Dying Cactus Revival
A couple days ago I noticed my small indoor cactus was slightly tilted and it's root visible from the back. Today I realised it was considerably wilted, much smaller than its original size and yellow. Is it too late to save it? I have watered it and put it out in direct sun today.
