Potted asparagus, due to improper maintenance, can easily cause the leaves to turn yellow. The reasons are as follows: Wenzhuxi is warm and humid, and winter should be sunny. In the winter, if it is not exposed to light for a long time, poor ventilation or cold can easily cause yellow foliage. At this point, it can be moved to a warm place with sunshine. The room temperature is maintained between 12 and 18°C. Watering can be properly controlled and it 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. For this reason, care should be taken to keep it in a clean environment. Bamboo should be fertile soil, if there is no long-term soil and fertilizer, nutrient supply in short supply, there will be yellow leaves. At this time, it is necessary to pour a diluted thin liquid fertilizer or compound fertilizer once a week, and water and loose soil in time, so that it can turn from yellow to green soon. Good fertilization too thick or end-of-age rotten fertilizer can easily lead to "rooting", causing 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 Xiyin Yin, avoid light. 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, and often spray water on the branches and leaves to increase the air humidity. When the damage is light, most of them can be restored. Wenzhu Xi wet, afraid of drought, avoid excessive moisture, blisters, the soil, water requirements are more stringent, to grasp the appropriate basin soil water is a key to daily maintenance of bamboo. 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 shoots gradually wither yellow and fallen leaves. The newly emerged buds withered in the middle. Three years or more of the vine plants showed a large number of falling flowers and falling seeds. Severe punishment can lead to the death of the whole plant. . 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 potted soil is wet, do not continue to water, it should be through the loose soil, change pots, clear the bottom hole, prompt the excess water to quickly spread out.
