bareroot to media

[slippery_biscuit]

Hey, I just received a Schombugkia and it is a pretty good size plant (maybe 18" tall). Came with a teak basket and no media. Don't know what is normal for these, but there aren't a lot of roots; there is a clump about 1-1.5 inches long.

What is the best thing I can do for this plant. I've meduim bark on hand and some orchid mix that looks meduim to fine with maybe some perlite (is that what those white things are?).

And how much water? Got some 20-20-20 fertilizer also.... A bit new at this in case it doesn't show.

Thanks,
Jeff
