What are the methods for bagging grapes? A detailed explanation of the key operational points
What methods are there for bagging grapes, and what are the benefits of bagging? To enhance the market competitiveness of grapes, promoting and applying bagging technology on grapes has become a consensus among growers, but how can the benefits of bagging be maximized? Preparation before bagging: 1 week before flowering, trim the flower clusters; for large clusters, remove the secondary clusters and 1 to 8 branch axes at the base of the main axis; for small clusters, remove few or none; pinch off about 1/4 of the cluster tip before flowering; thin the berries 2 weeks after fruit set, starting immediately once the fruit has set steadily, and finish before the rainy season arrives.

Bagging method: When bagging, first use your hands to open the paper bag so that the whole bag puffs out, then from bottom to top put the entire fruit cluster into the bag, then gather the bag opening onto the stalk and tightly tie it with the sealing wire on one side. However, leave 1.0 to 1.5 cm of the paper bag above the sealing wire, and absolutely do not rub the fruit cluster with your hands.
Timing for removing the bag: After bagging, the bag may be left on and the fruit harvested with the bag; generally, red varieties can have the bag removed about 10 days before harvest to promote good coloring. However, if the fruit cluster inside the bag is coloring very well and is already close to the best commercial color tone, then there is no need to remove the bag, otherwise the purple color will deepen and the coloring will be excessive.
