ph for columbines
 

Does anyone know whether columbines prefer acidic soil or neutral? I have
them do OK for a short while in acidic soil but then they seem to just
disappear.

Same thing with astilbes. I think I am getting something important wrong
here. I know for nasturtiums and lavendar I bring in sand and put them in
mostly sandy soil and they do fine. I haven't been able to locate a
resource to tell me about astilbe and columbine, though.

I think I remember reading in a recent issue of Horticulture magazine that
columbines grew wild in alkaline soils so it wouldn't hurt to throw a bit of
lime their way to help out.
