Bing cherry trees, a hybridized variety of sweet and sour cherry, can be propagated by seed and will result in a healthy cherry tree, though it is not likely to produce fruit identical to that of the parent tree. Bing cherry seeds must be mature when harvested, cold-treated and kept moist for effective germination to occur. To start a Bing cherry tree, prepare and plant several more seeds than are desired in future trees to account for possible germination or seedling failure.
Harvest fresh Bing pits when the fruit is mature, near the end of harvest. Peel the fruit flesh away from the pit and wash the pit in tepid running water, removing as much of the flesh as possible.
Plant individual seeds in the fall directly in the ground soil or in seed trays or pots filled with light, sterile potting mix. Bury the clean seed, one per hole or pot at a depth of 1/2 inch. Cover over the seed with soil and water until drenched, but not sopping wet. Ensure that the pit remains covered by the soil.
Allow 90 days of temperatures between 33 and 41 degrees F to pass before germination occurs. Maintain evenly moist soil around the pits and never allow the soil to become dessicated.
Transplant container-started seedlings into the ground soil in the late spring of the first year or in the late spring of the second year, if you choose to grow them in a pot the first year.
Thin or relocate ground-started seedlings in the second to fourth years to prevent disruption of the maturing root mass.
