In the Autumn sixteen inch cuttings are taken from the parent plant. Basal
ends of the cuttings are Immersed in 100 ppm IBA as IBA Water Soluble Salts
dissolved in water for 6-12 hours.
Cuttings are then bundled in groups of 25. Bundles are wrapped in perforated
transparent plastic sheeting.
The wrapped packages are placed into crates which are piled to allow air
circulation.
The crates are left in cold storage at a temperature above freezing (33-35F)
for the Winter.
Ethylene generation is checked regularly as it could be toxic to the
cuttings.
During cold storage a callus ferrule forms around the lower end of the basal
end.
In the Spring the cuttings are planted in the open.

Hello all,

I have used the above basic method to propagate P. cerasifera with slight modification and it works very well. I take 12 inch cuttings pencil size about Nov. 1 (zone 5B), remove leaves, quick dip bottom 1/2 inch in Woods Rooting Liquid, air dry until the liquid is dry (a few minutes). Now I bundle (hand full size) these cuttings and place in 1 inch damp milled sphagnum in a vertical position at about 60 degrees for two weeks. During this time the basel end callouses. I then reopen the bundle insert a little more sphagnum along the length of the bundle to retain moisture, but not wet, wrap entirely in heavy plastic and store vertically positioned in the cooler at about 35 degrees. I also store apples in this walk in cooler and haven't detected any degradation of material. In early spring as soon as ground temp reaches about 60 degrees they are placed in the growing beds, 6 inches deep and 6 inches above ground level. At this time some of the cuttings will have already begun to root.    

Will this work with cherries, don't know, haven't tried it.
