There are things in the greenhouse! There were a lot of steps to get to this point (and a lot of photos below) but here are the highlights. If that seems boring though, just scroll down to the bottom for a little chicken TV entertainment instead.
The greenhouse is situated in what was once a horse arena, so the ground below is compacted, gravelly and weedy. We're using no dig practices to combat this less-than-ideal foundation, starting with a temporary layering of black tarps to smother the grass and weeds early in the season before they could grow. Next we ordered custom cut cedar planks -- they smelled so good -- and treated them with a special eco-treatment that's safe for plants.
We built looooong beds and stapled 1/2-inch grid wire (hardware cloth) to the bottoms to thwart the pocket gophers. Next we placed a layer of straw bedding from the winter chicken run in the bottom of each bed. This layer is a weed barrier initially but will eventually break down to add organics to the soil.
That's our tractor trailer -- cute eh? Next we loaded soil into the beds one at a time as they were built, allowing us to use the tractor to fill all but the last one. The last one we did with a wheelbarrow -- 42 loads worth.
Finally a load of well-rotted manure topped each one. We laid landscape fabric in the walkways, topped that with wood chips, and then set up a drip irrigation system.
