Six weeks after filling the E bed, above, it had composted down nicely to the level below. The greenery at the front of the bed are some peas that came up fromt the pea straw. This is the bottom leg of the E that's filled with soil rather than the no-dig layers, a bit of bonus nitrogen fixing.
So it was time for another layer of sheep/cow poo blend, some dolomite and wheat straw, but only on the no-dig part of the bed. I watered this in then spread some blood & bone/sulphate of potash mix over the top. This brought it back up to the level below. I'll be planting in this at the begining of October. Maybe mid September for the cucumbers.
