Vine Weevil on Outdoor Succulents
Commonly affects: Various succulents (Crassulaceae, Aizoaceae, and others)
The plant wilts and declines without an obvious above-ground cause, and adult weevils may be seen at night, with C-shaped white grubs visible in the soil when checked.
Potential Causes
- 1Vine weevil larvae feeding on roots underground, often going unnoticed until decline is significant
- 2Adult weevils laying eggs in the soil near outdoor succulent plantings
- 3More common in outdoor container or garden succulents than strictly indoor ones
Solution Steps
- 1Check the soil for C-shaped white grubs if decline seems root-related with no other obvious cause
- 2Apply a biological nematode drench specifically targeting vine weevil larvae
- 3Hand-pick adult weevils at night when they're active, using a torch
- 4Repot into fresh soil if grubs are found, discarding the old contaminated soil
Prevention Tip
Vine weevil is primarily an outdoor garden pest â if an outdoor succulent declines with healthy-looking foliage but no obvious cause, check the roots for grubs.
