Pests
Mealybugs on Ferns
Commonly affects: Various ferns (Polypodiopsida)
White, cottony masses cluster where fronds meet the main stem or crown, secreting honeydew and weakening the plant.
Potential Causes
- 1Warm, humid, sheltered conditions favouring mealybug establishment
- 2Introduction from a nearby infested plant
- 3Dense growth 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 the crown and stem junctions
- 3Isolate the affected plant until cleared
- 4Repeat treatment every 7-10 days for several cycles
Prevention Tip
Check where fronds emerge from the crown carefully â this sheltered spot is where mealybug colonies often establish first.
