When do you need to brushog your pasture? It depends on what you are trying to accomplish. Sometimes the brush tries to take over certain parts of your pasture. Mowing it off sets back the brush into a more vegetative state that allows animals to eat the regrowth. This is much better than letting the brush take your farm. Some landowners like the appearance of a "kept" pasture, mowed off at least once per year. If you want to keep your farm profitable every year, check out my 3 grazing books that I wrote on our website: http://greenpasturesfarm.net/books/
