Tips on how to raise asparagus
Amomium has become a popular choice for home green plants because of its slender and elegant branches and leaves, but many novices often cause the yellow leaves to wither due to improper maintenance. This article will systematically analyze the complete maintenance system of asparagus from soil configuration to four-season management, so that your asparagus always maintains a green and straight posture. Analysis of core maintenance points Scientific soil matching and selection of high-quality soil is the foundation for the growth of asparagus. It is recommended to use a gold ratio of peat soil: perlite: legus soil =4:3:3, and the pH value is controlled between 5.5 and 6.5. Add 5% pine needle soil to enhance acidity when changing pots every spring. The diameter of the pot should be 3- 5 cm larger than the diameter of the root system. It is recommended to use a veg-fired pottery pot with a 3cm-thick ceramsite drainage layer. The law of balance of light and shadow requires 4 hours of scattered light every day, and light can be filtered through gauze curtains. In summer, you need to stay more than 1.5 meters away from the western sun window, and in winter, you can move it to 0.8 meters away from the south window. If the distance between new leaves is found to exceed 3 cm, it means that there is insufficient light and light needs to be replenished. The water management cycle adopts the "three-finger test method": insert your fingers into the second joint of the soil, and water is needed when it is dry. Maintain a 5-day watering cycle in spring and autumn, shorten it to 3 days in summer and extend it to 10 days in winter. Wipe the leaves with beer diluent 1:50 every month to make the leaves brighter. Temperature control plan The best growth of asparagus is at 18-24 ° C and can be maintained by the following methods: spray every morning and evening when high temperatures in summer; in winter, use a set basin method (the outer basin is filled with foam particles) to keep warm. Pay attention to avoid the temperature difference between day and night exceeding 10℃. Nutrient replenishment strategy Apply nitrogen, phosphorus and potassium balanced liquid fertilizers (diluted to 1/2 of the standard concentration) every month during the growth period, and stop fertilization during the dormant period. It is recommended to apply fertilizer 2 hours after watering, and the use of EM inoculant can increase the fertilizer efficiency by 30%.
Through these five dimensions of scientific maintenance, combined with regular pruning of dense branches (retaining 3-5 branches of the main trunk), your asparagus can not only avoid the trouble of yellow leaves, but also create a well-layered ornamental shape. Remember that stability is more important than radicalization, and the most important thing to maintain Wenzhu lies in persistent and careful observation.
