Hi all, new forum member here hoping someone with more knowledge than me can help identify what is going wrong with my euphorbia trigonas (at least I think that’s what it is). Photos attached. Basically, one of the stalks became soft and discoloured and eventually withered away as shown in the photos. Not sure whether the issue is over- or under-watering, or something else. I water it VERY sparsely.
Hello, welcome to the forum. :) Could I ask what type of soil you are using there? Is that pure coco chips? Does that pot have drainage holes in the bottom? If you had to guess, how many hours per day of direct sun on the plant does it get? Thanks!
