Short answer
Jade plants typically develop curling or shriveled leaves due to severe underwatering or, conversely, early signs of root rot from overwatering. The most reliable fix is to inspect the root system for health and adjust your watering schedule to ensure the soil dries completely between soakings.
Curling leaves on a Crassula ovata can be alarming as the plant usually displays smooth, plump foliage when healthy. While this symptom is rarely fatal if addressed early, it serves as a critical indicator that your jade is struggling with its moisture balance or environmental stability.
When a jade plant goes too long without water, its leaves will lose their turgidity and begin to curl or wrinkle as the plant consumes its own stored reserves. This is the plant's natural response to prolonged drought conditions.
Check: Check the soil; if it is bone-dry and pulling away from the sides of the pot, the plant is likely dehydrated.
Fix: Give the plant a thorough soak until water drains from the bottom, then return to a schedule of watering only when the soil is completely dry.
Excess water sitting in the pot prevents the roots from accessing oxygen, leading to rot that prevents the plant from absorbing any hydration at all. This results in curling leaves that may feel soft or look discolored rather than just thin and crispy.
Check: Gently unpot the plant to inspect the roots; healthy roots should be firm and light-colored, while rotted roots will be black, mushy, and foul-smelling.
Fix: Trim away all blackened, mushy roots, repot in fresh, well-draining succulent soil, and reduce watering frequency significantly.
Jade plants are sensitive to extreme heat or cold drafts, which can cause the leaves to curl as the plant attempts to minimize surface area and transpiration. Exposure to direct air from heating vents or freezing window panes is a frequent culprit.
Check: Observe the location of the plant; if it is positioned directly in the path of an AC vent or a very drafty window, environmental stress is likely.
Fix: Relocate the plant to a stable spot with bright, indirect light away from any direct heat or cold air sources.
When to worry
You should take urgent action if the curling leaves are accompanied by a mushy or darkening stem base, as this indicates advanced root rot that may require cuttings to save the plant.

Diagnose my Jade PlantNo, jade plants prefer low humidity and misting does not effectively rehydrate the leaves. It can also encourage fungal issues, so it is best to stick to soil-level watering.
There is no set day, but generally every 2-3 weeks. Always check if the soil is 100% dry before adding more water.
If the leaves were curled due to mild dehydration, they will often plump back up after a good watering. If they are shriveled due to rot, they likely will not recover and will eventually fall off.
