Yellow New Growth on Peace Lilies: Root Rot or Nutrient Issue?

Yellow, sickly new leaves on peace lilies often indicate root problems. Check roots: brown, mushy roots mean rot from overwatering. Trim affected roots, let the root ball air-dry a few hours, then repot in fresh, well-draining mix.

Other Causes

• Fungus gnats: their larvae damage roots. Use yellow sticky traps and allow soil to dry more between waterings.
• Nutrient deficiency: feed with half-strength balanced fertilizer monthly.
• Pot-bound: if roots circle tightly, move up one pot size.

Repot annually in spring. With corrected watering and drainage, new growth should emerge green and strong.
