If you mean this as a gardening claim: a peace lily cannot be guaranteed to bloom for 10 years in a row because of one ingredient alone. Long-lasting flowering depends on several factors: bright indirect light, proper watering, humidity, temperature, and regular feeding.
A commonly recommended “one ingredient” for encouraging blooms is a balanced fertilizer (especially one with adequate phosphorus), but over-fertilizing can harm the plant. A healthier approach is:
- Keep soil lightly moist but not waterlogged.
- Place it in bright, indirect light.
- Feed during the growing season with a diluted houseplant fertilizer every few weeks.
- Repot when root-bound.
A mature, well-cared-for peace lily can live for many years and produce flowers repeatedly, but there is no single ingredient that guarantees a decade of continuous blooms.
