How to Care for Spatholobus Suberectus
Spatholobus suberectus, a climbing plant with both ornamental and medicinal value, is deeply favored by gardening enthusiasts for its unique blood-red sap. However, many novices often face growth obstacles due to improper management during the care process. This article will comprehensively analyze the key points of care from environmental control to shaping management.
Ⅰ. Core Elements of Environmental Management
Accurate Temperature and Humidity Control
The optimal growth temperature should remain stable within the range of 20-30℃, and it is necessary to maintain temperatures above 10℃ in winter to prevent frost damage. During the high-temperature periods of summer, misting in the morning and evening can effectively increase the humidity to 60%-75%.
Scientific Watering Strategy
In spring and autumn, maintain a watering frequency of 2 times/week, and water once in the morning and evening during summer. Use the bamboo stake test: insert it into the potting soil for 3 minutes and then pull it out; if the bamboo stake is moist, no additional watering is needed.
Ⅱ. Nutritional Supply System
Apply decomposed sheep dung organic fertilizer combined with NPK compound fertilizer every month, and water thoroughly after fertilization to promote nutrient penetration. Increase the application of phosphorus and potassium fertilizers before the blooming period, and use 0.2% phosphorus acid monopotassium spray on the leaves.
Ⅲ. Propagation and Shaping Techniques
Advanced Seed Propagation Guide
How to Care for Spatholobus Suberectus
Soak the seeds in 40℃ warm water for 6 hours before sowing in spring, and configure the substrate according to the ratio of peat: perlite = 3:1. Maintain a constant temperature of 25℃, and germination can occur within 14-20 days.
Stereoscopic Shaping System Construction
Choose a防腐木桩 (rot-resistant wooden stake) with a diameter of more than 5cm, and a recommended height of 2-2.5 meters. Use a spiral binding method, setting a fixed ring every 30cm, and leaving 20% of growth space.
Ⅳ. Pest and Disease Control System
Biological Control Solution
Hang yellow sticky insect boards (with a spacing of 1m/board) during the outbreak of aphids, and release ladybugs (10 heads/㎡). For chemical control, use a 10% imidacloprid solution diluted 2000 times, applied 7 days/interval for 3 consecutive times.
