Management Methods for Potted Grapevines
The editor will explain the knowledge about potted grapevines, the management methods for potted grapevines. Next, the editor will introduce to everyone.
With the continuous improvement of people's living standards, more and more families live in apartments, and beautification has become increasingly important. Using a balcony to grow potted grapevines can vertically green and beautify the environment.
I. Variety Selection:
Generally, fresh food varieties with larger berries, beautiful fruit shapes, bright colors, compact clusters, and a certain ornamental period are suitable. Varieties such as Jufeng, Black珍珠, Seedless White, Seedless Purple, and Beauty Finger are recommended.
II. Potting Soil Selection:
Unglazed clay pots are ideal because they have minimal temperature changes, good water absorption, and breathability, which are beneficial for the growth of grape roots. The size of the pot depends on the number of fruits desired and the size of the plant. For example, if the diameter and depth are both 30 cm and managed properly, it can yield 3-5 kg of fruit. The best potting soil is loamy, fertile, well-aerated, moisture-retaining, and nutrient-retaining, with a neutral or slightly acidic humus soil.
III. Pruning and Shaping:
Potted grapevines have smaller root systems and should not have overly large plants. Fewer vines are better. Here are several ornamental shapes introduced.
1. Flowing Shape: Leave 60-100 cm of the trunk, with 3-5 fruiting branches above, each with 2-3 nodes cut. After branching, let them hang down naturally or place a 30 cm diameter iron circle on the surrounding posts, allowing the new shoots to wrap around the circle and hang down.
2. Fan Shape: Leave 60-80 cm of the trunk and 6-8 fruiting branches from top to bottom; each branch is cut to 2-3 nodes. After branching, tie the fruiting tops in a fan shape in order on the trellis.
The shape of potted grapevines should be compact. In winter pruning, the fruiting branches are mainly pruned short (usually left with 2-4 nodes). If the plant is weak, leaving 2 nodes on the new shoots is also fine. After forming a branch group, it should be updated in a timely manner.
For mature grapevines, after the plants sprout and unfold their leaves in the spring, generally one good bud is selected per node, and the rest are removed. When the shoots with inflorescences are revealed, they are planted. When selecting branches, it is preferable to leave the tender shoots with inflorescences at the base, making the position compact. For new shoots with inflorescences, they are pinched 3-5 days before flowering, the rest are removed, and the growing points of the tendrils are pinched off, leaving 3-4 leaves above the inflorescence to promote nutrient concentration during flowering.
Since the nutrient area of potted grapevines is controlled, it is necessary to adjust the load capacity in a timely manner to ensure good fruiting and tree growth. Try to cut off the top 1/3 a week before flowering, remove the secondary spikes, and thin flowers and fruits early.
The above information provides you with some knowledge and experience on the management methods for potted grapevines. I hope this article can be of some help to you!
