How to cultivate air root banyan bonsai
The aerial root banyan bonsai is very popular among gardening enthusiasts for its unique root shape, but to cultivate luxuriant artworks, scientific maintenance methods are needed. This article will systematically analyze the key points of cultivating air root banyan bonsai from soil configuration to daily management. The core maintenance technology matrix ratio and the soil of the improved air-root banyan bonsai need to take into account both air permeability and water retention. It is recommended to mix sandy soil and coal slag in a ratio of 3:1. This combination provides a porosity of 45% and ensures smooth root respiration. Adding 10% decomposed pine needles can increase the acidity of the substrate and better meet the growth requirements of banyan trees with pH 5.5 -6.5. Use bamboo sticks to loosen soil every month to prevent hardening and maintain soil activity. The smart irrigation system uses the "alternating dry and wet" method for watering, which is fully watered once every 3 days in summer and extended to 7-10 days in winter. It can be judged by the weight of the basin: when the weight is reduced by 30%, water needs to be replenished. Placing a ceramsite layer on the bottom of the basin can improve the drainage efficiency by 20%. Combined with morning and evening leaf spraying, it can maintain 80% air humidity and promote the development of air roots. During the growth period of the precision fertilization strategy, 3-5 grains of slow-release compound fertilizer (N-P-K=10 -10) are applied every month, combined with organic liquid fertilizer diluted 300 times once every season for irrigation. Key tips: Maintain ventilation for 24 hours after fertilization to avoid salt deposition. No fertilizer will be applied for the first 2 years of the new pile, and nutrient supplementation will be started after the roots are lignified. Advanced styling skills Air root guiding technology uses plastic pipes to guide the air roots and is wrapped with moss to maintain humidity. When the air root length reaches 15cm, it can be coiled. The best operation period is before the rainy season, when the tree sap flows vigorously and the shaping success rate is increased by 40%.
Through scientific soil management, precise water and fertilizer control, and professional modeling techniques, the aerial root banyan bonsai can maintain a healthy growth of 30cm per year. By regularly observing the status of plants and adjusting maintenance plans in a timely manner, ecological landscapes with artistic value can be cultivated.
