What's eating my mother fern?
Scale insects
Signs: Hard or soft waxy bumps along frond midribs; yellowing fronds and sticky honeydew
Control: Remove manually with a damp cloth or soft brush; treat with diluted neem oil; repeat every two weeks until clear
Spider mites
Signs: Silvery stippling on frond surfaces; fine webbing in dry conditions; fronds shrivel
Control: Mist frequently to raise humidity; wash fronds under lukewarm water; spray with insecticidal soap or neem oil every 5–7 days
Mealybugs
Signs: White woolly masses at frond bases and around plantlets; sticky residue; stunted growth
Control: Dab with alcohol-soaked cotton swab; spray with insecticidal soap; isolate plant to prevent spread
Fungus gnats
Signs: Larvae feed on tender roots in damp compost; adults emerge from soil surface
Control: Let the topsoil surface dry between waterings; place yellow sticky traps; use Bti soil drench for persistent larvae

Mother Fern pests — FAQ
What is eating my mother fern?
Mother Fern (Asplenium viviparum) is a delicate houseplant fern prone to scale insects and spider mites, especially in low-humidity rooms. Its tiny plantlets produced on frond tips can harbour mealybugs. Fungus gnats thrive in its consistently moist compost. Boosting humidity and avoiding waterlogging are the first lines of defence.
