Rose enthusiasts often encounter situations where their roses develop black stems or black branches, but they are at a loss as to why this happens or how to deal with it. Currently, the reasons for black stalks in roses are mostly speculative, although some enthusiasts have successfully found specific treatment methods.
There are generally two situations with black stalks in roses: one is from bottom to top, and the other is from top to bottom.
For black stalks that start from the bottom and go upwards, there is usually no hope of saving them. However, black stalks from top to bottom are not necessarily a disease but may be due to poor root establishment, where newly transplanted roses have not grown new roots, leading to black branches. Of course, there is another situation where new roots have grown, but black branches still occur. The treatment method for this situation is as follows:
Firstly, you must be ruthless in cutting off the blackened branches of the rose and preferably cut some of the normal branches below the black ones as well. Don't hesitate; the author has always been reluctant to cut, resulting in continuous blackening of the roses.
Secondly, the wounds of the roses should be sealed with wax as thoroughly as possible. The author found that after sealing the wounds with wax, even with continuous rain, the chance of further blackening is genuinely small, almost non-existent.
