What's eating my ceropegia haygarthii?

Ceropegia haygarthii, a succulent-stemmed vining houseplant, is most frequently attacked by mealybugs at its stem joints and in its tuberous root zone. Spider mites can appear in dry air. The waxy stems and tubers can also harbour root mealybugs, which go undetected until the plant shows wilting or stalled growth.

White fluffy deposits at stem nodes and leaf axils; honeydew makes stems feel sticky Dab with 70% isopropyl alcohol swab at each infestation point; spray plant with diluted neem oil; check soil surface for root mealybugs too

Wilting and slow decline despite normal watering; white powdery wax visible on roots and tubers when unpotted Remove from pot, shake off soil, rinse roots, treat with a neem oil soil drench, and repot in fresh fast-draining mix

Tiny pale speckling on leaves and stems; fine webbing at internodes in very dry indoor conditions Increase humidity; spray with insecticidal soap or neem oil solution every 5–7 days for 3–4 weeks
