Yeah, I found that the hardest part with my compost bin was to accumulate enough green and brown material to fill it to the top and leave it to compost....I kind of ended up throwing random scraps and brown leaves in there along the way.

I'm a bit jealous about all of your autumn leaves! Where we are we don't really get a real 'autumn', so I usually prune shrubs/trees and pile them up to die/brown off.

I was surprised at how rich and healthy the compost turned out, it was nice to see the 'black gold' all things considered - always room for improvement though :-)
