Yes, air layering is a very real and effective method of plant propagation.
Air layering is an age-old plant propagation technique where roots are encouraged to grow on a stem while it's still attached to the parent plant. Once sufficient roots have developed, the rooted stem is then severed and planted as a new, independent plant. This technique has been used for centuries, notably by the Chinese, and is a proven way to clone plants.
Here's a breakdown of why air layering is a legitimate propagation method:
-
Established History: As indicated by the references, air layering has a long and successful history, proving its effectiveness over time.
-
Scientific Basis: The process works by interrupting the flow of nutrients in the stem, causing a buildup of carbohydrates and hormones at the point of interruption. This stimulates the development of root primordia, which eventually grow into functional roots.
-
Practical Application: Gardeners and horticulturalists worldwide use air layering to propagate a wide variety of plants, including trees, shrubs, and houseplants, successfully.
-
High Success Rate: When performed correctly, air layering often has a higher success rate compared to other propagation methods like cuttings.
Why Choose Air Layering?
- Cloning: Air layering creates a genetic clone of the parent plant, preserving desirable traits.
- Larger Plants Quickly: It allows you to create a relatively large, mature plant more quickly than starting from seed or small cuttings.
- Difficult-to-Root Plants: It's often successful with plants that are difficult to root using other methods.
In conclusion, air layering is a genuine and valuable horticultural technique supported by historical evidence, scientific principles, and widespread practical application.
