What is Plant Layering

Layering plants is a method of propagating plants where new roots form on the stems while they are still attached to the parent plant. After the stem has rooted, it is detached and becomes a new plant of its own.

The rooted stem is then detached, transplanted, and becomes a separate plant on its own roots once enough root development has taken place.

Some plant species utilize layering as a natural means of reproduction. This is seen in black raspberries and trailing blackberries through tip layering, in the runners of strawberries and the stolons of Bermuda grass.

Reasons for Layering

Layering is a way to propagate a variety of plant species that are difficult or impossible to root from cuttings.

There are several possible explanations for this increased success, including maintaining physical attachment of the stem to the mother plant and therefore continuously supplied with water and minerals through the intact xylem. Another explanation may be due to an increased accumulation of photosynthates and hormones in the rooting area of the stem. This happens because bent stems stop the translocation of carbohydrates, auxins and other growth factors.

There are numerous different ways to layer plants. Keep an eye out for future posts where you can find some more details on these methods.
