Currently I have it in a corner that does not get a ton of sunlight and I am not watering very often... starting to think maybe I should give the cactus more of both. These can take a lot of sun, and a plant that size will take quite a bit of watering if kept in a small pot. It currently looks very...

Underwatering can lead to root rot, especially if the soil contains too much peat. Dried-out peat resists soaking up water, if you get it really dried out and then water lightly part of the root ball can stay dried out, water can actually drain past without soaking in to it.

I think I may have been underwatering the cactus but although the pot I have does drain some, the soil I have is not ideal for a cactus so it is definitely possible that despite infrequent waterings, I still could have rotte...

The withering could be a few things. How often do you water it? It could be underwatering or overwatering. Was there a dramatic increase in light?, That can cause wrinkling & yellowing, especially since it has etiolated growth. However, there is no withering or discoloration of the etiolated gr...

Hello! I have had this cactus since late 2014 and it is native of South Dakota. It started as two "segments" and grew well for a long time but starting this summer it started to not look healthy and very recently it has shriveled significantly. This summer I fertilized it a little with som...
