I have worked very diligently to take care of my beaver problem. As far as I know, as of last month, i have no more beaver problem. After posting in this thread, I went and reevaluated my trees. They haven't tolerated my winter very well. I am fearful that I didnt water them enough during the winter months. I wasnt very good about checking then during the winter. I didnt water for a while... They have some green left, but have some brown as well. I hope they perk up in the spring, otherwise, i will have to try round two...... i hope not! it is getting expensive to build a living fence!
