"Green Dragon" Can Be Cultivated for a Long Time
Green Dragon, as a common evergreen houseplant, often troubles many gardening enthusiasts with sparse leaves and stagnant growth. In fact, this climber plant, known as the "Air Guardian," can regain its vigorous vitality as long as key cultivation techniques are mastered. This article will delve into four core cultivation methods to help you crack the growth code of Green Dragon.
Nutrient Matrix Optimization Plan
Soil Improvement Three-Step Method
Ordinary garden soil can become compacted over the years, leading to root suffocation. It is recommended to upgrade the matrix every spring: mix decomposed leaf soil, perlite, and vermiculite in a ratio of 2:1:1, and add 5% decomposed sheep manure as a base fertilizer. Retaining 1/3 of the original soil when repotting can reduce stress responses, and the new soil should be compacted to 2cm from the rim of the pot to leave space for watering.
Scientific Watering Advanced Guide
Intelligent Watering System
Use the "Three-Finger Test" to determine the watering time: when the second knuckle of the index finger inserted into the soil is dry, water it. Rice washing water should be sealed and fermented for 15 days, then diluted 1:20 to replace tap water. In winter, it is recommended to use warm water at 25°C, and add 3 drops of lemon juice to adjust the pH to the optimal absorption range of 6.0-6.5.
Precise Fertilizing Schedule
Nutrient Supply Plan
In the growing season (April-September), apply a balanced liquid fertilizer (N-P-K=20-20-20) every 10 days. During the yellow leaf stage, apply additional iron sulfate (0.2% solution) to correct iron deficiency. Foliar fertilizer is recommended to use potassium dihydrogen phosphate (1500 times dilution), and it should be sprayed with a nano atomizer in the early morning, which can thicken the leaves by 30%.

Form Management Secret Technique
Pruning to Promote Growth Rule
When the stem exceeds 30cm, cut it diagonally at a 45-degree angle 5cm from the top and apply plant ash to the cut to prevent infection. For propagation, use an 8cm branch with 2 aerial roots, and after rooting in water, transition to a perlite matrix. Regularly remove yellow leaves from the base and rotate the pot to achieve a立体爆盆 effect.
Through a four-dimensional cultivation system that includes soil improvement, intelligent watering, precise fertilizing, and scientific pruning, combined with wiping the leaves with beer (diluted 1:50) once a month, you can make the Green Dragon grow at an average rate of 3cm per week. These methods are also applicable to plants like hanging orchid and English ivy in the Araceae family, helping you create a vibrant green space.
