Hello! I've just gotten my second maidenhair, my first one did well, but my dad forgot to water it and we will see if it comes back. Anywho, I put it in a 2 gallon container with is 14" tall, for the added humidity, and the plant is already at height. I'm not sure where to find a container taller than that or should I just trim back the fern or divide it? Thank you for your help!
