Split rhyzome, trim back for winter, or leave it be another year?
The title really does have all three of my questions.
This is growth from last November. Inside until May then out with the VFTs. After our NC cold snap:
It's very crowded so do I unpot, split the rhyzome and have 2 pots?
Trim away, if so, which ones?
Leave it be and let it do its thing?
