Been thinking about it for over a year, have plenty of both white and brown bark paint used on citrus. Well don't wait like I did, it was very obvious by the third day that the newly painted stems had a huge effect on growth, every plant perked up and they were looking pretty good already. Would like to hear what others have experienced.
Edit: To be a bit more clear I am referring to stems or branches that are exposed to hot noon time sun, thus the reference to bark paint.
