Is it normal for the bud point to be black when the tree-shaped rose is cut and the rose stem is grafted?

It is normal to graft tree-shaped roses with cuttage rose stems, because grafting requires high survival rate, good rootstock activity and strong grafted buds. On the one hand, problems will lead to black stems and black buds.

For example, some roses have thin styles and poor resistance. Even if they are cut, they are likely to be black and have no buds. For example, two rose poles I bought last winter were managed and cut in the same way. As a result, the survival rate of one pole was over 95%, the survival rate of the other was less than half, and some poles were black and rotten at the same time. Therefore, choosing a strong and active rootstock is the first choice. Personally, I recommend the rose stem with white flowers and no thorns as a tree rose.

The picture below is not a cactus, but a decorated rose. It looks like a cactus after being cut. Tree-shaped roses look interesting and have certain scientific and academic value.

The second point that many novice flower lovers can't solve is the optimization of scion. Generally, flower lovers will choose some buds from their own potted roses for cutting. In fact, sometimes there is a huge difference in plumpness between different bud points, and the bud point used for tree-shaped roses grafted in nursery is the most plump, so the grafting survival rate is high, and it is difficult for ordinary flower lovers to choose bud points in this way. As long as there are buds, there is no choice. So the tree-shaped roses grafted in the nursery have a high survival rate.

The girl lollipop I grafted below is the so-called bud point is not technical enough, together.

It is very important to do a good job of disinfection when cutting rose stems, especially for poor quality rose stems. If the two poles are rich in nutrition and good in quality, sterilization seems dispensable. Usually, I am sterilized with hymexazol. For example, I use fine coconut bran to cut rose stems. After the coconut bran was put into a pot, I poured it once with 1500 times liquid, and the raw rose stems were soaked. After cutting, spray bactericide as a whole to be foolproof. The blackened pole basically loses its value. If only the bud is blackened, you can continue to patch it, no problem at all.
