Just for grins I dug down 12-inches below the surface of one garden and tested that soil. The test strip color was between eight (8) and nine (9) showing the soil at that depth is more toward alkaline. I know some of the plants roots will grow that deep so I will till a bit deeper this Fall.
I did two more test in each garden at about 6-inches depth and they all showed almost exactly the same as on the surface which was a 7.
This is all good to know.
