Thanks for that info, Mamuang, much appreciated. Our house is about 100 years old now, and I’m told that the land was previously a vegetable garden. The soil generally seems pretty good, and was acidic enough to turn my wife’s pink hydrangeas blue (or blue-ish, anyway). Which I think happens down in the lower 5 range? I still have to go out and do an actual test, but yeah, it should be a bit more favorable situation for blueberries (which are probably going to be a next-year project for me, anyway).
