Lucky bamboo plants grow fast. If you've experienced an overabundance of growth on the plant, it can be safely trimmed and you can use the trimmed pieces to start new plants. Trimming the plant too aggressively can damage or kill it.
Find the node. The node is an area of new growth above an area of established growth. The easiest way to find the node is to look for rings around your plant. Locate the ring closest to the area you want to remove.
Make a cut just above the node. Use sharp, clean pruning shears and try to clip the section off in one snip. The cleaner the cut, the easier it will be for your plant to heal.
Pinch back extra leaves. Take the stem in your hand between your thumb and forefinger and pinch off the leaves. Leaves usually will branch out and grow thicker in the place just below a stalk trim. Use this pruning tip if you'd like to grow more leaves.
Don't trim too much. Follow the golden rule of pruning these plants, which is never to remove more than one third of the plant at any given time. Be sure to let your plant recover for a few weeks after a particularly aggressive pruning.
Use the remaining pieces to create a new plant. Place trimmed stalk pieces in water to form their own roots. They will grow into their own bamboo plants.
