Scale on jade plant

jade plant with scale

What's Happening

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.

How to Fix It

  1. 1

    Confirm ID: Check for uniform raised bumps that pick off easily without plant damage

  2. 2

    Manual removal: Gently pick off scales with tweezers or fingernail, focusing on stems and undersides

  3. 3

    Spot treatment: Wipe with 70% isopropyl alcohol on cotton swab to kill nymphs and residue

  4. 4

    Apply neem oil or insecticidal soap weekly for 2-3 weeks to target crawler emergence

  5. 5

    Isolate and monitor 4 weeks; inspect weekly for crawlers

How to Prevent It

Quarantine new plants 2 weeks; promote airflow with fans, maintain bright indirect light and low humidity (<50%); avoid over-fertilizing to reduce sap attractants; weekly leaf inspections during routine care.
