How tall are potted grapes?

There are usually two shapes of potted grapes: one is suitable for small and medium-sized potted plants. In the year of planting, a bamboo pole or No.8 iron wire is erected in the center of the pot, and the height is about1m. After the new buds germinate, select strong new buds as main vines, pull them onto bamboo poles, and pick the core when they grow to 80-90 cm. After that, leave 1-2 leaves to grow except the top secondary buds. In winter, mature branches and vines can be cut off by 50cm. After germination in the second year, leave 3-5 strong new buds on the main vine, and the remaining buds should be erased in time. When pruning in winter, 2-3 buds are reserved for each new shoot as the bearing mother branch for pruning. After germination in the third year, each bearing mother branch leaves 1-2 new shoots, and then it is chopped every year. In the winter of the second fan-shaped planting year, the new shoots with a height of more than 60cm are cut as the trunk, and a new shoot is left every 10- 15 cm for oblique guidance in the following year. In winter, it is cut short as the fruiting mother branch with 1-3 buds, and in the third year, 1-2 fruiting branches are left on each fruiting mother branch, and new shoots and ear are bound.
