how often do i water my christmas cactus

The Christmas cactus only requires watering once a week, unless it's in a particularly dry climate or it's very hot. Make sure to use room-temperature water, and always allow the soil to dry out completely between waterings. If the leaves are turning yellow or the plant seems to be dropping flowers or buds, that's a sign that it may be getting too much water. Cut back on the amount and frequency of waterings, and see if that helps.
