I got these Cacti and succulent three days ago. I havent done anything yet as far as watering or repotting. I know how to take care of the succulent as I've grown them for a few years but im unsure of the cacti. When should i water or repot? Can they share a pot? Do they prefer top or bottom watering? And should my soil has the consistency of succulent or have more pebbles/sand in it? I also sometimes add used coffee grounds is that ok? I havent had a problem but obviously cacti are different. Apparently one is a mini barrel cactus and the other is a moon cactus. The dirt seems fairly dry and i felt the moon cactus and it feels firm. They were purchased from a home depo so who knows what kind of horrible soil they are in LOL 🤣
