What is causing the leaves of the hibiscus flower to turn yellow?
This is a brief experience in green plant maintenance about why the leaves of the hibiscus flower turn yellow and the correct watering method for hibiscus, with the following details:
The yellowing of hibiscus leaves is caused by improper maintenance. Hibiscus is a common flower often used in greening, such as roadside green belts, urban residential areas, etc. It is also suitable for home cultivation and can be planted in pots and placed on the阳台. So, why do the leaves of the hibiscus turn yellow?
I. Improper watering
Hibiscus is somewhat drought-tolerant and does not like too much water. There should be some moisture in the soil every day, which means we need to keep the soil slightly moist when growing hibiscus. If there is not enough water in the soil, the leaves of the hibiscus cannot absorb moisture, and they will turn yellow and look listless. If too much water is poured at once, causing积水 in the soil and poor ventilation, the roots of the hibiscus are prone to rot, which can then lead to yellow leaves. When watering hibiscus, pay attention to the amount and water only when the soil is dry. For hibiscus grown outdoors, drainage should be ensured during the rainy season.
II. Over-fertilization
Hibiscus needs to be fertilized during its growing period, especially before the blooming season, as flowering requires a lot of nutrients. Therefore, it is necessary to fertilize appropriately during the bud differentiation stage to promote the differentiation of hibiscus flower buds. If the plant lacks nutrients, its leaves are prone to yellowing. However, over-fertilization should be avoided as it can cause root burn, leading to yellow leaves as well. When over-fertilization occurs, water the plant thoroughly to dilute the fertilizer in the soil, or change the pot if necessary.
III. Diseases and pests
Hibiscus is prone to diseases and pests during the spring, summer, and autumn seasons, especially for weaker young plants. When affected by diseases or pests, the leaves of hibiscus turn yellow, and the plant becomes increasingly weak, which may also affect blooming later on. To prevent and control diseases and pests, it is important to observe the plant growth during the growing period, address early signs of diseases or pests manually or with chemicals. Also, pay attention to the surrounding plants of the hibiscus, and if any diseases or pests are found, they should be treated promptly to prevent transmission.
The flowers of hibiscus resemble peonies and also look like hibiscus syriacus. Its flowers look delicate, like a little girl. Hibiscus is suitable for planting in courtyards or on balconies, with moderate sunlight and sufficient moisture in the soil to grow well.
