No weeds found today so it must work well!
Only moss found in back "lawn" area where water sits because of builder failing to slope yard properly, so a rented back hoe, bobcat or something will fix it after I get it marked out. Certainly not doing that job by hand. The little that was in new iris area last season is all dried up; I had hoed it up and just left it on top of the soil and put down a light application of ground limestone.
