Hi! I really really want to keep plants in my dorm room, but unfortunately I have the opposite of a green thumb. I have a bloody red thumb. I have destroyed more than a few cactuses (not succulents, but cactus cactuses) and other plants, but I can't figure out what I'm doing wrong. I feel like I'm overwatering, and soon enough it seems like I'm underwatering. So, my question is, how much do I water cactuses? What else do I need to do to take care of them? Is there another kind of houseplant I can water daily/weekly that might be easier? It's hard for me to keep up with infrequent habits, but I really want to have a plant in my room. I've tried looking this stuff up but all the information seems to conflict and I get confused. Thank you!
