Reviving a 19-Year-Old Pothos After Repotting and Overwatering

A cherished 19-year-old pothos ("Annabelle") declined after being moved during carpet cleaning. Leaves wilted; watering didn't help. A cracked pot was discovered, then replaced with a larger pot and fresh Miracle-Gro soil. Soil had strong ammonia smell (indicating anaerobic conditions from overwatering). Dead leaves/stems were trimmed. Plant revived for three days then declined again with yellowing, browning, wilting leaves. Owner experiences bitter taste when touching plant.

Core Issues

Watering and fertilizing problems. The ammonia smell confirms prolonged waterlogging. The bitter taste may indicate fungal metabolites or chemical residue.

Correct Watering Method

Water by weight: feel pot heaviness after thorough watering, then wait until significantly lighter and soil surface is pale before watering again. Frequency varies by plant, light, pot size—daily to monthly. Death comes from frequency errors, not volume.

Fertilizer

Buy quality indoor fertilizer (e.g., Miracle-Gro Indoor) and follow directions. Fertilize monthly.

With corrected watering, Annabelle should recover quickly.
