how do I grow a cherry tree from seed
The problem is the germination - it can take months. Take about 10 seeds and clean them thoroughly, of all pulp. Then they need to be stratified. That means putting them in the fridge in a vermiculite mixture for about 2 or 3 months. After you take them out, they may germinate. or they may have germinated already. Then you can plant them in sterile soil and give them sun each day, keeping the soil fairly moist.
plant it, water it, keep it in the sun pretty straight forward
