I am on a mission to thin out the gum trees on my land and admit I know little about tree control. How would you go about this? These are smaller trees. Last fall I experimented with skinning the bark with a machete and applying gly which was successful but a slow process since I have hundreds. I've just read on basal bark application where you soak the bottom 15" of bark which would go much faster. It seems triclopyr is the commonly used chem. From what I'm told fall is the best time to do this since trees are taking in carbs for winter. Any tips on basal bark apps appreciated, at what concentration would you use the triclopyr?
