What's eating my curio citriformis?

String of Tears (Curio citriformis) is susceptible to mealybugs, which nestle among its teardrop-shaped leaves, and spider mites in dry conditions. Root mealybugs can also attack below soil level, making detection tricky. Fungus gnats follow overwatering. Inspect both foliage and root zone when the plant looks unexpectedly weak.

White cottony wax at leaf bases and stem nodes; leaves shrivel and drop prematurely Spot-treat with isopropyl alcohol; apply neem oil spray to all surfaces weekly for at least 3 weeks

White waxy colonies on roots visible when unpotting; plant wilts and declines despite correct watering Unpot, rinse roots thoroughly, soak in diluted insecticidal soap solution, repot in fresh dry mix

Pale stippling and fine webs on teardrop leaves; leaves lose translucency and appear matte Rinse foliage; raise humidity; treat with insecticidal soap or neem oil every 5–7 days
