I wanted to share a technique that I learned from a You Tube video produced by The Bonsai Supply Co.
It's an easy way to address sunburn or surface damage left from a broken branch using Limestone Powder
In the past when I wanted to seal a damaged area I used wood glue. It works, but the glue remains forever leaving an ugly site.
This is an adenium that arrived with caudex damage in June of 2019 that I treated with wood glue.
Alive, but not very pretty!
