Hi,I have an unusual plant I gréw from a cutting someone gave me a couple of years ago here in Maine. I originally thought it was a variety of Christmas cactus but now I think it's some type of weberocereus. I haven't cracked the code to growing it but see that it hangs in there growing despite now having a few black edged leaves that seem to creep and some trails of parasitic creep(spiders)?. Is it just that now in a very cold winter the plant is flailing? Or it has mites? I've sprayed it with neem oil frequently and misted it with water, and kept it under grow lights but it now seems dormant so I almost never water it but it's not shriveling up. Does anyone have hints on this

Not a Weberocereus as only a few of them are in cultivation anywhere in the world. Most likely a Epiphyllum (orchid cactus). I don't see any insect damage but there is a lot of physical damage. Do you by chance have a mischievous cat?

Wéll, i trimmed off the black shrivelly portions (some is still creeping in from the edges as, hopefully, you can see on the pictures). No cats since the plants are in a business office. Maybe some insects? The trail cut in one leaf in the pictures is maybe some type of insect chewing?

No, the leaf was bent in half. Cleaning people?

Put cinnamon on the edges were it is turning black. Cinnamon is a natural fungicide.

I agree likely an Epiphyllum. There are many varieties. In your northern chilly climate, likely it will never have thick lush growth unless you give it more light, but you may get some blooms eventually, which can be quite spectacular! It might not have bugs at all, mine seem quite resistant and I just don't need to use any pesticides on them.

Thank you! I do have grow lights and I think I will move it home to a sunnier window.

What an interesting plant. I just thought to mention that neem oil can cause damage to the leaves if over-used. So, I'm wondering if the black edge was there before you sprayed with oil, or if it showed up afterwards? And maybe it's neem oil damage and not any type of bug problem? It seems to be really minor, though, which is good.

Interesting, thank you! I did not know that about neem oil. It may well have appeared after I started using it as a preventative. I am letting it recover now (put cinnamon on the black portions and it seems to be drying it up), am misting it and waiting for February for it to wake up. Crossing Fingers!

I'm wondering if it might be this Rhipsalis:

No Tiffany, it is not, I have that plant!
I would suggest to take that plant out of this somewhat too large pot, give it fresh soil and as much sun as possible. It would surely be happy to be outside during the Summer.
