Main pestsAphids are a very common pest. They will eat stems and leaves. No matter whether they are black or green, they are very harmful and can be said to be the number one killer in the plant kingdom. Another reason why they are so widely distributed is that female insects can reproduce right after they are born and do not need males at all. And in the animal kingdom, it is the only one that can synthesize pigments. They will constantly gnaw on the stems and leaves to absorb nutrients, and they will also spread diseases in the process. This is because they do not only "bite" this one plant, so they will bring diseases of other plants to the sea daffodil. Pest ControlIf you encounter this kind of insect, you must deal with it in time to avoid it becoming a disaster. But don't be afraid, if you handle it properly, there will be no problem. If you find this kind of insect just after it appears, you are lucky. You just need to remove the small insect that has appeared and then spray the medicine. Main diseasesThe most common disease of this plant is that the leaves change color and fall off. This may be caused by root rot or excessive fertilizer. Root rot is mainly caused by excessive watering, which causes water accumulation in the soil. The roots will rot, causing the leaves to fall off, or even the whole plant to die. Too much fertilizer can easily cause fertilizer damage, so you must be careful. Disease controlThe diseases that occur need to be prevented and controlled according to the causes of their occurrence. From the above we can know that water and fertilizer cannot be excessive. If you choose to plant them outdoors, you must do a good job of rain prevention and drainage when there is a lot of rain to avoid causing harm to them. |
