Eliminating a Fungal Outbreak on Indoor Mint Plants

Thick brown hair‑like clumps releasing dusty spores appeared on mint stems/leaves, making soil sticky and webby. Marjoram nearby was unaffected.

Action Plan

1. Gently cut off as much fungus as possible; discard outside to avoid spreading spores.
2. Spray entire plant (both leaf sides, stems, soil surface) with Lysol (generic OK) twice weekly for 2 weeks. Cover with a large plastic bag for 30 min after spraying to contain spores.
3. Monitor closely for recurrence.
4. Avoid overwatering mint.

Edibility After Treatment

Lysol won’t harm the plant if sprayed from 12 inches. Wash harvested leaves with a vegetable cleaner (produce section) until new growth replaces sprayed foliage.
