That would be pretty close to our natural soil. I'm in no way an expert on soil, but we mostly have humus on top of ground rock, not in very thick layers usually. And the blueberries thrive in that, alongside the pinetrees and lingonberries.Thank you. I will have to grow them in containers here as we have heavy clay soil but I will add peat moss and mulch with pine bark mulch.
Here the chickens have helpfully dug up a sample of what the soil looks like.
