Can rhizome plants just go straight into east planter?

[CornAndCrawlers]

I bought a bunch of Java ferns from aquarium coop and just tossed them all straight into east planters without removing them from the plastic pots or the steel wool/whatever the moist packing medium is. 

 

If I removed the plastic and the steel wool I figure the rhizome will do better but I’m not sure how I’d get it to stay in the east planter. I don’t mind slower growth, just hoping this lazy drop and plop method I did doesn’t kill all the Java Ferns.

As long as the rhizome isn't buried the ferns should be fine to go right into the easy planter.

If the rhizome is tied or in the rock wool then it should be ok.
