Propagate Prunus Rootstocks


European growers have for over fifty years used the Basal Long Soak 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  Hortus IBA Water Soluble Salts (100 ppm as IBA) 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.
