root cutting

Root cutting refers to a piece of a plant's root used to propagate a new plant, such as with blackberries, horseradish, or oriental poppies. This method is a form of vegetative reproduction, which is asexual reproduction where a new plant grows from a part of the parent plant.12

In horticulture, cuttings are a vital propagation technique, and they can be derived from roots, stems, or leaves. Root cuttings are particularly useful for propagating trees that don't readily produce roots from stems, like willows and poplars. The ability of cuttings to form roots depends on various factors, including plant hormones, carbohydrates, and environmental conditions.34
