Don't drown them. Fish emulsion smells bad but helps plants green up. I think they like medium light. They aren't usually very fussy.

I have moved the plants to a spot where they get more sun and less water and have Neptune Harvest fish and seaweed fertilizer. Good start.
Now does an one know if regular potting soil should be used or something more gritty like a bonsai soil or combination of both?

Hi
Don't know if I can be of much help as I grow them out doors where they get downright weedy lol.
First what kind of Philo ?? Most are not particularly sensitive but there are a few that are.
I grow them in soil,water ,even in a clump of sphag. on a wall. I can't remember ever having a cutting fail in any situation. lol.
Unless you're growing one of those high altitude types any type of soil should work. gary

Don't really know what kind they are. They look like young cut leave Phil.
They are seedlings that came from Disney world in FL. and are growingin 4" pots. They will be indoors in late fall & winter.
