Re: In-ground Planting Mix

From: Aroideae at aol.com on 2001.07.17 at 13:24:38(7056) 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 +More 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
