What is the best method to make grapes sweeter?
For many girls, what is the best method to make grapes sweeter and the green plant flower aspects of the tips for making grapes sweeter, let's find out together below.
Grapes are an economic fruit with many varieties and a wide planting area. Varieties such as Jufeng and Hongdi are loved for their sweet and sour taste, crispness, and juicy flesh, and have remained popular over time.
From focusing on yield to gradually focusing on quality: previously, when people planted grapes, it was a matter of pride to have a higher yield than others in the same area. However, with the development of the economy, people's pursuit of fresh food has reached a new level, and the improvement in living standards has made consumers more focused on taste and freshness!
Nowadays, grapes are about to hit the market in large quantities, and during the last stage of growth, how to increase sweetness has become a crucial task. If left unmanaged, focusing only on the yield of grapes may result in them not being able to sell at a high price or even fail to sell.
My Xiahei grapes in the cold greenhouse are now in the color-changing stage, where a cluster of grapes may have three colors: green, red, and purple-black. The color-changing stage is a good time to increase sweetness. Today, I will mention some methods to make grapes sweeter, hoping to provide a reference for everyone.
Apply fertilizer to enhance sweetness: I recommend using ripe farmyard manure as the main ingredient and chemical fertilizers like urea as a supplement to increase the sweetness of grapes. Friends can also spray foliar fertilizers to assist in making grapes sweeter.
Increase potassium or phosphorus fertilizer to achieve a sweetening effect!
A: Potassium fertilizer mainly promotes stem growth.
B: Phosphorus fertilizer mainly promotes root growth in the early stages of plant growth and acts on fruits and seeds in the later stages.
Therefore, spraying 0.3% to 0.5% phosphorus acid potassium or 4% to 6% wood ash extract solution on grapes during the swelling stage may increase the sweetness of the grapes by 1 to 2 degrees.

Control yield to enhance sweetness: This is usually very easy for experienced gardeners, who can estimate how many clusters of grapes to keep on a vine, how many grapes to keep on a fruiting spike, and how much yield per mu, etc., based on the vine's condition. Never focus on quantity; quality should be the priority.
In spring, when葡萄 (grapes) sprout new branches, we remove buds and set branches, usually leaving 1-2-year-old fruiting branches.
Next is the grape topping treatment, leaving a certain amount of leaves, secondary branches with 6-7 leaves, and topping! After the secondary branches grow, leave 1-2 leaves and then top again! The benefits of this: the leaves left can meet the growth needs of the fruit and also increase the sweetness of the grapes! (For specific topping methods, you can refer to the Xiaoyang grape video)
In fact, what we mean by controlling yield is to manage properly and thin fruit in a timely manner. Ensuring that nutrients can flow back into the fruit will improve the quality of the remaining fruit.
Sunlight: The sun is the source of production for plants and animals in nature, and grapes are a light-loving plant. Grapes with sufficient sunlight grow better and have a sweeter taste compared to those that do not receive sunlight.
Adequate sunlight results in thicker leaves, robust plants, and better quality, while insufficient sunlight has the opposite effect! Therefore, what we can do includes: paying attention to summer branch and leaf management, fully utilizing direct sunlight, and also choosing to use reflected sunlight, with some orchards laying reflective films.
