Brown Spots

Our analysis of 61 verified rescue cases across 35 plant species shows exactly what causes brown spots and the most effective fixes.

Quick Summary

Brown spots on Pothos have multiple causes: 1) Overwatering/edema - most common, from waterlogged roots causing cell rupture, 2) Bacterial leaf spot - water-soaked spots with yellow halos from high humidity + wet leaves, 3) Sunburn - crispy brown patches from direct sun exposure, 4) Physical damage - soil splashing on leaves during repotting. Check if spots have yellow halos (bacterial) vs are uniformly brown (overwatering) vs are crispy (sunburn).

Most Effective Solutions

  1. 1 Improve air circulation with a small fan.
  2. 2 For overwatering: allow soil to dry, improve drainage, repot if root rot present
  3. 3 For bacterial spot: remove affected leaves, improve air circulation, avoid wetting foliage
