What to do when black spots on roses increase
Some netizens have asked me what to do when there are too many black spots on the leaves of roses. I'll teach you a trick to solve it easily.
1. Check the leaves
If it's really serious, we need to cut it off and clean it up. After cleaning it up, dilute it 500 times and then spray it on. When spraying, make sure to spray both sides, including the soil and pot walls. This can effectively treat it. It's best to spray twice every five days. The new leaves that grow later will not have black spots.
Benzoylpyrazole can also treat various spot diseases, including powdery mildew. It can be said that its effect is very broad. However, the following nursing environment must be paid attention to. For example, in a humid environment, ventilation should be enhanced to reduce the bacteria and later reduce the disease.

The light should not be too strong, as strong light can easily cause leaf burning, which is sunburn. Therefore, everyone must remember this method to make the roses grow well, and the black spots will disappear.
