Converting a bed to "mel's mix"
I've got 7 raised beds (totaling ~900 sq/ft of surface area) that are largely just leaf compost. I've been working in some quality compost as I can and have worked in a little bit of peat moss and vermiculite, but nowhere near the ratio suggested in the Sq Foot Gardening book.
But now, all of my beds are pretty much filled to the top with soil (ie. not enough room to mix in a lot of peat moss + vermiculite).
So, should I take out a portion of the soil to make room for the peat moss + vermiculite (and just put that soil in my big compost pile to reuse down the road)?
