scale on Boston Fern
Quick answer
If your Boston Fern has scale, the most likely cause is: Scale insects attach themselves to fern fronds and stems, feeding on plant sap. They appear as small, immobile bumps and can cause yellowing and decline if left untreated. Ferns are susceptible because their dense foliage provides hiding spots.
Start here:
- 1. Inspect fronds thoroughly, especially undersides and stems
- 2. Remove visible scale manually with cotton swabs dipped in rubbing alcohol
