I bought this golden Pothos a year ago and it looks great, healthy and growing well until recently. 5 weeks ago I pruned it for the first time (I am propagating the cuttings in water and those seem perfectly healthy). But now the new growth that is coming out from the vines is really tiny. Really tiny leaves! I am trying to figure out what the problem might be and wanted your opinion.
This plant has been living in the same spot for the last year, near a East facing window where it gets a bit of direct morning light but mostly indirect light. I let the soil go pretty dry before watering. I have been fertilising it for the past 2 months or so with a general liquid fertiliser every other watering. It has never been repotted and it is quite root-bound, as you can see in the picture. I left it like this because I read, and also experienced in the past, that these plants like to be root-bound. I wonder if I overshot here?
