What's eating my reinwardtii haworthia?

Haworthiopsis reinwardtii (Reinwardtii Haworthia), with its upright tubercled columns, is most commonly attacked by mealybugs that shelter between the white-spotted leaves and at the stem base. Root mealybugs and spider mites occur secondarily. Its columnar, clustering habit means pests can spread between offsets; inspect each stem individually and treat the whole clump together.

White cottony deposits between the closely set tubercled leaves and at the base of each upright stem; leaves yellow and the column may lean or soften Work 70% isopropyl alcohol into crevices between leaves with a fine swab; spray whole clump with insecticidal soap; repeat weekly for a month

Slow wilting and halt in growth across the clump; white powdery wax on roots and the base of stems when unpotted Lift and separate the clump, wash roots thoroughly, soak in dilute insecticidal soap, let dry, and repot each offset in fresh succulent mix

Fine webbing spanning the gaps between leaves on the column and dusty silvery speckling on white tubercles Spray with insecticidal soap or neem oil; ensure good ventilation; repeat every 5–7 days for at least 3 rounds
