Common blind buds in roses and their treatment methods
An explanation for netizens who are concerned about the causes of blind buds in roses, knowledge about green plants and flowers, let's learn about it together below.
Previously, I mentioned the reason why roses tend to have yellow leaves during this period, including the issue of breaking off blind buds. In fact, blind buds in roses are a very common phenomenon, but not all blind buds can be broken off. So, what kind of blind buds can be broken off, and what kind cannot? Let's talk about this issue in detail today.
One, the causes of blind buds in roses
The fundamental reason why roses develop blind buds is insufficient nutrients, and there are many reasons for insufficient nutrients, such as insufficient light, untimely fertilization, insufficient fertilization amount, and absorption障碍 in the rose root system. Even if a lot of top dressing is applied, only a little is absorbed, which can lead to the phenomenon of blind buds in roses.
The weaker the branches, the more likely they are to develop blind buds, because they are inherently weak and compete with strong branches for nutrients, they are certainly at a disadvantage. Therefore, most old weak branches, if not pruned in winter, will become a large number of blind branches in spring and bloom very few flowers.
In addition to weak branches being prone to blind branches that do not bloom, buds in the center of the plant and those near the bottom, if not strong enough after germination, are also very likely to become blind branches because the upper new branches can easily block the sunlight. Due to long-term lack of sufficient sunlight, they will become weaker and weaker, not only causing blind buds but also easily leading to yellow leaves.
Two, common blind buds in roses and their treatment methods
Common blind buds in roses and their treatment methods
Based on different causes of blind branches, their manifestations will also be significantly different, and the treatment methods are also different.
1. -- Blind branches with a cluster of leaves inside --
Weak buds inside the plant, due to insufficient sunlight and their own weak growth, often result in a cluster of leaves after germination, without any branches. Most new buds on weak branches are also this type of blind bud.
The treatment method for this type of blind bud inside the plant with a cluster of leaves is to break them off directly to avoid affecting the ventilation inside the rose plant and increasing the probability of infection with red spiders and black spot disease.
But note that if our rose plant itself is weak and the new buds look like a large cluster of leaves and are at the top of the branches where they can receive sufficient sunlight, this indicates that the root system of the rose is not very healthy or there is a severe nutrient deficiency. In this case, it is not suitable to break off the blind buds directly, but rather to retain these blind buds to photosynthesize and produce nutrients.
2. -- Blind branches near the base of the plant --
In spring, roses also tend to sprout new buds from near the base, but these new buds will eventually take different paths due to differences in growth. Those with vigorous growth will become strong suckers, while those with weak growth will often stop growing after a section of branches has grown, resulting in yellow leaves and becoming blind branches.
3. -- Blind branches on the outside of the plant --
Some branches originally grew well and are thick, but they develop blind buds without forming flower buds, which is due to insufficient fertilizer and water.
