Pencil Cactus

Question

I have a 5 foot tall pencil cactus. I put it outside and was unable to bring it in when temperatures dropped to freezing. It is so severally frostbitten. What to do?

Answer 1

It can take days or even weeks for frost damage to appear.
Keep the plant in a normal indoor environment.
You can prune away the dead or damaged plant material. Use gloves, as the sap can cause irritation and reactions can be serious in some people.
