1, illumination: Asparagus prefers semi-shady ventilation environment. Asparagus cultivation should not be exposed to the hot sun. In hot season, it should be placed in a cool and ventilated place. However, it should be noted that the environment where asparagus is placed should not be too dark. If there is insufficient light, the stems of plants and animals will grow long and weak. Therefore, in spring and autumn, asparagus should be properly placed outdoors to receive sunlight.
2. Pruning: As asparagus is a climbing plant, if it is allowed to grow naturally and its shape is not good, potted plants, especially bonsai, need pruning and shaping. There are two purposes: one is to prevent overgrowth and avoid plant deformation; Secondly, promote the budding of the hidden buds in the appropriate parts and grow into the required shape. After pruning, the watering amount should be reduced appropriately, and the pot soil should not be too wet, otherwise the pruning will fail.
3. Fertilization: Fertilization should be measured. Too fat is easy to grow wildly and destroy the shape; Without fertilizer, plants will be thin and the branches and leaves will not flourish.
Fertilizing asparagus should be thin and fat, not thick, otherwise it will cause yellow leaves. Generally, you can choose to apply decomposed dilute liquid fertilizer once a month. It can also be decided according to the growth of.
4. Soil: The pot soil of asparagus should be fertile sandy loam, which should be warm and humid, rich in rotten branches and well drained. Generally, it can be prepared with 4 parts of garden soil, 2 parts of humus soil, 2 parts of compost soil and 65,438+0 parts of sand, and the soil should be changed and fertilized regularly. If the soil is used as a bonsai, it should not be too loose to avoid instability of asparagus. In addition, according to the plant size and the specifications of the pot, the pot soil should be changed every 1-2 years.
In addition to the above, asparagus should be placed in a clean and well-ventilated environment to avoid harmful gases such as smoke, gas, pesticides and mercury gas that may be released by decorative materials from adversely affecting plants. Also avoid storms.
