I feel like it has good drainage.. there's a hole in the bottoms then small rocks and then cactus soil with perlite and charcoal mixed in to help it. Thanks for the watering tip. I've only watered it once but who knows how many time they watered it at OSH before I bought it. I've gotten such mixed reviews for watering. Some people have told me once every two weeks other says 4 times a year. I didn't plan on watering it again until the end of August but then it started doing this and the sunken in part was there... Thanks again!
