What type of fertilizer is best for chili peppers
An article provides detailed information about the best fertilizer for chili peppers in the field of horticulture. Below, the editor will explain in detail for you.
What type of fertilizer is best for chili peppers
Fertilizing chili peppers usually requires selecting different fertilizers based on different fertilizing times. Generally, a base fertilizer should be applied at the time of planting, with organic fertilizer and calcium superphosphate being a good choice as a base fertilizer, and a certain amount of potassium sulfate should also be added. If top dressing is done during the seedling stage of chili peppers, using organic fertilizer and calcium superphosphate is better, but the amount should be much less; if foliar dressing is done, it mainly occurs during the flowering and fruiting stage, with urea and potassium dihydrogen phosphate being suitable for spray application.
Overview of Chili Pepper Fertilization
Chili peppers are a species of Solanaceae, Capsicum annuum. The optimal germination temperature for seeds is between 25-30 degrees Celsius, and the optimal growth temperature is between 15-34 degrees Celsius. They are neither drought-tolerant nor flood-tolerant.
Chili peppers have a high demand for fertilizers during growth. Generally, nitrogen, phosphorus, and potassium fertilizers are required, as well as fertilizers containing trace elements such as calcium, magnesium, iron, boron, copper, and zinc.

How to fertilize chili peppers
When fertilizing chili peppers, it is important to control the amount of fertilizer. If too much fertilizer is applied, or if concentrated or raw fertilizer is used, it can burn the roots and affect plant growth. Additionally, it is necessary to top-dress chili peppers appropriately and avoid applying excessive nitrogen fertilizer to prevent excessive growth.
Base fertilizer: The base fertilizer for chili peppers is usually applied to the soil before planting. The method is to first evenly spread the fertilizer on the soil surface and then incorporate it into the soil by plowing, which can better utilize the fertilizer efficiency.
Top-dressing: For top-dressing chili peppers, if it is organic fertilizer, it can be directly poured into the soil, if it is granular fertilizer, it needs to be buried in the soil, and foliar fertilizer only needs to be sprayed on the leaves.
Spring FertilizationSummer fertilization is best done in mid-to-late May, mainly applying phosphorus fertilizer. If there is a phosphorus deficiency, it can easily cause blossom and bud drop, so it is necessary to apply phosphorus fertilizer appropriately.
Autumn FertilizationAutumn fertilization is generally done in August, with potassium fertilizer being the main requirement for the plant. If potassium is insufficient, there may be leaf drop and low fruit-setting rate, leading to low yield of chili peppers, so it is necessary to ensure adequate potassium.
Winter FertilizationWinter fertilization is around November, mainly applying calcium fertilizer for chili peppers. If the plant lacks calcium, it can lead to fruit rot and fruit drop, so it is necessary to supplement calcium adequately.
Key Points to Note When Fertilizing Chili Peppers
1. To prevent root burn from fertilizer damage, foliar spraying with plant growth regulators or drenching can be used, or natural brassinolide emulsion can be applied for foliar spraying and drenching, which is quite effective.
2. If chili peppers lack boron, their leaves will turn yellow, and the plant growth will slow down, leading to delayed flowering and significantly affecting yield. Therefore, to prevent leaf yellowing, more boron fertilizer should be applied.
