I'm not sure this is the correct place to ask this question but here goes. We just moved to central Maine and we brought all of our trees from our other home with us...34 in all … lilacs, evergreens, pines and holly...obviously they are all fairly small still. Is it safe to put them in the ground if we build small teepee's over them and wrap them with burlap? We will have snow here by November but the ground won't really freeze until December. Any help would be appreciated. thanks!
