Pests
Mealybugs on Colocasia
Commonly affects: Colocasia esculenta (Taro / Elephant Ear)
White, cottony masses cluster where leaf stems meet the main plant, secreting honeydew and weakening the plant over time.
Potential Causes
- 1Warm, sheltered conditions favouring mealybug establishment
- 2Introduction from a nearby infested plant
- 3Dense growth at the base providing hidden shelter for colonies
Solution Steps
- 1Dab visible colonies with a cotton swab dipped in rubbing alcohol
- 2Spray thoroughly with insecticidal soap, reaching into stem junctions and the base
- 3Isolate the affected plant from other houseplants until cleared
- 4Repeat treatment every 7-10 days for several cycles
Prevention Tip
Check where leaf stems meet the base of the plant carefully â this sheltered junction is where mealybug colonies often establish first.
