Yeah, you can tell that hostage bed is loving the extra nitrogen. It's beautiful!
The grounds from my coffee pot get mixed in with the kitchen scraps. I have a bucket out the back door for all of that stuff. The grounds from the coffee shop go on top of my hugelkulture bed. My two bins are full of shredded leaves/grass and more grounds.
It is my first time trying hugelkulture, so I'm excited to see the results!
