I got some compost from my mom’s compost pile. That is what is in the garbage bags. I got the framing from the rugby pitch. It is an old dock that floated down to Indianola during a flood a few years back. The decking is made out of recycled plastic and is pretty sturdy. It should last a lot longer than wood would. (ha). So, there you have it. Compost + some stuff that floated into a rural valley during a massive flood = garden.
I dug up the grass that was there, turned it over, and added the compost and some store-bought bags of soil. Should I have tossed the sod? Probably. Oh well.
