The Translation: A node is the small bump, joint, or thick ring on a plant’s stem where leaves, roots, or branches emerge. It is the biological engine of the plant’s growth.
Use It In a Sentence: “If you want to grow a new plant from that vine, make sure you cut about an inch below the node.”
Why You Care: If you just snip off a pretty leaf and stick it in a glass of water, it will eventually rot and die. You must include a node on your cutting if you want it to grow new roots.
