Pothos (Epipremnum) Brown Spots: Natural Blemishes or Water Issues

Likely Benign

Smooth, non-raised, non-scratchable brown spots only on leaf undersides, not all leaves = natural blemishes or minor mineral deposits. Not a disease.

Possible Contributors

• Hard tap water: Excess minerals burn roots/leaves. Switch to filtered/distilled.
• Inconsistent watering: Let top 1/4 soil dry, then thorough soak.

Action Plan

1. Use filtered/distilled water.
2. Water consistently: dry 1/4 → soak → drain.
3. Monitor: if new leaves emerge clean, problem solved.
4. If spots spread/become raised → email photos for re-evaluation.

General Pothos Care

• Bright indirect light (tolerates low light but variegation fades).
• Well-draining soil, pot with drainage.
• Fertilize monthly half-strength spring–fall.
• Trim to shape; root cuttings in water/soil.

Your giant pothos is likely fine. Fix the water, watch new growth, and enjoy the jungle vibe.
