Pepper plants are usually a quite resistant, and they only require a minimal care. That is one of the reasons why many people love to have them in a garden. However, they are not fully immune to different infections, and there are some types of plant diseases that can harm them. Peppers need to have appropriate conditions for growing. It is the first requirement for their successful development. Like other plants, they cannot grow without water and Sun. Regardless of their health conditions, they have to be properly exposed to these elements. If they do not receive enough water or Sun, they would be weaker and therefore more susceptible to various illnesses.
Also, if chilies receive too much water on a daily basis, some disease may occur as an outcome. For example, excessive watering can attract Aphids, which are a real nightmare for chili plants. They are hard to spot at the beginning, and when you finally notice them, it is usually too late, and your garden is already partially or totally destroyed.
Also, poor pollination can be dangerous for peppers, and like misuse of water, it may cause different problems and attract various plant diseases. Some of these are Thrips, Viruses, and Spider Mites. Chemical injury can harm chilies too. It often attracts various illnesses, such as Powdery Mildew, Cercospora Leaf Spot, and Viruses among others. Temperature is also very important for pepper developing. Chilies may have a slow growth if it is too low. They may also fail to ripen because of the same reason. If you notice any of these symptoms, you would know what a potential cause is.
Eliminating the source will eventually cure your sick chilies. Always follow the basic rules to prevent any of these problems. Protect your pepper plants as good as you can. Use enough water and light. Adjust temperature. Expose your plants to sun rays. Use good soil and enough pollination. Avoid chemical injuries at all cost. It is all in your hands. If you create good conditions for your chilies, their illness will pass, and you will have no problems anymore.
