Shortening a trailing vine
Trace one long vine back to a healthy leaf node. Keep the rest of the plant out of the blades.

Before you start
On a branching vine such as pothos, separate the stem you want to shorten from its neighbors. Decide how much to keep, then choose a healthy node near that point.
How to do it
Hold the vine so the node is visible. Snip on the tip side of the node, leaving the node and its leaf on the plant. Let the vine settle and check the shape before trimming another.
When to stop and recheck
If a vine is just in the way, try guiding it onto a support first. If several vines are growing long and bare, check light and care before cutting them all back.
