I suck. The cactus plant on my desk is dying. I spray it 8 times every week as the directions said. OMG WAI I FAIL IN LYF.
you are a girl after my own heart. I've killed plenty of cacti. is it getting direct sunlight?
Maybe to much water, and they like the water from the bottom not sprayed on them
They don't get direct sunlight, it said to keep in shade.
Ohhh I have been spraying on them but I'll focus on the soil now. Maybe that's why 
Yeah, water from the bottom. Most plants prefer that.
I'd water it at the base, and let it dry out again before watering it the next time.
Yeah that's the way
