I am in love with this plant. It is my first Cereus. I have had it for 6 months and it has been super healthy!
It normally sits in the sunniest spot of our lounge.

However ... today was a super sunny day - and I got home the leaves have gone a bit yellowy brown and super wrinkly (it is normally waxy smooth) - I have misted it with water as I think it is sunburnt(?)

What does it have? and how do I save it?

I purchased special cactus soil for it too :( !!
