Due to the crazy spring weather (rain and heat) my st. Augustine weakened (we think we had chinch bugs too) and has been taken over by what I call \"crazy grass\" that is actually a weed -- we\'re going to get new sod but I don\'t know how to kill this stuff without endangering my new sod. Also, I want to know if I can put kraft paper under the new soil prep before the sod is laid as a weed barrier. This is so bad. :(

Here is the pic of the weed -- I was told it has a white flower at some point. The sod guy said he didn\'t recommend a weed killer as it may kill the new grass as well.
