This article introduces the small knowledge of dealing with black stems in rose cutting. Next, the site editor will introduce to the netizens.
As it happens, there is a solution for dealing with black stems in rose cutting.
Previously, I shared the method of rose cutting, and many flower friends have tried rose cutting. In the process of practice, we often find that the actual operation is not as simple as it sounds.
In the process of rose cutting, we often encounter two situations:
1. Rose branches turn black
In high temperatures, the survival rate of cuttings will decrease significantly because high temperatures accelerate the reproduction of pathogens, making rose cuttings susceptible to pathogen invasion and resulting in black rot.
Solution: When cutting roses in high temperatures, it is important to sterilize and disinfect. Rose cuttings should be soaked in carbendazim solution or soaked in potassium permanganate solution for disinfection.
The potting soil for cutting should be plain soil without fertilizer, and the soil should also be disinfected. It can be watered with carbendazim solution or potassium permanganate solution for disinfection.
During the cutting process, watering with carbendazim solution can also help disinfect and kill germs, reducing the probability of black stems.
2. Rose sprouts but soon withers
How to deal with black stems in rose cutting?
Sometimes, a week after cutting, the branches of roses will sprout, and many flower friends are happy to see the roses sprouting, thinking they have survived. However, a few days later, the new sprouts of the roses wither. Why is that?
This phenomenon is called "false revival" in roses.
The false revival phenomenon in roses is related to the variety of roses and also to temperature.
Generally speaking, if the temperature of the soil is higher than that of the air, the cuttings of roses are more likely to grow roots. Conversely, if the air temperature is higher than the potting soil temperature, the rose branches are more likely to sprout first.
The growth of new rose sprouts quickly consumes the nutrients in the rose branches, causing the nutrients to be used up by the new sprouts before the branches have grown roots, eventually leading to black rot.
Therefore, when cutting, it is important to maintain the temperature of the potting soil and not let the air temperature get too high. Also, pay attention to sterilization and disinfection to prevent pathogen invasion.
Rose cutting is actually very simple; you just need to try more and not get discouraged. With more attempts, you can find the right technique for your own cuttings.
