Re: In-ground Planting Mix

joe---

i've never tested the ph in the beds.  the acidification is a natural and
expected process.  i think that it's not so much a matter of aroids
preferring acidic conditions as matter of their NOT preferring alkaline
conditions.  generally speaking. most of what we grow are epiphytes on trees
in their native habitats......but then there's anthurium reflexinervium that
grows on limestone rocks as do many of the alocasias!  so, i simply try to
keep it 'even'.  most plants, not just aroids, generally prefer between 5.6
and 6.6 ph and at that level, will properly absorb at least some
nutrients....... if my poor memory serves.  the old, tried and true Selby
epiphyte mix includes lime.

lynn, at what ph does one add lime?  It has been my experience that most
aroids prefere acid.  The ph would be most helpful to all.  Joe
