I have this area by my house that would be perfect for adding on to my big garden. The problem is, the owners before me threw concrete into the bed and wood chips. Last year I got the sumac trees out of it. And also got all the weeds out of it. But before I could get anything planted in it, weeds just continued to grow and grow, in which I couldn't keep up with it. Should I just forget about it or tackle it? And if so, what are some of your ideas.
