Cherry tree seedlings can easily be grown from ripe and germinated cherry pits or seeds. While a cherry tree sapling will grow, it will likely not be an exact replica of the tree from which the seed was taken. Cherry seeds can be sown outdoors in the fall and will germinate in roughly three months. Plant two to three times the number of seeds than you want young trees to allow for a failure rate and thin the saplings later if needed.
Harvest your cherry seeds from the ripe fruits in the summer. Eat or clean off the fruit flesh and rinse the seeds of the sweet residue. Store them in a lightly covered cup or open plastic bag until early fall.
Till up an area with nutrient rich planting soil to a depth of a foot and a diameter of at least a foot for each seed. Use a hand trowel to turn, loosen and lighten the soil. Amend weak soil with several pounds of compost and aged manure if the soil is lacking in organic matter mixing it in well with the ground soil.
Nestle the cherry seeds down 1/2 inch into the prepared soil and cover over with soil pressing down lightly to make contact with the seed. Water the seed into place, making the surrounding soil wet but being careful not to wash the soil away or expose the seed.
Allow 90 to 105 days of temperatures of 41 degrees Fahrenheit or below for the seed to germinate. When a green shoot emerges in the spring, keep the soil lightly moist and refrain from fertilizing the seedling with anything other than compost or manure for its first year. Thin extra or weak cherry saplings at two years of age if need be.
