A node is the point on a plant stem from which a leaf grows, from which an aerial root emerges, or from which a lateral branch develops. On most houseplants, nodes are visible as slightly swollen joints on the stem, the point where the leaf stalk (petiole) meets the main stem, or as small bumps on bare stems where leaves have been removed. Nodes matter for propagation because they contain meristematic tissue: specialised cells that can differentiate into new roots, shoots, or leaves. A cutting without a node cannot produce roots or new growth and will eventually die. A cutting with at least one node has everything it needs to become a new plant.
How to Identify a Node
On a leafy stem, the node is the point where each leaf attaches to the stem. This is easy to see while the leaf is present. On a bare stem (from which leaves have been removed), the node is visible as a slight thickening of the stem or as a small scar where the leaf was attached. On many aroids (Monsteras, Philodendrons, Pothos), nodes also produce aerial roots, either as small brown nubs or longer aerial roots that extend from the stem. These aerial root nodes are particularly valuable for propagation because the root-producing cells are already active.
The space between two nodes is called an internode. For propagation, internodes are essentially inert: cutting between nodes leaves no meristematic tissue to produce roots or new shoots from. This is why the guidance is always to cut just below a node rather than in the middle of the stem.
Why Cuttings Need a Node to Root
When a cutting is placed in water or propagation medium, the meristematic cells at the node are stimulated by the presence of auxin (a growth hormone that accumulates at cut points) and the moisture contact to differentiate into root cells. This process is specifically triggered at the node; it does not occur in stem tissue between nodes. This is why a cutting with only internode tissue (no nodes) placed in water will stay clean, not rot, and produce nothing: there are no cells capable of forming roots present.
For species that produce aerial roots readily (Monstera, Pothos, Epipremnum), including a node that already has an aerial root stub greatly speeds propagation: the root cells are already partially activated and simply continue developing into full roots when placed in water or soil.
How Many Nodes Does a Propagation Cutting Need?
A cutting needs a minimum of one node to root. However, cuttings with two to three nodes are more reliable because they have more sites for root development and more leaf area for photosynthesis (which supports the energy demand of root production). For water propagation, one node submerged in water and one or two leaves above the waterline is the typical minimum effective cutting. For soil propagation, at least one node buried in the propagation mix with one or two leaves above is similarly the minimum. See our guide on propagating directly in soil for the soil propagation process.
Node Cuttings vs Tip Cuttings
A tip cutting includes the growing tip of the stem plus one or more nodes below it. A node cutting (sometimes called a stem section cutting) is a section of stem with one or two nodes but without the growing tip. Both can produce new plants. Tip cuttings are often slightly faster because the tip contains high concentrations of auxin and active meristematic tissue. Node cuttings from the middle or lower part of a stem are more plentiful (you can take more of them from a single plant) and root reliably even without the tip. For chimeric variegated plants, it is worth selecting node cuttings specifically from stems with good variegation, as each node may have different variegation characteristics.
