What's eating my sansevieria gracilis?

Sansevieria Gracilis has narrow, wiry leaves that offer less surface area for pests, making serious infestations relatively rare. Mealybugs and spider mites are the most likely indoor visitors. Root mealybugs can colonise the rhizome undetected in perpetually damp soil. Keep compost drying out between waterings to deter most problems.

White waxy deposits at leaf bases and along the rhizome; affected sections yellow and the plant fails to produce new growth. Remove with an alcohol swab, then spray all surfaces with insecticidal soap or neem oil. Check the rhizome when repotting.

Pale streaking and silvery dots along the narrow leaf faces; fine webbing may appear where leaves emerge from the base. Increase humidity and wipe leaves down. Apply insecticidal soap or neem oil spray every 5–7 days until no signs remain.

Invisible above ground; roots show white powdery colonies and the plant slowly declines without obvious cause. Inspect roots at repotting, treat with a systemic insecticide drench, and repot in fresh, well-draining mix.
