1. Soil alkalinization causes the leaves to be dullJasmine has very strict requirements for soil. It needs a slightly acidic soil with a pH value of less than 7 and dislikes alkaline soil. If the potted jasmine is not repotted for a long time, or fertilizer is not used to maintain the acidity of the soil, the soil will become alkaline, and it will not be able to provide iron, and the leaves will eventually become dull. Therefore, in order to solve the problem of leaves not being shiny, you need to increase the pH value of the soil. Now is the peak flowering season. Changing pots and soil will affect flowering. It is recommended to use ferrous sulfate to increase soil acidity. After the flowers wither, dilute the mixture in a ratio of 1000 ml of water: 1 ml of ferrous sulfate, and repeat this process every 15 days until the leaves become shiny. 2. Too little light causes the leaves to be dullJasmine is a flower plant with a strong sun-tropism. Only a growing environment with plenty of sunlight can maintain normal growth of the plant. If it is placed in a dark place indoors for a long time, it will hinder the photosynthesis of the leaves. Over time, the leaves will become dull and grow too tall. Therefore, if you want to solve the problem of the leaves not being shiny, you need to place it in a growing environment with sufficient sunlight. After a period of exposure, the leaves will gradually regain their green color. Where to put it?Place it on a south-facing balcony indoors, or in a sunny location outdoors. In addition, when there is plenty of sunlight, remember to water it immediately after the soil surface is dry, and choose to water it in the morning or evening when the soil is not hot. 3. Too little nutrition causes the leaves to be dullJasmine likes fertile soil environment, and now it has entered its peak flowering period, it needs to consume more nutrients. If the plant is not maintained and fertilized for a long time, it will enter a state of poor growth. In the long run, the leaves will become dull, and in severe cases, it will not bloom. Therefore, in order to solve the problem of dull leaves, reasonable fertilization management must be carried out to promote plant growth and maintain the leaves' bright green color. How to fertilize?The temperature is too high in summer, and improper fertilization can easily cause root burn. It is recommended to fertilize at night, using nutrient-rich cake fertilizer water, and dilute it before use. It needs to be done every 20 days. |
