#HOWTOCOVERGRAPES #GRAPES This video shows how I cover Preobrazhenie grapes for the winter. I remove the leaves near the Preobrazhenie grape bush, lay the Preobrazhenie grapes on the ground, pin the Preobrazhenie grapes to the ground with pins, treat the Preobrazhenie grapes with iron sulfate, and cover the Preobrazhenie grapes with 50% agrofibre.
