Why Your Pothos Has Leaf Spots and How to Fix It

Diagnosing the Problem

Your pothos (Epipremnum aureum) shows vigorous new growth at the base and vine tips, but the middle leaves develop brown or yellow spots. The clue is in the spacing: leaves are farther apart than the ideal 1 inch per node. This indicates insufficient light.

Low Light = Weak Leaves = Disease Susceptibility

In low light, pothos produces thin, soft leaves with less waxy cuticle and reduced cellular defenses. These leaves are prime targets for fungal pathogens (commonly Phyllosticta, Colletotrichum, or Cercospora species) that cause leaf spot. The spots typically appear on older, interior leaves first because they're the most shaded and physiologically oldest.

Immediate Actions

1. Remove affected leaves. Snip off every spotted leaf at the petiole. This removes inoculum and improves air flow.
2. Increase light exposure. Move the plant to a brighter spot—east or west window, or a few feet from a south window. Avoid direct hot sun.
3. Adjust watering. Bottom watering is fine, but let the top inch of soil dry between waterings. Wet leaves + low light = fungal heaven.

Long-Term Prevention

• Rotate the plant weekly for even light distribution.
• Wipe leaves occasionally with a damp cloth to remove dust.
• Fertilize lightly during active growth (spring–summer) with a balanced houseplant fertilizer.

With better light and prompt leaf removal, new growth will be tighter, stronger, and resistant to spotting.
