|Layers of wheat straw, cardboard, more straw, and a few inches of mulch on top of grass and weeds.|
For a few weeks my strategy involved spreading wheat straw all over the portions of grass I wanted to smother. I followed that up with layers of thick cardboard. I made sure to provide significant overlap from piece to piece to avoid gaps in the coverage. Then I added another layer of straw and finally a thick 3-4" layer of fresh mulch.

I plan on using the same type of untreated 2x8's to enclose the un-mulched sections for planting. I'll likely plant the new spaces with tomatoes since I planted the majority of beds with tomatoes last summer. This will provide me with some additional rotation space and will prevent the buildup of pests and diseases in last year's locations.

I'm gambling on the idea that layer upon layer of mulch will smother the grass and weeds. The concept is also quite similar to lasagna gardening. I have no doubt that grass and other things will conspire against me and grow, but I'm hoping for the best. In the photo above, I still need to mulch the area between the covered beds and white fence, the area in the back right adjacent to the shed, and the area behind and to the left of where I was standing when I took this photo. I will post more about my plans for the area near the white fence at a later date this winter or early spring. Think fig trees...
