The Cultivation Method and Precautions of Polyscias fruticosa
Polyscias fruticosa is favored by horticulture enthusiasts for its unique spiral leaf arrangement and robust vitality. As a typical succulent plant, its maintenance needs to consider both drought resistance and growth patterns. This article will systematically analyze the scientific cultivation methods of Polyscias fruticosa from substrate proportion to environmental regulation.
Environmental Regulation for Cultivating Polyscias fruticosa
Soil Substrate Proportion Scheme
Sandy soil is the best choice, it is recommended to use a golden ratio of 60% coarse river sand + 30% akadama soil + 10% decomposed leaf soil, which can ensure drainage and provide necessary nutrients. It is necessary to repot and change the soil every spring to prevent soil compaction.
Light Intensity and Cycle Management
In the growing period (April to October), full sun care is required, and 30% shading is needed at noon in summer. In the dormant period (November to March), maintain 5 hours of scattered light per day, and it is recommended to use supplementary lights to prevent etiolation and deformation.
Temperature Adaptability Analysis
Tolerance range is -2°C to 45°C, with an ideal growth temperature zone of 15-28°C. It needs to be moved indoors when the temperature is below 5°C in winter to avoid frost causing cell damage.
Key Points of Nutrient Management for Polyscias fruticosa
Precise Irrigation Techniques
Adopt the principle of "thoroughly wetting after completely drying", and use the bamboo stake insertion method to detect soil moisture. Irrigate every 15 days in spring and autumn, every 7 days in summer (in the evening), and stop watering in winter. Pay attention to slowly pouring water along the pot wall to avoid water accumulation in the leaf heart causing rot.
Scientific Fertilization Strategy
Base fertilizer is recommended to use bone meal + wood ash (mixed in a ratio of 3:1). Top-dress with diluted earthworm dung liquid (diluted 2000 times), applied once in spring and autumn. Apply phosphorus and potassium fertilizer during the budding period, and use banana peel compost liquid fertilizer to supplement trace elements.

Disease Prevention Measures
Spray garlic extract solution monthly to prevent fungal diseases, and immediately treat scale insects with 75% alcohol locally. Strengthen ventilation during the rainy season and spread diatomaceous earth to form a physical protective layer.
Propagation Techniques
Side bud division should be carried out in spring, and the cut surface needs to be dried for 3 days before planting. For seed propagation, maintain a constant temperature of 25°C and use potassium permanganate solution to soak seeds to improve germination rate.
Through systematic environmental regulation and precise care, Polyscias fruticosa can maintain its perfect spiral shape. It is recommended to establish a care log, record watering and fertilizing times, and adjust management plans dynamically according to the plant's condition to cultivate astonishing geometric美学 plants.
