What's eating my creeping broad-leaf sedge?
Spider mites (Tetranychus urticae)
Signs: Tiny pale spots or stippling on leaf surfaces; fine webbing under leaves; leaves dry out and brown at tips in heavy attacks
Control: Boost ambient humidity; wipe leaves with damp cloth; spray thoroughly with insecticidal soap or diluted neem oil on all leaf surfaces every 7 days
Fungus gnats (Bradysia spp.)
Signs: Larvae feed on roots in potting mix; surface-skimming adults are a nuisance but root damage slows growth in young plants
Control: Allow compost surface to dry between waterings; apply Bti (Bacillus thuringiensis israelensis) drench; place yellow sticky traps near the pot
Mealybugs
Signs: White fluffy wax deposits at leaf bases and sheaths; foliage yellows and growth stalls in heavy infestations
Control: Dab with isopropyl alcohol on a cotton swab; spray with insecticidal soap; isolate the plant immediately to prevent spread to nearby houseplants

What is eating my creeping broad-leaf sedge?
Grown as a houseplant, Carex siderosticha 'Variegata' is most susceptible to spider mites when indoor air is dry, causing fine leaf stippling and webbing. Fungus gnats breed in damp compost. Mealybugs occasionally colonise leaf sheaths. Good airflow, moderate watering, and regular misting deter most indoor pest problems on this sedge.
