49+ My Cactus Has Brown Spots. Sun scald happens when cacti are placed in a window that receives. My cactus has this brown areas growing across the surface since a week ago.
What can i do to help him?
Cacti tend to do best when they are watered thoroughly, and then left until the potting media has dried fully before being watered again. I bought a cactus as i wanted to see if i could keep something alive but it went brown after about 1 month and died. And so much scratches over it, and a bit of it looks like it has been eaten by some bug. My cactus has this brown areas growing across the surface since a week ago.
