This is a sturdy healthy looking cactus. The care is easy. I did use soil specifically for succulents.

I love this little guy. Low maintenance. Just wants some sun and sandy soil. And a couple friends in a succulent planter never hurt.

Whenever you think you should water it, wait a week and then go to water it but before you do, wait another week and then water it

Very easy to look after and look really pretty, just be careful when handling them as it’s easy to get barbed

Super slow growing but hardy cactus. Unfortunately they grow so slowly that if your husband accidentally knocks it to the floor and decapitates it, it will take time to recover but it won’t kick the bucket quickly so that’s good! Easy to deal with and interesting looking and a great conversation piece!
