Yellow Leaves on chinese evergreen

chinese evergreen with yellow leaves

What's Happening

Chinese Evergreen (Aglaonema) exhibits yellow leaves through two distinct mechanisms. NATURAL SENESCENCE: The oldest basal leaf yellows over 2-4 weeks as the plant reallocates nutrients to new apical growth - this is healthy and expected in mature specimens. ROOT ROT/OVERWATERING: Multiple leaves yellow rapidly (within days), often accompanied by basal mushiness and accompanied by fungus gnats. The rhizomatous root system requires oxygen exchange between waterings; when soil remains saturated for 7+ days, anaerobic bacteria proliferate, compromising nutrient uptake and causing cellular breakdown visible as chlorosis.

How to Fix It

  1. 1

    Inspect pattern: Single oldest leaf = natural senescence; multiple leaves or rapid progression = problem

  2. 2

    Check soil moisture below surface: If wet despite 7+ days since watering = overwatering

  3. 3

    For natural senescence: Allow leaf to fully yellow, then snip at base with sterile scissors

  4. 4

    For overwatering: Unpot immediately, inspect roots for black/mushy tissue, trim affected roots with sterile scissors

  5. 5

    Repot in fresh chunky mix (50% potting soil, 30% perlite, 20% orchid bark) in appropriately sized pot

  6. 6

    Resume watering only when top 2-3 inches are bone-dry; use moisture meter for precision

How to Prevent It

Water only when top 2-3 inches of soil are completely dry; use well-draining aroid mix (40% perlite/bark minimum); ensure pot has drainage holes; maintain 60-80% humidity to reduce water needs; avoid automated watering systems that maintain constant moisture.
