My husband was trying to remove the moss and weeds from our front lawn with a product called RoundUp. It is heavily shaded most of the day, with drainage problems too. He had tried lime earlier in the spring with no noticeable results. Unfortunately he tends to believe 'more is better' and our lawn has been a messy patchwork of burned brown spots, patches of dandelions and moss (yep, THEY survived) and tufts or green grass since late last summer, after the spraying with Roundup How do we repair and/or replace this mess at minimal cost? We are both middle-aged and disabled so are not too keen on redoing the whole lawn. I was wondering about aerating then adding sand for the moisture problem, then just reseeding the entire lawn. Any help for these neophytes greatly appreciated.
