I am trying a new mix for my Winston Churchill cross after reading this article by Mahon:
Recent Studies Upon Paphiopedilum Cultivation - Orchid Board
The plant has always been fickle... I've only gotten it to bloom once in 5 years. His article makes alot of sense... The only time this plant bloomed was when I grew it in previously-used osmunda after repotting a Phal. I had ready that Paphs are one of the few orchids that do like USED mix/osmunda. I suspect it did so well because the osmunda was already supporting the fungus that Mahon is referring to.
I followed the recipe quite closely! (I added a crushed oyster shell from the beach, which I pulverized with a hammer after washing it) My only concern is that this mix seems a bit too soil-like, but what the heck, we'll see! Has anybody else tried this with good results??????
