What's eating my tiger tooth aloe?

Tiger Tooth Aloe (Aloe juvenna) is a compact clustering aloe most commonly troubled by mealybugs, which hide in the tight leaf stacks. Scale insects and spider mites can emerge in dry indoor conditions. Because this aloe clusters freely, check the growing points of all offsets — pests spread fast through a dense clump.

White fluffy deposits in the narrow gaps between leaves and at offset junctions; slow growth and leaf wilt. Treat each affected spot with alcohol on a cotton swab; spray the whole plant with neem oil weekly for 3 weeks; check all offsets carefully.

Hard brownish bumps adhered to leaf surfaces; yellowing and weakened growth around affected areas. Physically scrape off scales; wipe with isopropyl alcohol; apply horticultural oil spray and repeat every 2 weeks.

Dusty pale stippling across the leaf surface; fine webbing between tightly packed leaves. Isolate the plant; wipe leaves with a damp cloth; spray with insecticidal soap or neem oil, paying attention to leaf gaps.
