Roughly two weeks ago, 2 of my dens started failing fast. One of them I am sure is a goner. Leaves (including new growth) rapidly turning yellow and falling off. If if it was just one, that'd be fine, but on one plant the stems decided to yellow up as well.
The only change was that I upped the humidity a little. Have had them for over a year, and they spend the summer outside in a MUCH more humid environment.
It won't let me post a url as a link, or link the images straight up, or attach images so here's the url of what I"m talking about. Sorry for cellphone quality images:
