I have a juniper procumbens with shari that extends down to the base of the trunk. There is a space at the bottom that collects water every time the tree is watered and has a fair amount of moss growth. I am concerned that this may eat away at the deadwood over time.
I was thinking of using lime sulfur to protect the deadwod, but in order to get it deep into the crevice, it will sit against the surrounding healthy wood. Is that okay?
I have also tried scraping away the moss with a brass brush, but the brush is not fine enough to reach deep into the crevice.
Any other suggestions on how to protect this region?
