How to deal with the blind branches and buds of Chinese roses?
For most women, the topic of dealing with blind branches and buds of Chinese roses is related to flower cultivation. Let's follow the editor to see the specific content!
Recently, many friends have encountered the problem of all the buds of the Chinese rose turning into blind branches after germination. Generally, we handle the blind branches of Chinese roses by pruning or breaking them off. So, if a new branch of Chinese rose is all blind buds, should we break off the blind buds to let the rose grow again? Before making a decision, it is still necessary to understand the causes of the blind buds of Chinese roses.
Causes of blind buds in Chinese roses
There are generally two main reasons for blind buds in Chinese roses:
1. Insufficient fertilization and watering can lead to weak growth of some branches, resulting in blind branches that cannot bloom. 2. Insufficient lighting causes blind branches in Chinese roses, especially the buds near the base and inside of the plant, as they are blocked by the upper branches and leaves, leading to severe lack of sunlight and poor growth, eventually turning into blind branches.
However, the above two reasons usually only cause some branches of Chinese roses to be blind, while the other branches can grow and bloom normally. In these two cases, we can handle the blind branches by breaking them off or pruning.
But if a new branch of Chinese rose is all blind, we can no longer use the above methods to handle it.
Causes and treatment methods of blind branches in the whole plant of Chinese roses
In spring, if the fertilization and watering of Chinese roses are in place, but the whole plant still has blind branches, the first thing to consider is whether there is a problem with the roots.
For example, if the roots of Chinese roses come into direct contact with fertilizer during potting in winter, it can cause root burn. It may not show any abnormalities in winter, but in spring, after germination, the new buds will wither or grow poorly, resulting in blind buds. The reason behind this is root damage.
If our Chinese roses are new propagation seedlings, such as those obtained through high-air layering, the roots may not be well-developed, but there are many branches and new buds, and in such cases, Chinese roses can also have all blind branches.
Some grafted seedlings may also have very little nutrient intake due to aging of the rootstock, poor nutrient transport, or partial shedding or black rot at the grafting site, resulting in the phenomenon of all blind new buds in Chinese roses.
For Chinese roses with all blind buds, do not remove all the blind branches. Instead, remove some blind branches from dense leaf areas to enhance ventilation and retain most of the blind branches to allow leaves to photosynthesize and produce nutrients.
Chinese roses with all blind new buds are relatively weak. If we remove all the blind branches, the Chinese roses will become bare stems without leaves for photosynthesis. Even if new buds are produced, they will still be very weak and likely turn into blind branches, which cannot be changed by frequent fertilization.
Therefore, for Chinese roses with all blind branches, it is first necessary to identify the cause, whether it is due to root problems, aging of the grafted rootstock, or poor nutrition due to branch damage.
If the whole plant is blind due to poor roots, then speed up the drying and wetting cycle of the potting soil, keep the potting soil slightly dry, add a little root stimulant when watering, and promote rapid root growth in Chinese roses. Once the roots are healthy, the Chinese roses will naturally grow new branches and bloom.
If the Chinese roses are grafted seedlings and the rootstock is aging or the grafting site is damaged, it is difficult to cultivate them well. The first step is to supplement nutrients through foliar application to allow the branches of the Chinese roses to grow first, and then consider layering or cutting for backup, as the nutrients provided by the rootstock for the Chinese rose buds are too limited and abandonment may be considered.
Although grafted seedlings of Chinese roses grow quickly in the early stages, they are indeed more prone to problems. This is also the reason why the book "How to Raise Chinese Roses from Scratch" strongly recommends choosing cutting seedlings.
The above experience and knowledge about dealing with blind branches and buds in Chinese roses, I hope this article can provide you with some help!
