Shamrock Plant Brown Spots: Rust or Spider Mites

Shamrock leaves have brown spots and brown edges.

Possibilities

• Fungal rust: Orange pustules on leaf undersides.
• Spider mites: Tiny, may leave fine white webbing.

Treatment

• If mites: Bayer Advanced Tree & Shrub Insecticide soil drench—systemic, season-long.
• If rust: fungicide; improve air circulation.

Inspect undersides closely.
