The black cherry tree, Prunus avium, is a hardy plant that thrives in full sun and does especially well in zones 5 through 8. Due to the ability of cherry blossom pollen to travel far distances, propagation of cherry seeds is unpredictable and an unwise venture for cultivators. Instead, modern cultivators use a technique called grafting to propagate their orchards. Grafting is the process of merging a fresh branch from a desired fruit variety with the root system of a seed-grown tree to produce a locally grown hardy fruit tree that will produce reliable fruit.
Slice the understock's branch off at 1 foot from ground level. Slice it diagonally and in one clean slice to avoid damaging the plant. The cut should be 1 1/2 inches long.
Slice the budwood in the same manner and position it onto the understock, trying to match up the green layers (cambial layers).
Bind the union tightly with grafting tape. Grafting tape is a special wax-based tape that will stretch and expand with the tree to prevent damaging the graft site.
Paint the union area with a layer of grafting compound to seal in moisture and prevent disease.
Put the tree in a warm, sunny place for eight weeks as the graft heals and grows.
Remove the tape when leaves form on the budwood. Then transplant it outdoors.
