Hi! I got these cacti as a gift. Looks to be three different kinds so a little hard to identify in planta. Anyone have an id on any of these three? I don’t really know anything about cacti, should I leave them in this little pot? I haven’t even tried to look at the roots because it’s in my office where I don’t have tongs. I assume it needs just a teeny bit of water once in awhile, and a shallow pot. Any care tips for cacti would be appreciated!
