Lake County Pruning School is an immersive training program delivered by Simonit & Sirch. Vine Master Pruner Jacopo Miolo will share knowledge about grapevine sap flow and teach innovative pruning techniques to foster grapevine health, longevity, and sustainability of the vineyard.

Four fundamental principles applicable to all grapevine training systems will be covered in depth:

  1. CONTROLLED BRANCHING – Drive the development while respecting the vine’s organic growth.
  2. VASCULAR FLOW – Separate desiccated areas of the main vascular flow and ensure continuity of the sap flow through the structure of the plant.
  3. CUTS & CROWN BUDS – Reduce the surface area of the exposed wound and lessen the risk of wood disease.
  4. PROTECTIVE SPARE WOOD – Prevent desiccation of the vine.

Lake County Pruning School comprises a theoretical introductory online lesson and three days of practical hands-on lessons in the vineyard (two days during the winter for vine pruning and one day during the spring for shoot thinning).
