Yes, you can start a cherry tree from a pit. However, keep in mind that cherry trees grown from pits may not produce the same quality or variety of cherries as the parent tree. To start a cherry tree from a pit, remove the pit from a ripe cherry, wash off any flesh, and let it dry for a few days. Then, plant the pit in a pot or directly in the ground during the fall. The pit will require a period of cold stratification before it germinates in spring.
