I am planting new garden beds, fruittrees, and even a mini-hugel on my suburban lot. I have to bring in compost this year (hopefully I will make enough of my own in the future). I need about 4 cu. yds. and must get it from a local landscaping nursery. They sellmushroomcompost and leaf compost.
I am no-tilling and planning it just put three inches of compost over top the cardboard, soil, straw layers I already have.
Should I get the mushroom or the leaf?
And if I get the mushroom, should I mix it with soil (50/50) first?
Which is cheapest? With all the different materials you are using to construct the bed, I don't think you are going to have a lack of any specific nutrient, so the question then just reduces to which is more economical?
