Dog fennel is one of my favorite plants.......It makes the best screening of anything I've seen. As a matter of fact, my screens and buffers from last year are still standing now while the new ones are growing....A nice mix of dog fennel in a summer stand allows you the ability to go in and "carve out" a plot of whatever shape you want it to be with whatever types of visual screens and dividers you might want to include into it......Let's say you want to take a larger plot and divide in half or quarters or you wanted to leave a perimeter buffer all the way around it. For example, in the pic above my bigger field is actually on the backside of that dog fennel screen......The strip I'm showing in the pic is the lane where the buck makes his mistake when the does disappear into the field........
