Oikomi
Oikomi is a Japanese term that means "pushing in" or "moving in" in relation to bonsai. It is a method of trimming that is aimed at cutting back close to a bud in the root parts and thereby moving the next bud closer to the trunk. This technique helps to keep the branches thin and compact, as they tend to thicken over time. Oikomi is performed at different times depending on the kind of trees, but it usually occurs in spring or autumn.
