Just picked up a very large HOA common ground area, bermuda with some areas much heavier with weeds (clover, oxalis, of course some crabgrass) than others. Turf is fair to pretty good. I'd rather wait until fall to attack the weeds, but I feel I've got to clear out some of those areas to encourage bermuda growth. Got to still get a soil test, but I would like to a good core aeration ASAP. What's the theories about aeration and the spread of weeds in those areas that are pretty heavily infested? Also, I haven't had much experience w/bermuda....what is the best solutions to encourge it to spread?
