Wow. That looks so good. Right now I have several layer of card board. Plan to add about 30 cubic feet of composted cow manure. Then 15 cubic feet of top soil then mulch on top before I plant. I'll have to think about the straw top. I think I'll need it as well.
Sounds like a good plan. I have never seen a keyhole garden that large.
I put the cow manure, finely chopped wood chips, and leaves in the compost pile and after a year add them to the keyhole garden. I also add some cottonseed meal to heat up the compost. Do not add un-composted cottonseed meal to the garden or the coons will be attracted to the smell and start digging.
