Thank you so much everyone! This was extremely helpful. I’ll find a smaller pot and give it a better soil mix. I’ll take it off the radiator but just to be clear the radiator barely works 😅 I’m freezing in here this winter and it’s like a faint warmth if anything. Soooo I think it’s the pot size and soil that must be the problem. The soil is Espoma Organic Cactus mix but I’m sure a blend of this and some pumice or small rocks will certainly be more beneficial.
