What to Do About Excessive Vegetative Growth in Peppers? Practical Methods for Controlling Excessive Growth
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 goes in, which shows that the market for peppers is currently very good. However, many people have found that peppers often show excessive vegetative growth during cultivation, and this excessive growth causes pepper yields to drop rapidly. So what should be done about excessive vegetative growth in peppers? Let's take a look below!
1. Hanging String Regulation
Excessive vegetative growth in peppers is a common occurrence during pepper cultivation, and people use chemicals to control it when it happens. Methods such as managing fertilizer and water and reducing fruit set can also control excessive growth. In fact, hanging string regulation can also be used to control pepper growth, because sometimes the hanging strings in many growers' pepper greenhouses are very loose, while others are especially tight. In fact, this is not due to poor management: tightening the hanging strings can help weak peppers gradually recover their vigor, while looser strings can effectively control the growth rate of peppers and prevent excessive vegetative growth.
2. Temperature Control
Peppers are a warmth-loving crop, and the daytime growing temperature should preferably not be lower than 25 degrees, nor should it be lower than 15 at night. However, once pepper cultivation enters winter, farmers keep raising the greenhouse temperature to increase the growing temperature for 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 appropriately ventilate to lower the greenhouse temperature, and set up some shading facilities at the top to provide good shade.
3. Water and Fertilizer Management
After transplanting, peppers should be watered once with rooting water, but the amount of rooting water must be well controlled; too much will intensify the occurrence of excessive vegetative growth. Especially at noon in summer, when the temperature inside the greenhouse peaks and water evaporates faster, pay attention to controlling the amount when watering. Then, after transplanting, 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: use it sparingly or not at all, as nitrogen fertilizer is the main cause of excessive vegetative growth in peppers.
4. Rational Use of Chemicals ⟧11⟧When excessive vegetative growth is found in peppers, chemicals such as paclobutrazol can be appropriately used to inhibit plant growth. Those using chemicals for the first time should pay attention to the concentration and use them multiple times to work out the optimal concentration range. If excessive growth is found before hanging the strings, then chemicals should be used promptly to control plant growth and ensure the plant can set fruit normally later on. Record each chemical 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 strong and causing the plant to stop growing entirely.
Once you notice that the chili peppers are already showing signs of excessive vegetative growth, you can appropriately use chemicals to inhibit plant growth, such as paclobutrazol. Those using the chemical for the first time should pay attention to its concentration, and use it multiple times to work out the optimal concentration range. If you notice excessive vegetative growth before hanging the strings, then you must promptly use chemicals to control the plant's growth to ensure the plant can set fruit normally later on. Make a record each time you spray the chemical, then observe the plant's growth, and finally make adjustments. When spraying, be careful to spray the growing points, and do not spray too much on the same plant, to prevent the chemical from being too strong and causing the plant to stop growing entirely.
The above are the basic methods for controlling excessive vegetative growth in peppers. The first three are preventive methods, and the last is the use of chemicals for inhibition. Excessive vegetative growth in peppers prevents the lower leaves of the pepper plant from absorbing enough sunlight, leading to insufficient photosynthesis, which results in too little nutrient accumulation and lowers both yield and quality.
