Hello to all. I am getting ready to start cleaning out the rotten wood, and getting the deadwood treated on an azalea. The inside of the main trunk had some areas that needed cleaning off before putting the sulfur on. I used a sandpaper wheel on a dremel tool, and cleaned it out. As i was getting started, i noticed a spot where i could see green from the living tree. Should i put cut paste on this to protect it, or is it ok to put the lime sulfur onto it? I know you dont get the sulfur on living areas, so i want to make sure before proceeding. Ive put up a couple pics, not sure if you can see it though. There is a branch covering up part of where im talking about. You can see the white areas near the top of the old trunk. What do you think about my new find?
