Same here, Gina.
Lee-Roy, I'm not surprised the grass is growing through the mulch. If it was that easy, everybody would just do that. If you had put cardboard under the wood chips. the grass would not be able to get through. Lack of rain is not an issue here for most of the year, except summer sometimes but I wouldn't be working on a smother in the heat anyway. If you're looking for something you can use right away, smothering is not the path. I usually leave it alone over winter. Time is a requirement of smothering. After the cardboard decomposes, it is no longer a barrier. Trying to use a smothered area before the cardboard decomposes defeats the purpose, IMVHO/E.
