stemfeeding

Stemfeeding is a technique used in horticulture and plant propagation where a nutrient solution or hormone is applied directly to the vascular tissue of a plant stem. This method bypasses the traditional uptake through roots or leaves, allowing for targeted delivery of substances. It is often employed when root function is compromised, or when a rapid and precise application of a specific compound is desired.

The process typically involves making a small incision in the stem and inserting a tube or wick to facilitate the introduction of the liquid. This allows the solution to be absorbed into the xylem, the plant's water-conducting tissue, and transported throughout the plant. Stemfeeding can be used to deliver fertilizers, plant growth regulators, or even therapeutic agents to combat disease.

This technique can be particularly useful for plants that are difficult to establish or that are suffering from nutrient deficiencies. It is also utilized in research settings to study nutrient transport and plant physiology. While effective, stemfeeding requires careful execution to avoid damaging the plant's vascular system and introducing pathogens. The concentration and volume of the applied solution must be precisely controlled to prevent phytotoxicity.
