I have a customer that wants me to do something to get her lawn looking better. The lawn is very patchy and is still showing bare spots from where the irrigation was installed. It's fescue and I hate doing any kind of fescue seeding this time of year for obvious reasons but, she wants it done. I know I can aerate and overseed but, was wondering your thoughts on using a turf reviltilizer this time of year? I havent ever used one and this may be my opportunity. Thanks for any help.
