Hashiri-ne

Hashiri-ne is a term that means "running root" in Japanese. It refers to a root that grows much longer in soil than other roots. It is also called "abare-ne" or "ramp root". Hashiri-ne is often seen in bonsai trees that are off-balance or stressed, and they try to extend their roots to the ground for stability and nourishment. Hashiri-ne can be used in bonsai to create interesting styles, such as the neagari or exposed root style, where the long roots are visible above the soil. However, hashiri-ne can also cause problems for bonsai, such as weakening the other roots, disrupting the balance of the tree, or making repotting difficult. Therefore, hashiri-ne should be trimmed or removed regularly to maintain the health and appearance of the bonsai.
