Rose flowering is very beautiful, but it is also easy to be infected with diseases and insect pests, so in the family potted rose planting, what matters should be paid attention to? Today, let's talk about several diseases and insect pests that are easy to be infected by rose. The following is an introduction to the common diseases and insect pests of rose and their control methods.

Family potted rose is generally placed on the balcony for maintenance, because of ventilation, temperature, light and other conditions, it is most vulnerable to the damage of red spiders, especially dry air, dry soil and other factors, are relatively easy to infect red spiders. Therefore, we usually need to pay attention to increase air humidity, and just by cutting off the branches infected with red spiders is useless, must be used to kill red spiders.

In addition to the red spider, powdery mildew is also a disease easily infected by the rose, which is mainly caused by poor ventilation, rainy weather and hot and humid environment. Of course, powdery mildew can also occur if the environment is very dry. There is also black spot, which first grows a small spot from the leaf, which turns purple, black or brown, and then slowly expands, eventually causing the whole branch to dry up. It may even lead to the death of the rose.

Speaking of rose, there are too many diseases and insect pests, but some of them are caused by external factors, and some of them are caused by their own poor resistance, so if we find that the plant is relatively short or malnourished, we should always replenish it with fertilizer. Powdery mildew, for example, may be a sign of calcium deficiency and potassium deficiency. We can add more fertilizer to it and improve its resistance.

So, what are the ways to deal with these diseases and insect pests in potted rose? First of all, the branches infected with diseases and insect pests should be cut off, and then they should be sprayed with special drugs to ensure that they can return to normal growth. At the same time, we usually have to provide it with a comfortable growth environment to avoid being infected with diseases and insect pests.
