How to propagate Epipremnum aureum through cutting
As a star indoor air-purifying plant, the propagation of Epipremnum aureum through cutting is a must-have skill for every plant enthusiast. With proper stem treatment and scientific environmental control, even beginners can easily master the propagation tips of Epipremnum aureum. This article will provide a detailed analysis of the two methods of soil culture and water culture propagation, along with real-shot illustrations demonstrating key steps.
Golden Rules for Propagating Epipremnum aureum through Cutting
Choosing the Best Propagation Period
April to August is the golden period for propagating Epipremnum aureum through cutting, with a stable daily average temperature between 20-28°C. In the northern regions, it can be extended to mid-September, while in the southern regions, room temperature should be maintained above 18°C in winter. Experimental data shows that the rooting speed in spring and summer is 40% faster than in autumn and winter.
Criteria for Choosing Stems
Select mature stems with 3-5 internodes, retaining the top pair of complete leaves. Pay attention to the prominent aerial root primordia at the internode sites, as these stems have a rooting rate of up to 95%. Use a sterilized scissor to cut at a 45-degree angle, which increases the cut area by 30% and is more beneficial for water absorption.

Soil Culture Substrate Preparation
Recommended formula: Perlite: Vermiculite: Peat = 1:1:2. The substrate needs to be sterilized with high-temperature steam and the humidity controlled at around 60%. Tests have shown that adding 5% charcoal powder can enhance antimicrobial properties and reduce the incidence of black rot disease.
Key Points for Water Culture Operation
Using a transparent container makes it easier to observe root development, with the water level covering 2-3 internodes being ideal. Add 2 drops of nutrient solution when changing water weekly, which results in a 22% higher survival rate for water-cultured seedlings when transplanted compared to direct soil culture.
Post-Propagation Care Strategy
After propagation, maintain scattered light and keep the air humidity above 70%. New roots can be seen after 15 days, and the first fertilization can be carried out after 30 days. Using this method, the success rate of propagating Epipremnum aureum at home can reach 90%, making it easy to achieve freedom with Epipremnum aureum.
