A comprehensive introduction to the experience of plant care regarding what to do if the black stem appears on the cuttings of Chinese roses. Next, the editor will introduce to everyone.
What to do if the black stem appears on the cuttings of Chinese roses
Previously, I shared the method of transplanting Chinese roses after they have survived from cuttings. Then, some flower enthusiasts left comments, saying that they have never succeeded in propagating cuttings, always ending up with black stems, or the new buds withering after they grow. So, how exactly should cuttings be done? Today, I will briefly introduce the propagation method of Chinese rose cuttings.
Why do some people succeed in propagation even with casual cuttings, while others, despite sterilizing and soaking in root growth powder, still end up with black stems? In fact, many times, it's not that our own cutting methods are problematic; home propagation is very dependent on the right timing, location, and conditions.
What is the right timing?
The right timing refers to the time for cutting Chinese roses, or the climate environment. In regions with a good climate, where it's like spring all year round, the survival rate of Chinese rose cuttings is very high. But most of us are not living in such regions, so we need to choose the right time for cutting.
The best time for cutting Chinese roses is early spring and autumn. The characteristics of these two seasons are relatively low temperatures, slow bacteria reproduction, and relatively slow water evaporation, which are more suitable for the cuttings to grow roots.
The difference is that Chinese roses cut in early spring quickly enter the hot summer after surviving, facing the challenges of summer heat and diseases and pests. Chinese roses cut in autumn, after surviving, quickly enter dormancy, which is relatively more beneficial for root growth, and the growth in the following spring will also be more vigorous.
Moreover, Chinese roses cut in early spring and autumn can be transplanted into pots immediately after surviving, which makes management much easier.
What is the right location?
What is meant by the right location is where the cuttings are placed after propagation. Many flower enthusiasts always end up with black stems in their Chinese rose cuttings, and one of the main reasons is rain. Especially for Chinese roses cut in May and June, the temperature is relatively high, bacteria reproduction is fast, and it's the rainy season. If the cuttings are placed in a location where they get rained on, it's easy for a large area of the cutting stems to turn black, often resulting in total loss.
Besides cutting in winter, early spring, and late autumn, when you can directly expose the cuttings to sunlight and rain, green plant enthusiasts are advised to avoid rain in other seasons, placing them in a bright area with diffused light to wait for root growth, which leads to a higher survival rate.
What is the right condition?
The right condition is really our propagation process, including the selection of branches, pruning of cuttings, substrate, and sterilization operations.
