I don't think we will be digging a big hole to compost in. The ground here is like concrete and I am sure I could build six compost bins in the time it would take me to dig a hole that big.
We have a compost bin we started using last year. I am curious to see what we have come spring this year.
Just digging up my new vegetable garden took all the energy I could come up with and it was only a few inches deep, we built it up with top soil and peatmoss. We will try to dig it a bit deeper this coming spring when I double the size of our garden.
