Catasetinae Repotting

[Clawhammer]

Hello all:

I discovered this year that the catasentinae family is for me and I have acquired almost 20 of these plants mostly from SVO. (Thank you Fred Clarke!).

All of my current plants are in their 2.5" plastic nursery pots in 100% sphagnum and have begun to spike / drop leaves. After debating semi hydro I have decided these will all be planted in 100% sphagnum in 4" terra cotta pots.

Question: I know the instructions are to wait until roots are 3" long in the spring before repotting but considering I will just be pulling their nursery pot and dropping them into a larger container and filling around the existing sphagnum with the same kind of potting media, is there any harm in me doing it now?

Also regarding watering / fertilizing, I have stopped fertilizing on November 15th and reduced watering. I let the plants become fully dry for a couple days before watering. Does this sound about right for plants dropping leaves and throwing up spikes?

Thanks!
