Crabgrass Preventative
Last season I had a huge problem with crabgrass in and around my display yard. What is the best preventative, rate and time of application? I am reading about a new OHP product Marengo, with some interest.

That looks to be a great choice. I know Surflan is another popular choice but the orange residue might be unattractive.

Holy Cow, I looked into the price of Marengo, and it's over $1000 for a half gallon. Needless to say, we won't be using that!!

Kathleen, For $1,000 you could buy a pretty decent flame thrower! :)

You can try corn gluten. It comes as a granule that you spread around. It inhibits root growth of the crabgrass seedlings so the timing of the application is important. It has about a 4 week control time. We sell it in our garden center for homeowners who wish to have an organic control of crabgrass in their lawn.
