In horticulture a node is the spot where a leaf, and usually later a branch, emerges from the stem. If you examine a Maple stem it is pretty obvious where the nodes are, the sections in between nodes are known as internodes.four nodes,.. bonsai nodes and hormones must be different from other plants etc
Cuttings are generally severed just below a node as roots often emerge at that point.
BTW, cuttings can be softwood, semi-hardwood or hardwood depending upon the time of year they are taken. Some plants respond better to one method and some are able to be taken at more than one stage.
