Why the branches and leaves of asparagus turn yellow easily

There are several reasons for the yellowing of asparagus branches and leaves:

(1)Too much light. Wenzhu likes half shade and avoids strong light. If it is placed in direct sunlight in summer, it is easy to cause branches and leaves to wither. At this time, the flowerpot should be moved to a cool place; often spray water on the branches and leaves to increase the humidity of the air, and most of the light victims can be restored to their original state.

(2)Watering is inappropriate. Wenzhu likes moisture but fears waterlogging. More water makes the roots rot; less water makes them dry. Therefore, rotten roots should be controlled by watering and often loosening soil; yellow and dry leaves should be watered first, and then gradually increased, while spraying water on branches and leaves.

(3)Nutrient deficiency. Wenzhu should be fertile soil, if there is no long-term change of soil and fertilizer, nutrient supply exceeds demand, there will be yellow branches and leaves phenomenon. At this time, it is necessary to irrigate thin liquid fertilizer or compound fertilizer once a week, and water and loosen soil in time.

(4)Improper fertilization. If topdressing is too thick or the end of the fertilizer is decomposed, it is easy to cause "burning roots", resulting in leaves drying and falling off. At this time, it is necessary to remove fertilizer from the basin, rinse the soil with clean water, and then replace it with new culture soil.

(5)Winter is poorly managed. Wenzhu likes warmth and should be placed in the sun in winter. So when it is placed in a place where there is no light, poor ventilation or cold, it is easy to cause the branches and leaves to wither. Move it to a warm place with sunshine, keep the room temperature at 12~18 degrees Celsius, and control watering properly, which can gradually return to normal.

(6)Poison. Wenzhu afraid of smoke, if encountered toxic gases, the branches and leaves easy to yellow. They should be kept in a clean environment. In winter, the room where the furnace is made should often be sprayed with warm water close to the room temperature to prevent poisoning due to coal dust covering the branches and leaves.

In addition, the plant is too large, the flowerpot is too small or damaged by pests such as scale insects, which can also cause yellowing of branches and leaves, so it should be changed in time and prevented.

Potted asparagus, such as improper maintenance, often yellow branches and leaves phenomenon. The causes of yellowing of asparagus branches and leaves and their prevention measures are summarized as follows: (1) excessive light. Wenzhu likes half yin and half yang, avoid direct sunlight, otherwise it will cause yellowing of branches and leaves. So shade the asparagus. (2)Watering is inappropriate. Wenzhu likes wet but afraid of waterlogging, so it should be cultivated in sandy soil with ventilation and water seepage. Watering should be appropriate, too much will rot the roots, too little will make the leaves yellow. When the weather is hot and dry, spray water on the branches and leaves every day to increase the humidity of the environment and compensate for the evaporation of water in the branches and leaves. (3)Nutrient deficiency. Potted asparagus, if changed pot for many years, will cause soil nutrient deficiency. If you only irrigate water at ordinary times and do not irrigate fertilizer, it will also cause insufficient nutrition. Potted asparagus, should be watered once a week thin decomposed liquid fertilizer, and timely watering and loosening. (4)Improper fertilization. If too thick or non-decomposed fertilizer is applied, it will hurt the roots and make the leaves yellow and fall off. Water should be used to wash basin soil, dilute fertilizer concentration, or immediately change the soil method to save. (5)Winter management is bad. Wenzhu likes warmth and is afraid of cold. In winter, it should be placed in a warm and sunny place indoors. The room temperature should be kept above 8-12℃. For a long time, it will turn yellow at room temperature below 8℃. Water must also be controlled. (6)Smoke pollution. Bamboo afraid of smoke and toxic gases, should be placed in the air circulation, to avoid pollution. Also often spray water to the branches and leaves to wash off dust.
