Dang that's a lot of compost, am jealous, we try not to buy some, but our soil is very alkaline so there's little choice.
We have a relatively small box (compared to the size of the garden), but that's also coz we leave the grass clippings over the grass itself so as to not dry out the soil underneath too much.
But everything from kitchen scraps to hair clippings and wood shavings are in the Compost now โป๏ธ
