How should geraniums be cared for to make them bloom more?

1. Overwatering or being exposed to rain, with long-term water accumulation in the pot, causes root rot, yellowing leaves, or leggy growth of the plant, all of which affect blooming.

2. Overfertilizing, especially applying too much nitrogen fertilizer, easily causes leggy stems and leaves, no blooming or sparse blooming, and poor flower quality. However, insufficient fertilization or no fertilization will also affect the plant's normal growth and blooming. Therefore, in early spring or early autumn, appropriately apply more phosphorus and potassium fertilizer.

3. Temperature too high or too low. If the indoor temperature in winter is above 20 C, combined with poor ventilation, the stems and leaves tend to grow leggy, affecting blooming the following year. However, if the overwintering temperature is below 0 C, it is also unfavorable for dormancy, and the plant may even be prone to frost damage, with leaf edges turning yellow and becoming soft. Geraniums are also relatively sensitive to temperature differences; if the temperature changes sharply, it will cause the flowers to drop. In summer, heat and direct strong light can easily cause sunburn on leaf edges, leading to poor growth or the dropping of flowers and leaves.

4. Too severe pinching and pruning. Having very few leaves for a long time will also delay the growth period, resulting in fewer flower buds and fewer blooms.

5. When cared for indoors in winter and spring, if there is insufficient light for a long time, the plant is prone to growing leggy and not blooming, and even flower buds that have already formed will shrivel and dry up due to insufficient light. Therefore, sufficient light should be provided in winter.
