Hi, everyone. A few weeks ago I pruned back my Fittonia to keep it more compact. The main plant responded well and it has some new growth slowly emerging from the cut points. Out of curiosity I stuck some of the cuttings in water, to see if they would root. So far all have died but one...no surprises there. This one is managing to stay alive, but it is also just sort of sitting there, not showing any signs of really doing anything.

Has anyone ever tried to root a Fittonia from cuttings? I hear they are not very vigorous propagators but I was curious.

I've had a lot of trouble getting a lot of plants to do well for me, but for some reason Fittonia have been one of my success stories.
I rooted cuttings in water without any problems, and also just popped some back into the pot--which stays pretty moist. They all did fine. I did have slightly longer cuttings to start with, I'm not sure how much that matters. If I had it to do over, I don't think I'd bother with starting them in water, but I know that some people prefer that.
It may just be a little cool for them right now. A lot of plants pick up speed when the weather gets warmer and the days get longer. As long as the leaves are alive, I'd just give it more time.
If I had known their reputation, I never would have given them a try. I first got them for a low light office but they ended up back home with me for the pandemic. At least they let you know when they need to be watered!

Fittonias wilt very easily. Cuttings don't have roots developed enough to supply the leaves with the water they need. They transpire water through their leaves quickly. You can try to maintain the humidity by placing the cutting inside a clear plastic bag that you seal, creating a mini greenhouse. After roots have formed, you can gradually open up the plastic tent over a period of a week or so.
