smooth skin. With careful attention to detail, a new nectarine plant can be sprouted from the seed. It is easy to sprout a nectarine seed, and in three to five years, you should have a fruit-bearing nectarine tree.
Choose a pit from a tasty nectarine. Try and get a pit from a nectarine that was grown near your home. In the middle-to-late weeks of summer, visit farmer's markets and purchase home-grown nectarines. When you find a variety that you really like, save the pit.
Place the pit on a paper towel and allow it to dry out for several days. This will make it easier to crack open the pit and extract the seed.
Crack open the dried-out pit. Carefully tap it with a hammer, or slowly squeeze the pit in a vise until it cracks. Whichever method you choose, proceed with caution to avoid damaging the seeds within the pit.
Place the seeds in a sealed container in the refrigerator for temporary storage.
Remove the seed from the sealed container approximately four months prior to the last spring frost. Soak the seed overnight in room-temperature water. The next day, cover the seed in the jar with slightly-moist potting soil. Place the lid on the jar and place the jar in the refrigerator.
Check the jar every few weeks to see if the seed has sprouted. Keep the nectarine seedling in the refrigerator until it is approximately one month until the last spring frost. Plant the nectarine seedling outside if you live in zones 6 through 9. If you live in zone 4 or 5, plant the seedling in a very large pot.
