When to propagate roses
Do you know this? Introduction to the related knowledge of rose cutting and the season and method of cutting green plants and flowers, let's follow the editor to see!
Roses are about to enter the blooming period. After enjoying the beautiful flowers, we can start trying to cut them. This is the best time for rose cutting, not only with a high rooting rate but also very fast rooting speed. Most importantly, the branches at this stage are very vigorous, which is very suitable for cutting.
So, if you want to be a green thumb, you might as well try it now. Today, Mu Mu mainly introduces the reasons why cuttings die and briefly introduces the cutting method.
One: Why don't rose cuttings root?
Most rose growers have tried rose cutting, and rose cutting is a very simple task. However, most of the growers who have tried it have failed. So, what is the reason? First, let's talk about why rose cuttings don't root.
1: Incorrect timing
First of all, for beginner growers, not all times are suitable for cutting, for example, high temperatures in summer and extreme cold in winter are not suitable times for rose cutting.
The time for rose cutting usually concentrates after spring and autumn flowering. At this time, the branches are not only the most vigorous but also have the right thickness, and the temperature for cutting is very suitable, not only suitable for rooting but also preventing branches from rotting due to high temperatures or dormant due to low temperatures.
It is generally recommended to cut from the end of April to the beginning of May in spring and the end of October in autumn.
2: Unsuitable branches
In addition to the timing of cutting, the branches for cutting are also very important.
If the branches are too thick, rooting will become very slow. If the branches are very thin, although rooting is faster, later maintenance will be very troublesome, and this rose is destined to start as a weak seedling.
If the branches are too tender, they may quickly wither or even die due to immaturity after cutting. However, if very hard lignified branches are used for cutting, the rooting speed will also be very slow or only form healing tissue. Therefore, whether the branches are suitable and which branches to choose are very important.
Try to choose semi-lignified green branches after flowering for cutting, with a thickness similar to chopsticks.

3: The urge to pull out
After cutting, many growers are eager to know when the cuttings will root, and they can't help but check them every day. If you do this, congratulations, your rose cuttings will never root again.
The process of rose cuttings rooting is very fragile. Any movement of the cuttings will affect the healing tissue and rooting of the roses. Therefore, during the rose cutting period, don't pull them out.
The time for rose cuttings to root is usually between 1 to 4 weeks. It is recommended to gently pull the branches after 4 weeks to see if there is resistance. If there is resistance, it means that they have rooted. Before that, don't touch them.
4: Don't be happy about false vitality
The situation of false vitality usually occurs in winter. Although Mu Mu mentioned earlier that the best time for cutting is after spring and autumn flowering, if the temperature is around 10° in winter, it is the season with the highest rooting rate for beginners, even though the rooting time is slower.
However, cutting in winter also has a very troublesome problem, which is that if the temperature is slightly higher during a warm winter, the branches will sprout提前. Don't think that the branches sprouting means that the cutting has succeeded.
This sprouting is just due to a sudden increase in temperature, and the roses rely on the nutrients stored in the branches to sprout. These tender new buds usually start to wither and wilt within a week, and once this happens, there is no chance for rooting.
If you encounter false vitality during winter cutting, there is basically no way to stop it. We can try to avoid cutting in winter, and if you have to, do not cover the cuttings with plastic film to warm them up. Also, if you encounter a brief warm winter, try to move them to a shaded area.
5: Blackening of branches is most common
During the rose cutting process, the most feared thing is blackening of the branches, which means the cutting has completely failed. So, what exactly causes the cutting branches to blacken? Mu Mu will analyze this for you below.
