When is the best time to bag and unbag grapes
Abstract Grape bagging time: For open-field cultivated grapes in southern regions, bagging can be done promptly after fruit set following cluster trimming and berry thinning; while for greenhouse and rain-shelter cultivated grapes, bagging can be done 15-20 days after fruit set. Grape unbagging time: With traditional bagging, bags can be removed 10-15 days before harvest.
