What to Do About Excessive Vigorous Growth in Peppers? The Latest Method for Controlling Vigorous Growth Is Here
As an essential side ingredient in our daily lives, peppers are extremely popular in provinces such as Sichuan and Hunan. No matter what dish is being stir-fried, a little pepper must be added, which shows that the current market for peppers is still very good. However, many people have found that during the cultivation of peppers, excessive vigorous growth often occurs, and vigorous growth causes pepper yields to drop rapidly. So what should be done about vigorous growth in peppers? Let's take a look below!
1. Regulation by Hanging Strings
Vigorous growth in peppers is a common phenomenon during pepper cultivation. When peppers grow too vigorously, people use chemicals, manage fertilizer and water, reduce fruit set, and other methods to control the growth. In fact, hanging strings can also be used to regulate and control pepper growth, because sometimes many friends' pepper greenhouses have some hanging strings that are very loose, while others are especially tight. In fact, this is not due to improper management; rather, tightening the hanging strings can help weak-growing peppers gradually recover their growth, while looser strings can effectively control the growth rate of peppers and prevent vigorous growth.

Peppers are a temperature-loving crop. During the day, the growing temperature should preferably not be lower than 25 degrees, and at night it should not be lower than 15. However, after pepper cultivation enters winter, farmers keep raising the greenhouse temperature in order to increase the growing temperature of peppers, causing the greenhouse temperature to become too high. When the temperature is too high, it not only increases flower and fruit drop in peppers, but also hinders flower bud differentiation and favors the onset of viral diseases. We can properly ventilate to lower the greenhouse temperature, and set up certain shading facilities at the top to do a good job of shading.
3. Water and Fertilizer Management
After peppers are planted, they should be watered once with settling water, but the amount of settling water must be well controlled; too much will intensify the occurrence of vigorous growth. Especially at noon in summer, when the temperature inside the greenhouse peaks and the evaporation rate of water becomes faster, pay attention to controlling the amount when watering. Then after planting, apply a seedling-stabilizing fertilizer once to stabilize the growth of the seedlings and promote root development. However, after peppers enter the fruiting stage, pay attention to the use of nitrogen fertilizer and use it sparingly or not at all; nitrogen fertilizer is the main cause of vigorous growth in peppers.
4. Rational Use of Chemicals
When it is found that peppers are already showing vigorous growth, chemicals such as paclobutrazol can be appropriately used to inhibit plant growth. Those using the chemical for the first time should pay attention to the concentration and use it multiple times to work out the optimal concentration range. If vigorous growth is found before hanging strings, then the chemical should be used in time to control plant growth and ensure that the plants can set fruit normally later. Make a record after each spraying, then observe the plant's growth, and finally make adjustments. When spraying, pay attention to spraying the growing points, and do not spray too much on the same plant, to prevent the chemical's potency from being too high and causing the plant to stop growing directly.
The above are the basic methods for controlling vigorous growth in peppers. The first three are preventive methods, and the last is the use of chemicals to inhibit growth. Vigorous growth in peppers causes the leaves at the bottom of the pepper plant to be unable to absorb enough sunlight, resulting in insufficient photosynthesis, which leads to too little nutrient accumulation and reduces yield and quality.
