Budbreak inhibition and poor overwinter survival (OS) limit successful cutting propagation of  Acer rubrum October Glory, A. rubrum Red Sunset, Hamamelis vernalis, H. virginiana  and  Stewartia pseudocamellia.  Localized blanching (banding) of the cutting on the stock plant; a range of 3 IBA concentrations, and foliar spray application of: 1% silver thiosulfate(STS), STS followed ten days later by Gibberellin, GA 4/7 :250ppm(STS GA),50ppm thidiazuron (TDZ) and TDZ followed by GA 4/7  (TDZ GA)were tested for increasing growth and overwinter survival.. Carbohydrates were analyzed in cuttings which did and didn't grow.  A. rubrum October Glory * ,  and  Hamamelis spp  all had increased OS for cuttings which grew.  A. rubrum Red Sunset  demonstrated a similar trend.  Hamamelis spp.  had significant increase in carbohydrates for cuttings which  grew. A. rubrum October Glory'  exhibited the same trend.  S. pseudocamellia  did not have increased OS with growth. and showed no increases in carbohydrates with growth, but the cuttings that didn't grow had at least 93 % more carbohydrates than the other species analyzed. All species had higher OS when stored in the 3° C cooler, than in the fluctuating cold frame. Banding increased growth of  A. rubrum October Glory,  and  H. virginiana.  IBA concentration affected growth of all species. STS increased growth of  H. virginiana  and S.  pseudocamellia.  GA 4/7  increased growth of all cuttings except  A. rubrum October Glory.
