If you are having discussions with your clients about doing roundup and re seeding on their own make sure they are not using one of the extended control roundups. Got into this today with a conversation about tall fescue and quack grass etc. I never thought of it before but the last few years they are selling roundup with surflan or I don't know what they are using. Prodiamine maybe. Anyhow just tossin this out there. Oh I guess this goes for the homeowner lurkers too and the less than licensed rookies.
