Suggestions for creating good soil?
I am going to begin the process of digging out all the garden beds surrounding my house to replace approx 12" of back fill (containing at least 1/3 rocks) with something better suited for perennials. I have only found info on suitable homemade mixes for raised beds - not foundation beds. Would a 50% clay, 50% compost mixture be overkill here? Has anyone started their beds from scratch? What did you use?
Many thanks for any advice!
