I used to use a lot of compost when I could still use a shovel!
But now that I don't make new beds, or plant many things, I don't use much. I have four big bins made over the old Victory Garden plans. They worked well when I had huge beds, and was adding lots of stuff. Now, I add to it, but have not used much of it. Two years ago, when we made that new bed in front that I showed photos of, we emptied it all out. Probably had six years worth of stuff! It was great!
