That claim is almost certainly an exaggeration.
A peace lily (Peace lily) does not bloom for “10 years in a row” because of a single ingredient. Flowering depends on several factors, including:
- Bright, indirect light (the biggest factor)
- Consistent watering without waterlogging
- Moderate humidity
- Regular fertilization during the growing season
- A healthy, mature plant
Many viral posts recommend ingredients such as banana peels, coffee grounds, rice water, eggshells, or baking soda. While some of these may add small amounts of nutrients or organic matter, there is no scientific evidence that any one ingredient will keep a peace lily blooming continuously for years. In some cases, such as adding coffee grounds directly to the soil, they can even encourage mold or disrupt the soil if overused.
For the best chance of repeat blooms:
- Place the plant in bright, indirect sunlight.
- Water when the top inch (2–3 cm) of soil feels dry.
- Feed with a balanced, diluted houseplant fertilizer about once a month during spring and summer.
- Remove spent flowers and repot every few years if the plant becomes root-bound.
If you’re referring to a specific article or video that mentions “one ingredient,” tell me what the ingredient is, and I can explain whether it’s likely to help or whether the claim is misleading.
