What fertilizer is best for peppers?

The growth and development of peppers are affected by many factors, including soil conditions, environmental factors, and fertilization. Among them, the rational use of fertilizers is particularly critical to the growth of peppers. During the growth of peppers, the demand for potassium fertilizer and nitrogen fertilizer is relatively strong, while the demand for phosphorus fertilizer is relatively low. Let’s learn in detail what fertilizer is best for peppers ?

1. Fertilization of pepper seedlings

During the seedling stage of pepper, the amount of fertilizer applied accounts for 15% of the amount of fertilizer applied during the entire growth period . During this period, you can directly use balanced water-soluble fertilizer , or mix high-nitrogen water-soluble fertilizer with high-potassium water-soluble fertilizer and dilute it for irrigation. In addition, applying an appropriate amount of chelated calcium can help promote the growth of pepper seedlings.

2. Fertilize pepper during flowering period

The amount of fertilizer applied during the flowering period of pepper accounts for 35% of the total fertilizer application. Since peppers are more sensitive during the flowering period, the amount of water-soluble fertilizer needs to be gradually increased. And apply high-phosphorus water-soluble fertilizer one or two times when watering to promote the opening of flowers and fruit setting, and increase the fruit setting rate.

3. Fertilization during pepper harvest period

After the flowering period of peppers, the demand for fertilizers increases further, and the amount of fertilizer applied at this time accounts for 50% of the entire growth cycle. Since pepper is a plant that blooms and bears fruit at the same time, top dressing needs to be applied at the same time as harvesting. In the early stage, you can use high potassium and balanced water-soluble fertilizers, and in the later stage, you can add high nitrogen water-soluble fertilizers. During the harvest period, high-potassium water-soluble fertilizer can be used for topdressing to maintain plant growth and fruit quality.

4. Notes on pepper fertilization

Peppers are Solanaceous vegetables and are sensitive to chlorine, so chlorine-containing fertilizers such as potassium chloride and ammonium chloride should be avoided. Pepper seedlings have a small demand for fertilizers during the seedling stage, and excessive fertilization should be avoided, especially high-nitrogen fertilizers, so as not to cause excessive growth in the seedling stage and affect fruit setting in the later stage.

During the growth period of pepper, the demand for nitrogen fertilizer and potassium fertilizer is greater, while the demand for phosphorus fertilizer is relatively less. Therefore, it is necessary to reasonably control the ratio of nitrogen, phosphorus and potassium to ensure balanced growth of the plants.

During the entire growth cycle of peppers, although the amount of fertilizer is large, the principle of small amounts and multiple applications should be adopted during the topdressing process to avoid applying too much fertilizer at one time, so as not to affect the overall growth and yield of the peppers. Through scientific fertilization management, the yield and quality of peppers can be effectively improved.

In general, the fertilization strategy for peppers needs to be adjusted according to their different growth stages to ensure healthy growth of the plants and increase yield.
