Propagation of prunus by basal long soak

We use IBA Water Soluble Salts (we get ours from from Hummert 800-325-3055)
*Immerse method* to hard to root plants like prunus. It is also used to root
prunus rootstocks, evergreen, deciduous shrubs, conifers, platanus
acerifolia (London plane)
For illustration see
Macdonald, B. 1986. Practical Plant Propagation for Nursery Growers (Volume
1). Timber Press, Portland, OR.
and
http://www.rooting-hormones.com/IBAmethd.htm

Immerse the basal ends of the cuttings approximately one inch in the IBA
Water Soluble Salts solution for 4-12 hours.
For cuttings propagated under mist the treatment is a maximum of four hours.
The cuttings are planted immediately after treatment.
For woody and herbaceous cuttings use 50-150 ppm IBA as IBA Water Soluble
Salts dissolved in water.

European growers have for over fifty years used this Immerse method to root
cuttings of prunus rootstocks including St. Julien (plum and other stone
fruit, etc.):

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.
