What is the Best Trellis Shape for Sunlight Rose Grapes
Here is a comprehensive analysis of the best trellis shape for growing Sunlight Rose grapes, with specific details as follows:
What is the Best Trellis Shape for Sunlight Rose Grapes
Sunlight Rose grapes are a common variety of grapes. When planting them, it is necessary to build a trellis to support their growth. Currently, there are three main types of trellises for Sunlight Rose grapes: the "V" shape trellis, the horizontal pergola, and the dwarf espalier. Generally, posts, wires, and shelters should be designed around the chosen trellis shape. If the trellis shape has to adapt to them, it becomes passive and difficult to build, making the design of the trellis very important.
Shape of Sunlight Rose Grapes
Currently, there are two main shapes of Sunlight Rose grapes, each with its own advantages, with the ratio of fruit-setting agents having a greater impact, but it is not absolute.
1. Round with a Belly Button
This shape is actually caused by an excessive amount of thidiazuron during fruit-setting. It is also common in trees with moderate to weak growth and late flowering. The advantages are large size, thick skin, and high sugar content. The disadvantages include difficulty in skin color fading and not obvious fruit aroma, which makes it hard to showcase the sugar content advantage.
2. Round and Long Agate Shape
This shape is caused by a bias towards gibberellic acid and benzyladenine in the fruit-setting agents. With less addition of chlorpyridate, the fruit grains tend to be longer, and with more addition, they are rounder. The advantage of this shape is that it retains the original aroma and taste, but the disadvantage is that the size is not prominent and the fruit rust is heavy.
Reasonably formulating fruit enlargement agents to address the pros and cons of fruit-setting agents can effectively solve issues related to fruit shape. Currently, such technology is quite mature.
Trellis Shape for Sunlight Rose Grapes
There are currently three main types of trellises for Sunlight Rose grapes, each with its own advantages and disadvantages.
1. Horizontal Pergola
The advantage of this trellis is that the fruit has almost no sunny or shady sides, and the overall quality of the fruit cluster is good, with relatively simple and uniform flowering.
The disadvantage is that it can be tiring to work with the neck craned and arms raised. Moreover, if the trellis is too large, the load capacity must be high, requiring a large root system. The walking area is compacted, limiting the expansion of roots, so the trellis should match the line where the feet are placed and should not be too large.
2. V-Shaped Trellis
The advantage of this trellis is that it has a lighter sunny or shady side. Even if the binding is late, flowering is not difficult. It can be high or low, allowing for sitting or standing work. The angle of the chest can be large or small, which is currently my favorite trellis. The sunny or shady side can be resolved by using colored bags late and coloring inside the bags.
3. Dwarf Espalier
The traditional trellis in the north. Currently, the sunny or shady side is indeed a problem, and the low fruiting position also makes the white rot disease more severe, so it is no longer recommended.
