How does Humidity effect succulents and cactus?

Succulents do not like humidity as it can lead to fungal problems which end in rot and your plant losing leaves and often dying. If you have recently watered  your succulents and it is humid or raining outside, please consider moving to a dry area with minimal humidity (inside) especially if these will be used for an event.  Wet soil and humid air are a bad combo for succulents as it does not allow the soil to dry out properly and quickly!
