I’m fairly new to gardening but purchased some cactus’ last year. I noticed one started to develop a white spot on the side of it. I isolated this cactus into its own pot. Any idea’s what it is or what can be done to possibly cure it?
- I live in Texas.
- The cactus is typically outside unless it is too cold or it is going to rain.
- I water it once a month, unless it rains enough.
Thanks in advance!
