Answer: Lingxiao is a deciduous woody vine flower belonging to the genus Bignoniaceae. It is also known as Lingxiao flower, bigster, and wall flower. It is also called Lingxiao in ancient books. Use the air roots to cling to other objects and extend upward. It has strong adaptability, likes moisture, is drought-tolerant, and can grow well in slightly acidic, neutral to slightly alkaline soils that are well-drained and rich in organic matter.
Planting Lingxiao can be done in spring and autumn, while American Lingxiao and other species should be planted in spring. Mature trees must be transplanted with soil.
For Lingxiao planted in the open field, the tree hole should be appropriately expanded and dug deeply to improve the soil conditions and lay a better foundation for future luxuriant growth. After digging the tree hole deeply, it is easier to plant the plant deeper during planting. If too much soil is filled after deep planting, the early growth of Lingxiao will not be luxuriant. If there is too little filling to maintain the original depth of the plant, a low-lying tree hole will be formed, which is prone to water accumulation. For this reason, after digging the tree hole deeply, it should be backfilled before planting, and then planting should be done after the backfill reaches a certain depth. When backfilling, topsoil with high fertilizer content and good soil structure should be filled into the bottom of the hole. It is best to mix decomposed organic fertilizer into the backfill soil, which can not only be used as base fertilizer, but also improve the base soil, which is beneficial to the growth and development of plants.
After planting, year-round fertilizer and water management is mainly carried out in spring. After Lingxiao germinates, a slightly thicker liquid fertilizer should be applied once. The type of fertilizer should be chicken and duck manure or human feces that is rich in phosphorus and potassium. After fertilizing, water should be poured once to promote the growth of branches and leaves of Lingxiao and the differentiation and development of flower buds. After the leaves fall in autumn, the soil in the rhizosphere of the plant can be dug once, and the digging can be combined with the application of decomposed manure every 2 to 3 years.
Fertilizer and water management of potted Lingxiao. During the growth period, top dressing should be carried out according to seasonal changes and plant growth. Top dressing can be applied once before and after flowering. Combined with fertilization, water it in time to maintain the pot soil. Moisturizing and nutritious. When overwintering in winter, you should prevent the pot soil from containing too much water and pay attention to keeping warm and anti-freezing to protect the root system from freezing damage. In order to achieve the above purpose, the potted Lingxiao that can be moved is generally buried in the soil in late October, and the pot surface is covered with some fallen leaves or grass, or the container is wrapped with grass or soil culture to protect it. In mid-to-late April of the next year, dig out the pot from the soil or remove the protective material, and perform pruning, loosening and fertilizing.
