Aglaonema 'Silver Queen' Losing Variegation: Light, Temp, Water, or Food?

Why Colors Fade

Paradoxically, both too much and too little light cause variegation loss in Aglaonemas.

• Too much: Direct sun on leaves 1+ hours daily.
• Too little: >6 feet from window or window covered during day.

Other Factors

• Temps below 60°F.
• Hard/alkaline water.
• No fertilizer for a year—feed monthly at half strength.

Diagnosis

Your "medium indirect light" and no repotting for a year suggest fertilizer and water quality are top suspects. Adjust and monitor new growth.
