Jade Plant White Residue: Mineral Deposits or Mealybugs?

Deb's healthy, blooming jade plant has white sooty powder on branches that wipes off. Some leaves shrivel but respond to increased watering.

Diagnosis

Most likely: Mineral residue from previous dehydration. When jade leaves/stems get too dry, they can leave powdery deposits. Rinse or wipe off; increase watering frequency.

Watering guideline: Water when top ½ inch of soil is dry (top inch for 8+ inch pots).

If cottony texture: It's mealybugs. Treat with 5:1 water:alcohol spray. But description suggests mineral residue.

Care Reminder

Jades need bright light (direct sun ideal), thorough drying between waterings, and minimal fertilizer. Blooming indicates good health.
