How to preserve tree stumps for bonsai against rot? These practical methods are a must-know
A fine bonsai work can only be completed after 5-8 years of careful management, but during the care process, how to prevent dead branches from continuing to rot is the most worrying thing.
The most common way to preserve tree stumps against rot is to coat them with lime-sulfur mixture (a mixture of lime and sulfur).
The preparation method of lime-sulfur mixture: one part quicklime powder, 2 parts sulfur powder, 10 parts water, boiled and prepared. One point to emphasize is boiling! That is, boil it in a pot and then use it, because sulfur powder generally does not dissolve in water. Tree stumps can be treated during both the growing season and the dormant season; in winter it is mainly for prevention, and the effect is very good. Also: lime is alkaline, sulfur powder can improve soil acidity, and both have the effect of sterilizing and preventing borers.
