Bonsai trunk rot is a common problem that can affect any type of bonsai tree. The causes of this condition are numerous and can vary from one tree to the next.
However, there are some general solutions that can help to treat and prevent trunk rot in most cases.
There are many factors that can contribute to the development of bonsai trunk rot.
Some of the most common causes include: over-watering, under-watering, poor drainage, soil compaction, inadequate air circulation, and insect damage or fungal infection.
In addition, exposure to direct sunlight or wind can also lead to drying out and cracking of the bark, which makes the tree more susceptible to rot.
The symptoms of bonsai trunk rot can vary depending on the severity of the infection and the specific cause involved.
Generally speaking, you will see a gradual decline in the health of the tree accompanied by wilting foliage, dieback, and stunted growth.
The bark may also start to peel away from the trunk or branches and you may see evidence of fungus or decay inside the wood. If the rot has progressed to a more advanced stage, the tree may collapse entirely.
If you suspect that your bonsai tree has trunk rot, it is important to take action immediately in order to save the tree.
The first step is to correct any cultural problems that may be contributing to the condition.
This means ensuring that the tree is receiving the proper amount of water and drainage, adequate air circulation, and the right type of soil.
It is also important to remove any dead or dying branches from the tree as these can provide a entry point for decay-causing organisms.
In some cases, you may need to disinfect the tree with a fungicide or bactericide in order to kill any pathogens that are present.
Once the tree is healthy again, you can then focus on preventing trunk rot from occurring in the future.
This means following a proper care regimen and being vigilant for any signs of stress or disease.
If you catch the problem early, you can often save the tree with little to no lasting damage.
Bonsai trunk rot is a serious condition that can quickly kill your tree if left untreated.
However, by taking action quickly and correcting any cultural problems, you can often save the tree and prevent this condition from occurring again in the future.

What to do if you suspect your bonsai tree has rot
Bonsai tree rot is a common problem that can affect any type of bonsai tree. The good news is that there are steps you can take to prevent rot and, if it does occur, to treat it and save your tree.
In this section, we will discuss what causes bonsai trunk rot, how to identify it, and the best ways to treat it.
Bonsai trunk rot is caused by a variety of fungal diseases that attack the wood of the tree.
The most common type of fungus that causes rot is Phytophthora, but other fungi, such as Armillaria and Ganoderma, can also be to blame.
These fungi thrive in moist conditions and enter the tree through wounds in the bark. Once they are established, they begin to break down the woody tissue of the tree, causing the trunk to rot from the inside out.
There are several signs that you can look for to determine if your bonsai tree has trunk rot. If you see any of these signs, it is important to take action immediately.
The first and most obvious sign of trunk rot is discoloration of the bark. The bark may turn brown or black and begin to fall off in patches.
Another sign of trunk rot is softening or punky wood. If you can poke your finger through the bark and into the wood beneath, this is a sure sign that the tree has rot.
Mushrooms growing at the base of the tree or on the trunk are another tell-tale sign of trunk rot.
Finally, if your tree suddenly begins to lose its leaves or they turn yellow and drop off, this could be a sign that the tree is dying as a result of trunk rot.
If you suspect that your bonsai tree has trunk rot, the first thing you should do is isolate the tree from your other plants. This will help to prevent the spread of the disease.
Next, remove any affected branches and dispose of them. It is also a good idea to sterilize your pruning tools after each cut to avoid spreading the disease.
Once you have removed all of the affected tissue, it is important to treat the wound with a fungicide. This will help to prevent the fungus from returning and will also promote healing.
There are a number of different fungicides available on the market, so be sure to choose one that is specifically designed for use on bonsai trees.
Follow the instructions on the label carefully and apply the fungicide according to the directions.
Be sure to treat any other wounds on the tree, even if they don’t appear to be affected by rot. This will help to prevent the disease from spreading.
Once you have treated the wound, it is important to monitor the tree closely. Check for new signs of rot and take immediate action if you see any.
With proper care and treatment, most trees will recover from trunk rot. However, it is important to remember that once a tree has been affected by this disease, it will always be susceptible to re-infection.
