2. Avoid watering too much or too little. Although asparagus likes to be wet, it should not be too wet. If the basin soil is too wet and the drainage is not smooth, the roots will rot. Too little or no watering will cause the leaves to fall off because of the large evaporation and small absorption of asparagus. Usually, it is necessary to properly control the amount of watering, so that it will be transparent if it is not done, and the basin soil will always be wet.
3. Apply dilute liquid fertilizer 1-2 times a month during the growing period, and avoid applying thick fertilizer, otherwise the branches and leaves will turn yellow. After plant shaping, the amount of fertilization can be reduced to avoid affecting the appearance of the plant, and attention should be paid to proper pruning and shaping.
3. Prevent the pollution of harmful gases. Asparagus likes a clean and ventilated environment. If it is stimulated by harmful gases such as smoke, gas and pesticides, its leaves will turn yellow, curl and even die.
Extended data:
Asparagus leaves are beautiful, elegant and exquisite, and potted plants are often placed on bookshelves, desks and coffee tables to beautify the living room. However, due to its rapid growth, small and beautiful appearance is often not lasting, so it must be shaped or shaped, and its methods are as follows:
1. Pot control method: The size ratio of flowerpot to plant should be 1: 3, which can limit the growth of root system and keep the plant size unchanged.
2. Using the phototaxis of asparagus: rotating the direction of flowerpot in time can correct the growth shape of branches and leaves and keep the plant type unchanged.
3. Remove the growing point: When the new bud grows to 2-3 cm, remove the growing point, which can promote the regeneration of branches and leaves on the stem, prevent vines from growing, and make the branches and leaves flat and full.
4. Object shading method: that is, press the branches and leaves with cardboard or shade the sun, so that when the branches and leaves grow, they will rotate or bend to shade when they meet objects, thus achieving the purpose of modeling.
The shaping of asparagus must be combined with fertilizer control and water control. That is, at room temperature 15- 18℃, water once a week to keep the soil moist. Not fertilized or less fertilized.
