Juurtumistuki

Juurtumistuki is a Finnish term meaning support for rooting. In horticulture, it refers to the measures taken to promote the formation and growth of roots in plant propagation. It is especially relevant for cuttings, seedlings, and transplants that must establish in a new substrate. The concept appears in nursery literature and practical cultivation, and the term is commonly used by Finnish growers to describe the care needed to develop a healthy root system.

Juurtumistuki includes selecting the right rooting medium, providing adequate moisture and aeration, and using temperature control such as bottom heat. It commonly involves maintaining high humidity, good air circulation, and light conditions appropriate for the species. In propagation of cuttings, techniques such as using fresh cutting material, maintaining proper cutting length, applying rooting hormones (auxins), and avoiding desiccation are part of juurtumistuki. After rooting, gradually adapting to drier conditions helps establish a sturdier root system.

In forestry or landscape planting, juurtumistuki may encompass measures that reduce stress on young plants during establishment, including mulching, shielding from extreme temperatures, and irrigation management. The term is therefore used as a technical description of practices rather than a formal policy program, and its effectiveness depends on species, season, and growing conditions. In English-language contexts it is often translated as rooting support or rooting aid.
