Hello everyone! I'm the new guy on Lawnsite. Been lurking for a while and gleaning some good info as well as some good laughs (it's nice to know I'm not the only one with customer horror stories). Anyway, I finally decided to try a post. So, here goes: Does cutting a lawn low help get rid of weeds? Does cutting a lawn high help bare spots under trees to fill in? If the answer is "yes" on both of these questions, should I just cut it high and tell the lady she'll have to have it sprayed for weeds? Thanks for your help.
