Asparagus officinalis yellow control method

Potted asparagus, due to improper maintenance, easy to cause yellowing of branches and leaves, the main reasons are the following: Wenzhuxi wet and warm environment, winter should be placed in sunny place. In winter, long-term exposure to light, poor ventilation, or cold places can cause yellow foliage. At this point, it can be moved to a sunny and warm place. The room temperature is maintained between 12°C and 18°C. Watering can be properly controlled. Asparagus can gradually return to normal. Wenzhu is afraid of smoke and dust. If toxic gases are encountered, the branches and leaves are susceptible to yellowing. Therefore, Wenzhu should pay attention to keeping it in a clean environment during conservation. Wenzhu Xi's fertile soil, if there is no change in soil and fertilizer for a long time, the supply of nutrients will be in short supply, and yellowing of branches and leaves will also occur. In this case, it is necessary to pour the diluted thin liquid fertilizer or composite fertilizer once a week, and water and loose soil in time, so that it can turn from yellow to green soon. If the fertilization is too thick or the fertilizer is not ripened, it will easily cause "burning roots", which will cause the leaves to dry and fall off. At this time, the pots need to be removed to remove the fertilizer, and the soil shall be poured with fresh water and then replaced with new soil. Wenzhu Xibanyin, avoid strong light environment. If it is kept in a place where it is exposed to direct sunlight during the summer season, it can easily cause yellow foliage. At this time, the pots should be moved to the shade, often spraying water on the branches and leaves, increasing the humidity of the air, and most of the plants that are damaged can be restored as they were. Wenzhu Xi wet, afraid of drought, but avoid excessive humidity, the soil and water requirements are more stringent, to grasp the appropriate basin soil water is a key to the daily maintenance of asparagus. If there is excessive watering in peacetime, resulting in long-term over-wet or accumulated water in pots, it will cause poor root growth, and then cause rot. The performance is that the upper part of the shoot is first leggy, then the yellow leaves of the leaf tip gradually become yellow and fall off. The newly emerged bud withered in the middle, and the vine plants more than three years old suffered from a large number of falling flowers and falling seeds. In severe cases, the whole plant died. When the watering is too little, the potted soil will be too dry, causing the leaves yellow to shoot, the branchlets to fall off, the body to dry, and the buds to fall. Therefore, the basin soil should always be in a wet alternate state. If it is found that the basin soil is too wet, and then continue to water, it should be through the loose soil, change pots, clear the bottom hole, prompting the excess water to quickly spread out.
