too early for Preen?
 

My once beautiful fescue lawn is now covered in weeds. I don't
aspire for it to be the perfect lawn it once was but I would like
to have it look decent. Is it too early to spread Preen? Should
I reseed the bare(r) spots afterwards? Is aerating really
necessary? Ugh. This is not the way I want to spend my time and
$$ but a certain amount is a necessary evil.
Thanks for the advice!
