Bamboo is a plant that has been used for centuries for furniture, clothing, weapons and food. When planted, it will flourish quickly with a sufficient amount of water and sunlight. It is important to trim back bamboo stalks when they are broken or dead in order for your bamboo plant to grow productively. They can also be trimmed to remove stalks for ornamental value, cutting off green stalks and trimming them down to size.
Use sharp clean pruning scissors to trim bamboo stalks that are less then 1 1/2 inches in diameter, and use pruning shears or a fine toothed saw for stalks larger then that.
Cut off any dead or broken bamboo. For fresh ornamental bamboo, cut the stalk when it is green; this will reduce splintering.
Heat the fresh bamboo stalk before you cut it in any other places after trimming it from the plant. Place it in hot water to soak, in order to make trimming easier to reduce cracking.
Put the stalk on a sturdy surface so you can get an even cut without bending it or tearing fibers.
Use a utility knife with firm pressure, moving the blade back and forth across the stalk for an even cut until you completely cut through it.
