What are Plant Nodes & How to Use Them

Plant nodes are bumps on plant stems which allow plants to be properly pruned and propagated. These node locations are easy to find and are the location of further growth of a plant. This article will provide you with more information on nodes, how to identify them, and how to use them when pruning or propagating your plant.

What is a Node & Note Identification

A plant stem includes both nodes and what is referred to as internodes. Before we get into a node, the internode is the space of the stem between nodes. A node is where we are going to focus. Nodes are little bumps along the plant stem. It is at these places where new stems, leaves, and roots grow. These bumps often appear hard or calloused and sometimes feature small calloused looking stems. These calloused stems might look like a root or stem attempted to grow but then calloused over.

Plants with Nodes

Examples of plants that have highly visible nodes include Pothos plants, Arrowhead plants; though many plants have visible nodes where the leaves are located on the plant’s stem.

Nodes & Pruning

Nodes are important when pruning. When you are pruning your plants, you want to cut the stem so that the node is not cut but is left near the end of the remaining stem. If you cut on the other side of the node you are left with internode which does not sprout new branches.

Nodes & Propogation

Like with pruning nodes are important in propagation. As noted before, the node is the place on a stem where new branches and leaves are likely to grow from. That being said, nodes are necessary to propagate new roots as well. Taking a cutting of the plant which includes at least 2 nodes and at least 1 leaf and placing it in either water or moist soil, will likely grow roots. Be sure the nodes are in the water or moist soil for this process to work properly.
