avläggs

Avläggs is a term used in horticulture, particularly in Swedish practice, to refer to plant propagules produced by a layering method. Layering refers to vegetative propagation in which a portion of a still-attached shoot develops roots while remaining connected to the parent plant, after which the new plant can be separated and grown independently. The concept is closely related to the general practice of layering in plant propagation, and it is used to preserve desirable traits of the parent plant.

There are several forms of layering. In soil layering, a flexible stem is bent to the ground and a section is partially buried and anchored in place, allowing roots to form along the buried portion. In air layering, a section of stem is girdled and wrapped with moist medium or moss to induce root development before the shoot is detached from the parent. Tip layering involves placing the tip of a stem in contact with soil to encourage rooting. Each method aims to produce a rooted, independent plant while the original shoots continue to supply nutrients during root formation.

Process and timing can vary by species, but common steps include selecting a healthy, vigorous shoot; preparing the rooting site or wrapping medium; maintaining consistent moisture; and waiting for roots to develop over weeks to months. Once roots are well established, the new plant is separated from the parent and transplanted.

Avläggs are used for many fruit trees, shrubs, and ornamentals, especially when species root poorly from cuttings or when identical clones of a selected cultivar are desired. They offer a way to multiply plants with preserved characteristics, though success rates can be variable and require appropriate care. See also: layering in plant propagation.
