The petals are purple red and shaped like inverted egg wedge. The flowering time is from March to June, and the fruit ripening time is from April to July. Before, it was usually planted in the deep mountains. Because of its beautiful appearance, it was used as an ornamental in the gardens. But in the maintenance of it, we also need to pay attention to a lot of problems, especially diseases and insect pests. If there are any, how to control them? Let's see.

1. White silk disease

When it is raised, the disease often occurs, especially in the rainy season. At the beginning of the disease, its leaf base is covered with some white hyphae, which will also make its roots rot. So it's hateful. According to this time, we can remove the soil in the basin with bacteria, and then sprinkle a layer of lime powder to solve the problem. But the so-called cure is not cure the root, if you want to completely cure, you still need to pay attention to the usual ventilation, basin soil drainage is also good. If there are some serious diseases, we must burn them.

2. Anthrax

This kind of disease exists all the year round, so it is also more painful. It is generally more severe in rainy seasons with higher temperature. This disease starts from the top of its leaf tip to the root, which is brown at the beginning, and then it will gradually increase, with a lot of small black spots, which will cause the whole plant to die when it is serious. Then we need to use a certain chemical agent spray control, so that it can be completely killed, in addition to actively improve some environmental conditions is also helpful.

3. Sheath rust

It is also a common disease, which usually occurs on the upper and lower sides of the leaves. Some of the blisters appear on the stems, and even there are powdery spores of yellow, orange and other colors. This disease looks scary, but it will not directly harm them, and the leaves will not die, but it will make its real plants grow very slowly, which is also very painful. The prevention and treatment we need to do at this time is, on the one hand, we can cut off those sick leaves, on the other hand, we need to spray with some drugs, so that it can be prevented and treated.

4. Scale insects

A very annoying pest. I believe that many of us have seen it. It usually occurs when the temperature is relatively high or the air circulation is not smooth. It can reproduce very fast, so it needs to be treated earlier. If it is more, it needs to be sprayed with drugs. If it is less, it can be removed manually.
