Signs of Overwatering
A soft, discolored patch forming at the base of the round, ribbed body is a serious sign of rot from overly wet soil.
Signs of Underwatering
The ribbed body can look slightly deflated or drawn in, though this is one of the most drought-tolerant plants on this entire list.
Adjusting for the Seasons
In winter, especially in a cool room, this cactus may need no water at all for 6-8 weeks - when unsure, always wait rather than water.
Pro Tip
This slow-growing cactus can eventually reach a substantial size over many years - it is one of the easiest plants on this list to accidentally kill through kindness (overwatering) rather than neglect.
