Improper use of medicine plants are prone to drug damage, flower friends need to be careful.

Many beginners may not understand what drug harm is? Let me tell you about the drug damage is that after the use of drugs to the plant, the plant has some abnormal symptoms, in fact, it is somewhat similar to what we usually call "side effects". If you have a disease, you have to be treated, but the medicine should not be used indiscriminately. Improper use or improper dosage will cause damage to the plant.

How to tell whether there is a drug damage to the rose? If you pay more attention to the flowers, you will find that after you spray the leaves, there may be some grayish brown spots on the leaves, and the position of these spots coincides with the position of the drug residue. This happens more often after the use of drugs to kill red spiders.

Fertilizer is very important to maintain rose, it is best to choose ecologically safe organic fertilizer, nitrogen, phosphorus and potassium content is rich and balanced, adding a variety of organic matter, minerals, amino acids, promote plant rub, more buds, more flowering, long florescence.

This situation is the crux of the matter, and the reason for this situation is usually the use of medicine to the plant in the hot sun or high temperature. At this time, the high temperature coupled with the medicine may have a cauterizing effect on the branches and leaves, leaving some spots. These spots are telling you that the leaves have been burned! Not even on the branches.

In fact, the key point at this time is just to hurt the surface layer, the impact on the plant is still no big deal, but remind you to pay attention to the next medication. Of course, some of the more serious ones will dry scorch off the whole blade, which is a relatively rare and extreme example. It means that the concentration of your medication is too high. If you do not have a good grasp of the proportion of drug allocation, it should be a low proportion.

In order to maintain flowers, if you want to burst the pot, flowering more, fertilizer is very important, it is best to choose ecologically safe organic fertilizer, nitrogen, phosphorus and potassium content is rich and balanced, adding a variety of organic matter, minerals, amino acids, promoting plant rub growth, gestating more buds, more flowering, long flowering period.

At this point, many flower friends will have doubts, not to say that spraying pesticides at a high temperature is more effective. I can only say that this is true in terms of reason, but it is also determined according to the actual situation. For example, if you are spraying a big tree with insecticide, there is no problem with choosing to do it in the scorching sun.

Because big trees have strong resistance and many insect pests, luxuriant branches and leaves have reduced the sunshine rate of branches and leaves to a certain extent, even if there is a disease, it will not be too serious. And some small potted plants, to take into account the bearing capacity of the plant, please try to choose when the sun is mild, otherwise it is easy to cause adverse harm to the plant.
