Short answer
Jade plant leaves typically fall off due to inconsistent watering or inadequate light exposure. The most common fix is to establish a strict watering cycle where the soil is allowed to dry out completely between waterings, while ensuring the plant receives at least 4-6 hours of bright light daily.
When a Jade Plant (Crassula ovata) begins dropping leaves, it is often a sign of environmental stress rather than a serious disease. While minor leaf drop during seasonal transitions is normal, sudden or widespread shedding usually indicates that the plant's rigid needs for light and soil drainage are not being met.
As a succulent, Crassula ovata is highly susceptible to root rot when kept in damp soil for too long. If the plant is overwatered, the stems become soft, and the leaves will turn yellow or translucent before falling off.
Check: Check the soil moisture deep in the pot and look for mushy or blackened roots when gently lifting the plant.
Fix: Immediately stop watering and allow the soil to dry out completely; if roots are blackened and mushy, prune the damaged areas and repot in fresh, well-draining succulent soil.
Jade plants require significant amounts of bright, direct light to maintain cellular integrity. If the light levels are too low, the plant weakens, becomes leggy, and sheds its lower, older leaves to conserve energy.
Check: Observe the stems: if they are stretching, leaning heavily toward the window, or have large gaps between leaves, the plant is light-starved.
Fix: Gradually move the plant to a south or west-facing window where it can receive at least four to six hours of bright, direct sunlight per day.
While jade plants are drought-tolerant, prolonged neglect will cause them to sacrifice leaves to survive. The leaves will typically shrivel and wrinkle significantly before dropping off.
Check: Check for deeply wrinkled, thin, and brittle leaves that are not discolored.
Fix: Resume a regular watering schedule by soaking the soil thoroughly once it has dried out completely, ensuring excess water drains away freely.
When to worry
If the stem begins to turn black or mushy at the base, it indicates stem rot has set in, which can be fatal if not treated immediately by propagating healthy cuttings.

Diagnose my Jade PlantNo, you should never mist a Jade Plant. They prefer dry conditions and high humidity or excess moisture on the foliage can encourage fungal issues.
Yes, as a Jade Plant matures, it is natural for the oldest, lowest leaves to wither and drop as the stem hardens and turns woody.
If the branch is firm and green, it may sprout new leaves once provided with better light. However, if the branch is soft or shriveled, it is likely dead and should be pruned.
