Which month is suitable for grafting roses (Can roses be grafted in December)

Can roses be grafted in December?

It is December now, and most parts of the country have entered winter. In addition, the temperature in our area has been dropping in the past few days, with the lowest temperature around zero degrees.

A friend in Hebei said that the local temperature is already minus 8 degrees Celsius. Can we still graft roses in such weather? The answer is yes. Although grafting roses in winter is not the best, it is still possible.

The best seasons to plant roses for grafting are spring and autumn. In spring, everything comes back to life and the temperature rises. Roses begin to enter a rapid growth period. At this time, when we graft roses, the activity of the rootstock and the scion is relatively strong.

As long as you master the basic principles of grafting and align the cambium, the buds of the scion will sprout quickly, it is easy to graft and the scion grows faster . After the graft survives, the buds will grow branches and bloom in the season, which is also a big advantage of spring grafting.

However, there are also disadvantages to spring grafting. The rains are continuous in spring, and if the joints are not well protected, they are prone to infection. In spring, plants begin to recover, bacteria also become active, and the joints are relatively more susceptible to infection.

Therefore, when we graft again, we must pay attention to the disinfection of props. We can use carbendazim, benomyl solution or potassium permanganate for disinfection. In addition, the grafted buds should be wrapped with plastic bags to prevent rainwater from entering.

The best time for autumn grafting is around October, when the temperature is not high, the grafted grass is not likely to turn black, and the buds are not likely to dry out.

Moreover, the rose has not yet begun to dormant at this time, but is still growing and blooming vigorously. The grafting survival rate is very high. As long as you have some basic knowledge, the grafting can basically survive, and any method can be used.

The worst thing is grafting in summer. It is recommended that you do not do it in summer as the survival rate is very low and it is easy to turn black.

Not only are the buds prone to drying up, but the rootstock may also be infected with black stems because of the cut. If it is not cut off in time, the entire stem can become black, which is simply "losing both the wife and the army". Therefore, if you are not in a hurry, it is recommended that you do not graft in the summer.

Grafting is also possible in winter. I grafted quite a few roses in the past few days, including a tree rose and a multi-colored rose, and they are in good condition now.

For winter grafting, I recommend that you use chip bud grafting, because the survival rate of chip bud grafting is very high when used on roses, and this method is also used for grafting many fruit trees.

Although there are many grafting methods, this method is simple to operate and has a high survival rate, and novices can master it well. After grafting in winter, it is recommended to tie the buds in the grafting tape and do not expose them.

Don't let it grow for the time being. The weather is cold and the buds will not grow well. Tie it up first. Wait until the spring when the weather is warmer and then remove the film. Cut off the reserved rootstock branches, and the buds will grow all of a sudden.

There is a disadvantage of winter grafting, that is, the rootstock and scion have begun to dormant and are not very active. If you want to see the effect immediately after grafting, it is impossible.

If you graft it now, the bud will not grow well until spring. You can only see the effect in spring. In the nursery, grafting is basically done in winter, and rose stems are grafted by cuttings. This operation is very efficient and has a high survival rate.

Therefore, if you want to graft in December, you can still do it now. Just pay attention to protecting the buds, and leave the rest to time.
