Hibiscus rosa-sinensis, scientifically known as Hibiscus syriacus, has large and charming flowers with spreading and soft petals. In many cultures, it is regarded as a symbol of auspiciousness, prosperity and beauty.
Hibiscus rosa-sinensis likes a warm, humid and sunny environment. If your home can provide such conditions, it will become a beautiful sight. Most family balconies or windowsills can meet the light requirements of Hibiscus rosa-sinensis during sunny periods. However, it should be noted that during the hot summer, direct strong light should be avoided to prevent burning of the leaves and flowers.
In terms of temperature, Hibiscus rosa-sinensis is not cold-resistant. The indoor temperature in winter is best kept above 10°C; otherwise, it is prone to freezing damage. At the same time, it also has certain requirements for humidity. A dry environment may cause the leaves to turn yellow and dry. The air humidity can be increased by frequently spraying water around the plants.
Furthermore, Hibiscus rosa-sinensis is not too demanding on the soil, but loose, fertile and well-drained acidic soil is more conducive to its growth.
Next, let's take a look at the reasons why the flower buds of Hibiscus rosa-sinensis always fall off. One common reason is insufficient light. Hibiscus rosa-sinensis is a positive plant. If it is in an environment with insufficient light for a long time, it will affect photosynthesis, resulting in insufficient nutrient supply and thus causing the flower buds to fall off. Improper watering is also an important factor causing the flower buds to fall off. Excessive watering can easily cause water accumulation at the roots, causing root rot, affecting nutrient absorption and leading to the falling of flower buds; while too little watering and water shortage of the plants will also affect the growth and development of the flower buds.
Unbalanced fertilization also has an impact. Hibiscus rosa-sinensis needs sufficient nutrients to flower. If fertilization is insufficient, especially the lack of phosphorus and potassium fertilizers, the flower buds may fall off due to nutrient deficiency. But if fertilization is excessive, especially too much nitrogen fertilizer, it will cause excessive growth of branches and leaves, competing for nutrients with the flower buds and also causing the flower buds to fall off.
In addition, the invasion of pests and diseases cannot be ignored. For example, pests such as aphids and red spiders will suck the sap of the plants, affecting the normal growth of the plants and causing the flower buds to fall off. Also, sudden changes in the environment, such as a sudden drop in temperature or moving the position, may cause stress to Hibiscus rosa-sinensis, resulting in the phenomenon of flower bud drop.
In conclusion, Hibiscus rosa-sinensis is suitable for home cultivation. As long as we can provide it with a suitable growth environment and take good care of it, it can grow healthily. For the problem of flower bud drop, as long as we identify the cause and take appropriate measures, it can be effectively solved.
