Christmas cactus looks wilty

Question

Is it getting too much or too little water? What is causing that?

Answer 1

Here is a link with growing information.

Check the soil, does it feel dry or moist? To dry can cause wilt and to much water and roots sitting in soggy soil can cause root rot.
Make the adjustments you need.
