scale on Jade Plant
Quick answer
If your Jade Plant has scale, the most likely cause is: Scale insects (Diaspididae/soft scale) on jade plants appear as uniform raised bumps on stems and leaf undersides. Armored scale forms hard waxy tests that protect nymphs from contact treatments. Early-stage infestations show plant health overall, but crawlers (mobile nymphs) spread rapidly in stagnant air conditions typical of indoor environments.
Start here:
- 1. Confirm ID: Check for uniform raised bumps that pick off easily without plant damage
- 2. Manual removal: Gently pick off scales with tweezers or fingernail, focusing on stems and undersides
