Any idea what’s going on with my fence post cactus? The middle/lower section started looking sucked in and skinny compared to the top. The newer growth towards the top looks normal.
It also has some spots. The cactus still feels firm, but also kinda soft at the same time, almost like it’s lacking water or dehydrated. It’s planted in ground in full sun.
Not sure if this is from underwatering, root issues, pests, or something else. Any ideas or recommendations?
