What to Do If Bougainvillea Drops Leaves After Transplanting? Causes and Solutions

We all know that bougainvillea, from propagation by cuttings to growing into a potted mature plant with a certain ornamental value, needs to go through the process of transplanting. Transplanting is done so that it can grow in a better environment, and whether the transplanting method is scientific and reasonable will directly affect the survival and growth state of the plant. In the previous article, the editor told everyone "How to Transplant Bougainvillea," but if the transplanting method is improper, it may cause a series of problems, ranging from affecting the growth state of the young plant to possibly causing death.

The problem most likely to occur after bougainvillea is transplanted is the wilting and dropping of leaves. Of course, compared with wilting, the dropping of leaves is a more serious phenomenon. In the article "What to Do If the Leaves of the Radermachera Sinica Wilt After Repotting" published a few days ago, the editor analyzed for everyone the wilting phenomenon that appears after transplanting the Radermachera Sinica and its countermeasures. In fact, bougainvillea is similar, and everyone can refer to it. So, what should be done if bougainvillea drops leaves after transplanting? We first need to analyze the causes.

Because it is transplanting into a pot, and before the young bougainvillea plant is transplanted into a pot, it also needs pruning of branches and roots. This is mainly to save unnecessary nutrient consumption for the young plant, allow nutrients to be transported in a concentrated way to the retained branches and leaves, and thereby improve the survival rate of transplanting. But pruning must be moderate. If the pruning is too severe, whether it is pruning of branches and leaves or pruning of the root system, this is very unfavorable to the survival of the plant.

The phenomenon of bougainvillea dropping leaves after transplanting is generally caused by excessive pruning. In particular, pruning of the root system is too harsh, seriously affecting the young plant's normal absorption of water and nutrients. Because the damage is severe, water and nutrients cannot be used in time by all parts of the plant body. When the branches and leaves cannot get supplies, if this goes on for a long time, leaf drop will naturally occur.

Of course, there is another situation, namely that the degree of pruning is relatively appropriate and the potting process is also correct. Then why does bougainvillea still drop leaves after transplanting? In fact, the problem may still lie in the root system. Although the root pruning method is correct, if the roots are not sterilized and disinfected after pruning and the potting soil carries quite a few pathogens, then the pathogens will invade and infect the wounds from the root system. If we still ignore it and continue potting, the infected wounds on the root system will become larger and larger, and may even cause healthy roots to rot as well. Since the root system of the bougainvillea is already damaged, it is unavoidable that leaves will drop after potting.

Even if neither of the above two situations occurs, we may still encounter the phenomenon of bougainvillea dropping leaves after transplanting. This is the third situation the editor wants to mention - the root system and the potting soil are not combined closely enough. We said before that before the young bougainvillea plant is potted, in addition to root pruning, it also needs to have its roots soaked in red soil slurry. The purpose is to make the root system contact the soil more closely and make it easier for the root system to absorb nutrients and water from the soil.

Perhaps it is precisely because when transplanting the young bougainvillea plant, the root system was not soaked in red soil slurry, and the potting soil and the plant were not in close enough contact, so the plant's root system cannot normally absorb nutrients and water from the soil, and therefore the phenomenon of leaf drop occurs. So, as the editor said in the previous article, during the transplanting process, bougainvillea needs to have its root system soaked in red soil slurry.

Bougainvillea dropping leaves after transplanting is mainly caused by problems with the root system, so to identify the crux of the problem, we first need to investigate from the root system and then take corresponding handling measures.

First, we need to check the condition of the root system, whether it is excessive root pruning, or infection of the root system by pathogens leading to rot, or whether it is in close enough contact with the potting soil. Only after finding the real cause can we take timely countermeasures. If the root damage is relatively light, we need to cut off the rotten parts of the root system, then carry out disinfection and sterilization treatment, and afterward replant; if the root system and the potting soil are not in sufficient contact, then we need to fill the gaps between them with soil, and then gently compact the potting soil around the plant. In short, analyze specific problems specifically, and when using rescue methods, adapt measures to local conditions.
