Why do chili peppers go into summer dormancy? Causes and control methods

During summer chili pepper cultivation, a phenomenon often occurs, namely summer dormancy, in which the plants hardly grow and also show symptoms such as yellowing leaves, being very prone to flower and fruit drop, and stiff fruit. So why do chili peppers develop summer dormancy? Let's take a look together.

I. Causes of chili pepper summer dormancy

Summer temperatures are hot, and at this time not only do people experience loss of appetite, livestock also show a decline in feed intake, and plants also show symptoms of slow growth. For chili peppers, the fruiting position is far from the main stem, and combined with the relatively high temperature, the plant's growth vigor becomes weaker and weaker, resulting in summer dormancy.

II. Control methods

1. Supplement water in time

In summer, not only does the soil evaporate faster than before, but leaf transpiration also increases. Once the plant lacks water, the leaves will turn yellow and withered, affecting the formation of photosynthetic products, so water must be supplemented in time in summer. However, watering also requires care: watering should not be done at noon when the sun is at its strongest, as this may scorch the leaves; it is best done in the morning when the temperature is lower. Watering must be done with a small amount of water, and be sure not to flood-irrigate, which would cause the soil to become waterlogged.

2. Reasonable fertilization

Chili peppers need a relatively large amount of nutrients during the fruiting period, to satisfy both their reproductive growth and vegetative growth, so after entering the fruiting period they should be fertilized frequently, especially after entering the dog days. Fertilization during the chili pepper fruiting period is mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer. After picking one crop, water and fertilize to replenish nutrients and water.

3. Pinching and topping

Chili peppers should be topped and pinched in time during growth. The purpose of doing this is to promote the emergence of side branches and avoid the chili pepper fruiting position being too far from the main stem, which would affect nutrient absorption. When planting, topping and pinching must be done multiple times, generally once every half month. The principle of topping and pinching is that each fruit has two leaves.

4. Remove old leaves

During the continuous growth of chili peppers, the old leaves on the lower part should be removed in time, which can save nutrients, and diseased branches and leaves should also be removed in time.
