The soils of our region are acidic due to the thousands of years of the Redwood forests. Lime is my second name except for my blueberry patch. Huckleberries thrive on our spread with many growing out of the old Redwood stumps cut around 1900 ~
Oh wow.... what an interesting set of circumstances and what gorgeous pictures! Not much like that in Oklahoma!
We really do have to know our soil and the chemistry of them, and the plants that like those soils... as well as what we can do to amend them for other plants for which the soil is not quite right.
