Mature Jade Plant Leaf Drop: Normal Aging vs. Pest Issues

A large, old jade plant (2 ft tall, 2.5 ft wide) drops leaves with shiny glitter-like residue after drying. Owner waters only when completely dry. Questions about repotting.

Assessment

• Normal leaf aging: Older leaves naturally yellow and drop as plant grows.
• Shiny residue: Could indicate honeydew from sap-sucking insects (scale, mealybugs) or mineral deposits from water.
• Repotting: Only needed if roots circle the surface or plant is toppling. Large jades prefer being slightly root-bound.

Action Items

1. Inspect leaf undersides and stem joints for pests (cottony masses, brown bumps).
2. Review Garden Helper's jade plant guide for pest photos.
3. Maintain current watering—it's appropriate.
4. If repotting, use shallow wide pot with fast-draining mix; jade roots are shallow.

Old jades develop thick trunks and become tree-like. Some leaf drop is inevitable. Focus on pest detection rather than repotting unless structurally necessary.
