I am buying a new house and will close here in the next week or two. Behind the house my property goes down ot a creek. There is about a 50 yard x 20 yd area that has not been mowed or cut back for at least 3 years. There are many saplings and heavy vegitation. Should I Round Up (creek?) or weedwack then chain saw? There is a chain link fence overgrown in the area too. I am looking for an easy way since this is my property and I have lots of customers to take care of this year.
