That claim is misleading.
Geranium plants can bloom for many months, but there is no single trick that will make them flower “almost continuously for over a year.” Blooming depends on growing conditions and the plant’s natural growth cycle.
To encourage the longest flowering period:
- Provide plenty of light. Geraniums bloom best with at least 6 hours of direct sunlight each day.
- Water appropriately. Let the top inch (2–3 cm) of soil dry before watering again. Avoid constantly soggy soil.
- Fertilize regularly. Use a balanced or bloom-boosting fertilizer every 2–4 weeks during the active growing season, following the product directions.
- Remove spent flowers (deadhead). Pinching off faded blooms encourages the plant to produce new flower stalks.
- Prune occasionally. Trimming leggy stems helps keep the plant compact and promotes new growth.
- Use well-draining soil and pots to prevent root rot.
In frost-free climates or indoors with enough light, geraniums may flower for much of the year. In regions with cold winters, flowering usually slows or stops during the darker, cooler months.
If you saw an article or video claiming that adding a particular household ingredient will make geraniums bloom continuously, it’s best to treat that claim skeptically. While some homemade remedies may provide small amounts of nutrients, there is no scientific evidence that any single ingredient can keep geraniums flowering almost nonstop for over a year.
