Last year I had a Pinguicula primuliflora growing great. As fall came I decided to repot the plant into a mix of peat, perlite, and LFS, In equal parts, from a 3" pot to about a 5" pot. Over time the plant got smaller and smaller and eventually became effected by rot. It looked to be potted in pure peat when I repotted.
So the beginning of this year I bought another one, and repotted it with the same mix as above. The plant again is getting smaller and smaller.
What have you folks found to be the best soil mix for this plant?
Go ahead and tell me to add sand. I just bought a 50 lb bag of super special white quartz pool filter sand.
