# I'm having to repot my Cobra due to uncontrollable fungus gnats.…

_Posted by Melinda on 2025-05-25_

I'm having to repot my Cobra due to uncontrollable fungus gnats. Should I separate them? Also should I chop \& prop them since they are so long with no aerial roots? And how do I cut them without killing them? Can I cut the "vine" into multiple segments?

I recently repotted due to fungus gnats. I only repotted 5 of my 7 plants. It made a significant difference. For pruning, I've pruned my philo a bit since she was long and stringy. She's now very full.

Thanks!! I pruned them back pretty good. They were very long and stringy. I've got 40 or so plants. I'm just doing the "worst" ones then taking a layer off the top and replacing. My fingers are crossed.

She'll be putting out new growth in no time. I chopped my cobra a few months back, and she grew 2 new stems, one with all white leaves, and the other one with green and white. They're fast growers IMO, but as for propagating, this has been the most challenging for me, I hope you have better luck with your cuttings. They took a very long time to root, and some didn't make it. Good luck and I would love to know if you find a surefire way to prop these.
