Jasminum, also known as sweetgrass, is an ornamental plant with a strong fragrance. In spring, many jasminum begin to enter the growth period, but the leaves of some jasminum show the phenomenon of spring defoliation. This phenomenon not only affects the ornamental value of jasminum, but also may have an adverse effect on the growth of the plant. This article will analyze the reasons for the defoliation of jasminum in spring and provide corresponding care suggestions.
Reasons for the defoliation of jasminum in spring1. Temperature change: The temperature in spring gradually increases, and the temperature difference between day and night is relatively large, causing jasminum to adapt poorly and resulting in the phenomenon of spring defoliation of leaves.
2. Insufficient sunlight: The sun in spring is gradually getting stronger, but some jasminum growing environments have insufficient sunlight, causing the photosynthesis of the plant to weaken and resulting in the phenomenon of spring defoliation of leaves.
3. Soil moisture: Spring rainfall increases, resulting in higher soil moisture, which can easily lead to oxygen deficiency in the roots of jasminum and cause the phenomenon of spring defoliation of leaves.
4. Insufficient nutrients: Spring is the peak growth period of jasminum, and if the nutrient supply is insufficient, the plant's growth will be poor and the leaves will show the phenomenon of spring defoliation.
5. Diseases and insect pests: There are many diseases and insect pests in spring. If prevention and control are not timely, it may lead to the phenomenon of spring defoliation of jasminum leaves.
Care suggestions for defoliation of jasminum in spring1. Adjust temperature: The temperature in spring changes significantly, so it is necessary to adjust the indoor and outdoor temperature in a timely manner to maintain a suitable growth environment.
2. Increase sunlight appropriately: As sunlight in spring gradually strengthens, it is necessary to ensure that jasminum gets sufficient sunlight to promote photosynthesis.
3. Control soil moisture: There is more rain in spring, so it is important to pay attention to drainage and maintain appropriate soil moisture.
4. Fertilize in a timely manner: Spring is the peak growth period of jasminum, so it is necessary to apply organic and compound fertilizers in a timely manner to meet the plant's nutrient requirements.
5. Prevent and control diseases and insect pests: There are many diseases and insect pests in spring, so it is necessary to inspect the plants regularly and control diseases and insect pests in a timely manner.
Defoliation of jasminum in spring is a common phenomenon. Understanding its causes and taking corresponding care measures can help ensure the growth and ornamental value of jasminum. It is hoped that this article will be helpful to the majority of flower friends.
