The well-intended services are good, the operators move about quickly, and the healthy grass does well. However, as of today's date we have mostly the large quack-grass (name unknown) covering a large part of the yard. A lawn service tends to the cutting very well, so I have no idea of how this much-disliked intruder grass has taken over. Any response on this will be appreciated. In the past I have sent at least one customer to you - and will consider more if available. Hopefully you can do something regarding this unwanted condition. Thanks.
