I am moving my bucks into a new 2 acre pasture. It has many young pine trees as well as some large pines. It has been select cut and the stumps removed to prepare it as a pasture. How can I keep the small pines from getting eaten and destroyed? Is there an application that will repel them? It is quite a few to be fencing around. They are between 8' and 20' tall. I really need to save them! Any suggestions, please?
