The day before yesterday, I met a flower friend and asked the blue demon that his rose branches had blackened. I don't know what the reason was and how to deal with it.

Rose black pole do not know if you have encountered? Today, the blue demon will talk about the reasons and ways to deal with the rose black pole.

The reason for the black pole of the rose

The occurrence of black pole in rose is a kind of morbid, so we call it black rot.

Black rot has a high incidence in summer and early autumn, which is mainly caused by improper fertilization and bacterial infection. We take different ways to deal with different situations of black pole.

Black rot from the bottom up

The bottom-up black rod mainly occurs in the hot summer, when the rose is mostly dormant or semi-dormant, and has little demand for fertilizer and water. If you fertilize the rose at this time, it is easy to cause fertilizer damage and damage the root system of the rose. And then show the black rod.

This kind of bottom-up black pole, because it starts from the root, so it is more troublesome to deal with it, and it is necessary to wash the roots of the whole rose.

Then clean the black rot, soak carbendazim for easy disinfection, soak the rooting powder, and then replant it with clean soil.

The whole process is still quite testing, for novice flower friends, the success rate is low.

This is about the bottom-up black pole situation, and the other case is easier to deal with.

Top-down black pole

The top-down black pole of rose is mostly caused by infection of germs, or excessive aging of branches, or in an unventilated environment.

For the top-down rose black pole, the treatment method is very simple, as long as the black pole is completely cut off.

Note that when cutting, you must take the healthy branches around the 5cm to cut off together, do not be reluctant, if the cut is not thorough, the black pole will appear again, so you must be ruthless and completely eliminate the source of the disease.

Note:

It should be noted that there is another situation that does not need to be dealt with in the top-down black rod of the rose, that is, if there is a top-down black rod in the newly transplanted rose, it does not need to be dealt with, which is a normal phenomenon of slow seedling of the rose.
