The best time for bagging Kyoho grape is after fruit setting is stable. It is best to do it after the fruit can stand a certain high temperature weather, avoiding rainy weather, and it is most suitable to do it on a sunny day after heavy rain. Or wrap the bag before the rainy weather comes, which can avoid infection or reduce the risk of being burned by the sun. In short, it is carried out in good weather after the fruit is ripe.

The early bagging orchard can be carried out as early as after the grapes have set fruit and the work of thinning flowers and setting fruit has been completed. Orchards with early rainy season and heavy rainfall, early-maturing varieties and easily cracked fruit varieties are suitable for early bagging.

The later bagging of the orchard can be completed before the rainy season, and at the latest when the berries are colored. Orchards with late rainy season and less precipitation, late-maturing varieties and varieties with strong crack resistance are suitable for late bagging.

When all conditions are met, bagging should be done sooner rather than later, and bagging is too late, which will easily lead to sunburn, insect pests and fruit rot.
