My mom found this beautiful Euphorbia horrida hybrid in a nursery a couple of years ago. She has a history of killing even the toughest plants (mostly underwatering), but her small cactus collection thrives. Possibly even more than my own succulents.
I found that overthinking everything about a plant’s needs isn’t necessarily a good thing. You don’t always need expensive pots and soil mixes, gadgets, fertilizers and calendars to keep a cactus alive. Just give it lots of light + very little water and it will be happy!
