We would like to repair and maintain two parkways which have gone to weed for many, many years. Our thought is to begin now when nothing has yet grown, but we need a plan. How can we best get rid of those deep-rooted weeds in an environmentally safe and economically prudent way? What kinds of low maintenance alternatives are there to beautify those parkways and keep them weed-free? We are not experienced gardeners so any information you can pass on to us would be most helpful. Thank you.
