What is the best fertilizer for chili plant top-dressing
For most women, the content of what is the best fertilizer for chili plant top-dressing in the aspect of green plants and flowers, let's get to know together.
What is the best fertilizer for chili plant top-dressing
Chili plants have high fertilizer requirements. From seedling emergence to bud formation, they need less nutrients. From bud formation to initial flowering, plant growth accelerates, and the demand for nutrients increases. From initial flowering to full bloom, the fruiting period is vigorous, and nitrogen fertilizer needs to be top-dressed at this time. From full bloom to maturity, phosphorus and potassium fertilizers should be increased. After harvesting mature fruits, nitrogenous fertilizer needs to be applied. Calcium fertilizer should be supplemented before flowering and during the fruiting period.
Timing for chili plant top-dressing
1. Chili plants absorb different amounts of nitrogen, phosphorus, potassium, and other nutrients at different growth stages. From seedling emergence to bud formation, the number of leaves is small, and the accumulation of dry matter is slow, hence the need for nutrients is low.
2. After transplanting, chili plants can be top-dressed once when watering the plants, applying a small amount of water-soluble phosphorus, which is beneficial for the growth of new roots and can improve survival rates.
What type of fertilizer to use for chili plant top-dressing
Chili plants have high fertilizer requirements. From seedling emergence to bud formation, they need less nutrients. From bud formation to initial flowering, plant growth accelerates, and the demand for nutrients increases.

From full bloom to maturity, phosphorus and potassium fertilizers should be increased, and after harvesting mature fruits, nitrogenous fertilizer needs to be applied.
Should chili plant top-dressing use urea or compound fertilizer
When top-dressing chili plants, urea and compound fertilizers can be used. Urea is a basic fertilizer that can supplement the nitrogen needed by chili plants. Chili is a crop high in nitrogen and potassium and medium in phosphorus. To ensure sufficient nutrient content, compound fertilizers must be used. Chili can be harvested multiple times after maturation, and a large amount of top-dressing is needed in the mid-late stages.
Methods for chili plant top-dressing
First application: After chili plants have survived, the first top-dressing can be done by applying a solution of ammonium sulfate.
Second application: When chili plants form buds, dilute human waste or calcium sulfate to make a solution for root irrigation.
Third application: In May, when the first cluster of fruits begins to grow, a lot of nutrients are needed, and fast-acting fertilizers should be used. Apply human waste or ammonium sulfate, mix the above fertilizers evenly, apply them in strips or holes, and then water.
Fourth application: In June, when temperatures are high, it is a period of vigorous growth. The amount of fertilizer and method of application can follow the third top-dressing.
Fifth application: In August, when the weather is hot, chili growth slows down, leaf color is light green, fruits are small and fewer, human waste or ammonium sulfate solution can be applied.
Sixth application: In September, a top-dressing can be done, with the amount and method of application following the fifth, which can increase yield.
Precautions for chili plant top-dressing
Before chili plants bloom, the frequency of fertilization can be reduced, otherwise it can cause excessive growth and result in blossom and fruit drop. Chili is a potassium-loving crop. Sufficient potassium fertilizer should be applied at the end of flowering, fruiting, and before maturity. It is best to use fast-acting, water-soluble, safe, and environmentally friendly chelated high-potassium water-soluble fertilizers. Calcium fertilizer should be supplemented before flowering and during the fruiting period, depending on the soil conditions of the planting area.
