Night Blooming Cactus Has Brown On Leaves.
My cactus leaves have holes in them and turning brown. Don't know what's causing this. Plant is potted, indoors, indirect light, and about 4 ft tall, sprouting leaves and those longggg stems! Dont "see" any bugs; moved it in 2019 from fl, it was on a covered lanai and beautiful - even bloomed last year (and this was from a cutting); now living in southern NC, inside now. Can you tell me what the problem is; should it be moved elsewhere (have no shade outside to put in summer either), how to treat it? Don't want to lose it...lost a precious begonia last year - outgrowing itself in FL on lanai, but moved it to NC, died (was also indoors and indirect light). Thanks for your immediate help.

I would have to say that the new environment is against you, here! The Cereus will prefer hot temperatures. (They like it up in the 90's and 100's) They, also, really need that humidity to be happy, as well as full sun unless it is overly hot. Caring for these, indoors, will be quite tricky, as it may require extra humidity, heat, and light.
