Heya, very new to all this. My husband and I decided to build a hugelkultur. Before doing adequate research, we built a rather extensive base of fairly green/freshly cut logs all over our medium small suburban backyard. I am looking for advice to make this work-- I've learned that typically people suggest using logs that have already been decomposing for a while. It is spring now, and it's not important to us that we are able to plant on it this year (although of course that would be fun). But how do we fill it in, so that it works next year? And do we need to dig the logs into the ground-- what exactly is the benefit of this?-- I guess it provides you with soil to fill in the gaps? Any advice for acquiring large amounts of soil for cheap?
Thank you
