Air Layering
This method is not very common but is highly effective. Air layering involves making a shallow cut in the stem and applying rooting hormone. Next, wrap the cut stem with damp sphagnum moss and secure it in place with plastic wrap. After about 3 months, roots will start to develop, and you can remove the section with the new root system and plant it in soil.
Conclusion
Whether you choose to propagate Gardenia triacantha DC. var. parvilimbis F.N.Williams through seeds, cuttings, or air layering, each method has its own advantages and disadvantages.
