I'm going to become a volunteer groundskeeper for a local neighborhood pool we belong to. One of the main areas that is like to focus on and need advice with is this area near the driveway. It looks like once upon a time it has some roses and shubs. I'm looking for support with ideas and tips that are inexpensive. I have the time and the willingness to do work, but not much experience or free money. Can I bring the roses back from the brink of despair? How best does one manage those shrubs? Could they look better with a trim? Oh and that sweet gum tree.... Thanks!
