Hadley recommended Orchiata mix. (So does Bill Goldner for Phrags). He said it gave him longer time between repotting as Paphs should be repotted frequently, so instead of every year repot, he could go 2. Bill said it extended his repot from yearly to 18 months for phrags.


Here was Hadley’s mix:

Seedlings - Classic  ⅛-¼”


3.5 “ - ¼-⅜” Power


4.5 - or larger ½-¾” Power Plus  (larger, 4 parts to 2 parts)


75 bark/15 perlite/10 Canadian peat.


Parvi and brachy love oyster shell or chic grit


I’ve used their recommended mixes since I heard them say this in 2021, except I add charcoal.

After 2 years UNC studies show Orchiata pH drops rapidly if 100% Orchiata, a little slower with perlite/charcoal.

Bill uses Power Orchiata in a 6” pot with perlite. He stopped using charcoal because of inconvenience if getting it. I’ll see him this weekend and verify this is still what he’s doing.


Anyone know where to get Canadian Peat?
