Layering Flashcards
A method of layering that involves girdling a stem above the ground and covering it in moist media before wrapping it in plastic and sealing it
One of the oldest forms of layering; invented by ancient Chinese for camellias
Air layering
A method of layering that involves laying an entire branch horizontally on the surface of the soil and that yields numerous daughter plants rather than just one
a.k.a. French layering
Compound layering
A method of layering that combines division and layering techniques and in which an entire plant is buried in a hole until only the tips are exposed; only works on a limited number of shrub species
Works well for dwarf rhodos, some conifers, boxwood and barberries
Drop layering
Term used to describe the rooted stem produced by layering
Layer
A form of rooting cuttings in which adventitious roots are initiated on a stem while it is still attached to a plant
Layering
A method of layering in which shoots are cut back to the ground and soil or other media is mounded around them to stimulate roots to develop at their bases
a.k.a. “Stool” layering
Only form of layering still used commercially
Mound layering
A method of layering for plants with long, flexible shoots that involves alternately covering and uncovering sections of a horizontal shoot laid on the surface of the soil; produces multiple daughter plants
Serpentine layering
A method of layering that involves bending an intact shoot to the ground to cause adventitious roots to form and that yields one daughter plant
Process:
Use flexible, one-year old branch
• Bend and peg down ~6-9” from tip
• Cover base
Simple layering
The resulting rooted shoot from mound layering
Stool shoot
A method of layering that naturally occurs in some Rubus species [KR: where the distal end of a shoot is buried instead of 6-8” back from the distal end].
Tip layering
A form of mound layering that’s done in a container; helpful for small spaces.
Containerized layering
Plant is placed at an angle. A trench or trough is dug next to the plant and then the entire plant is pegged down into the trench and covered with a few inches of soil/media. Each branch will start to form adventitious roots and become a new plant.
Trench layering
When will layers be ready to sever from the parent plant?
If layered in later winter to early spring = ready by fall
If layered in summer or fall = ready by next spring
Where is the best place to “layer” using simple or air layering
6-9” back from the tip (no more than 12”)
