I really just registered to find out what is happening with my cactus, but perhaps once I know more I'll get deeper into. This one lives in a small flat in rainy London (poor thing) and was doing just fine for years when suddenly it grew a lot and then these long tentacles came out. This started a few months ago.
So, which cactus is this and why the tenctacles? Is it a disease or completely normal. Should I do anything? I couldn't upload an image so the I used my profile image instead - that's the cactus I'm talking about...
All help and suggestions appreciated!
