The week out of town happened just after the fittonia had visibly recovered from repotting, and both of those happened about 2-3 months ago. I don't let it wilt between waterings, but I do try to wait a bit so I don't overwater. The curtains are closed but sheer, and the fittonia is close enough that I figured it would get enough light from that. However, I may be wrong on that one.
Even though it's been "in recovery" for a few months, I think the leaves are dropping at an even faster rate right now -- the edges turn orange/brown, they lose their firmness, and then they just fall off. I have a tiny prop from the same plant that the same thing is happening to, and I think it's about to only have one leaf left
Does anyone know if there a way to encourage new leaf growth at the nodes where old leaves have fallen off? I've only seen leaves grow in between two preexisting leaves on this one, so not sure if it's typical for them to grow on the now-empty nodes.
