Corkscrew Rush – Roots Are Overgrowing Pot After Recently Being Re-potted?

Question

I was given a corkscrew rush by someone who just couldn’t handle how often it needed to be watered. Additionally, I decided to re-pot into a slightly larger container (I believe it was given to me in a 1″ and I bumped it up to 1.5″ or 2″). Now, just checked and it’s roots are already crowded in that container. Should I re-pot again? How big? Thanks!

Answer 1

You can repot it again. I'm not certain what size you said it was in because a symbol came across with it. These plants spread by rhizomes to 12 to 18 inches. Since it is a bog plant, you can go up several pot sizes as extra water shouldn't hurt it.

It is hardy in your zone 5 if you want to plant it outside. It will turn brown but the brown leaves can be trimmed back in the spring. Just be sure to keep the soil from drying out.
