leaf spot on Pothos

Quick answer

If your Pothos has leaf spot, the most likely cause is: Fungal leaf spot disease on pothos (Epipremnum aureum) caused by soil-borne pathogens (Fusarium, Pythium, or Phyllosticta species) that infect leaves when roots are compromised by prolonged soil moisture. Pathogens travel through vascular tissue to leaf tissue, producing characteristic interveinal spotting patterns distinct from edge-based fertilizer burn.

Start here:

  1. 1. Inspect roots by gently unpotting; trim blackened/mushy roots with sterilized shears and repot in fresh well-draining aroid mix
  2. 2. Allow soil to dry completely between waterings; use finger test or moisture meter to verify top 2-3 inches are dry

Why Pothos gets leaf spot

Epipremnum aureum

Fungal leaf spot disease on pothos (Epipremnum aureum) caused by soil-borne pathogens (Fusarium, Pythium, or Phyllosticta species) that infect leaves when roots are compromised by prolonged soil moisture. Pathogens travel through vascular tissue to leaf tissue, producing characteristic interveinal spotting patterns distinct from edge-based fertilizer burn.

How to reverse leaf spot on Pothos

  1. 1

    Inspect roots by gently unpotting; trim blackened/mushy roots with sterilized shears and repot in fresh well-draining aroid mix

  2. 2

    Allow soil to dry completely between waterings; use finger test or moisture meter to verify top 2-3 inches are dry

  3. 3

    Improve air circulation with fan on low speed and maintain 40-60% humidity to prevent fungal spore germination

  4. 4

    Apply systemic fungicide (thiophanate-methyl or propiconazole) following label dilution rates for houseplants if spots continue expanding

  5. 5

    Quarantine affected plants and sterilize all tools with 70% isopropyl alcohol between cuts to prevent cross-contamination

Keep leaf spot off this Pothos

Water only when top 2-3 inches of soil are completely dry; wait for foliage tips to just begin drooping as a watering cue. Use well-draining aroid mix with 30% perlite minimum. Maintain 40-60% humidity with active air circulation (small fan) to prevent spore germination on leaf surfaces.
