I've long wondered about whether acid vs. basic makes any
difference. Years ago it was said that Drosophyllum NEEDED
basic soil. I've grown it in what I presume to be acid soil
with no problems. I mean, do these botanists actually run
around with litmus paper to test the soil mix they find the
plants growing in? (seriously!)
