Making new dirt- should I layer it as compost, cardboard, then wood chips or should I put the cardboard on the bottom?
I have a 1400 sq ft yard that I want to completely cover with a combination of cardboard, compost and wood chip mulch. My original plan was to put the compost on the bottom, then cardboard on top, then wood chips on top of that, but then I thought that the cardboard may not break down as fast as I would like in order for me to plant native grass and wildflower seeds next spring. I’m planning on putting down a half inch of both the compost and the wood chips.
I know it may be a little overkill to do all of those layers to suppress the seeds already present in the dirt, but I want to be thorough. Thanks in advance!
Edit: I forgot to add, but it’s pretty loose dirt that I will be covering- not a lot of structure/health to it, and not dark at all. I am in zone 7a, New Mexico high desert
