While I still think healthy soils are incredibly hard to modify acidity, blueberries simply won’t grow or at least thrive on my soils descended from limestone parents.
In the fall the pH was over 8. The compost layer is buffering it closer to neutral but the subsoil (pictured above) is still alkaline.
So I rented a tiller, hence the break from regularly scheduled programming. I’m on the clock.
Thus I will follow up tomorrow with the details to my strategy with the tiller.
