Holiday Cactus Opts for March Partying

Sad Holiday Cactus

My poor holiday cactus. Leaves are turning red. This can happen when the plant gets too much sun, and/or has a magnesium deficiency. I moved it to a less-sunny area and treated it with a foliar spray of epsom salt. I'll spray again in 2 weeks and assess the situation. I will likely re-pot the plant, too.
