Summarize the following:
Although bamboo has a rapid growth rate, you only need to prune it once a year if you do a really thorough job. Pruning your bamboo more frequently can actually cause it to send off more shoots. Mark on your calendar when to start pruning and coordinate it with fertilizing. Branches and leaves can cut your skin in a bamboo grove, so it’s a good idea to wear sturdy gloves, long pants, and a long-sleeved shirt. Wearing sturdy gloves will also make it easier to handle and cut the canes. Nodes are where the pieces of the stem join together. You’ll see a slight bump or bulge on the stem shaft indicating this joining. To trim down the height of a bamboo plant, locate a node. Then, position your shears or plant saw right above it and cut across. Making your cut above the node also makes the pruning process easier, as these spots are less thick. Bamboo is very strong and if you cut it at an angle, it can be quite dangerous. Keep your cuts blunt and horizontal to minimize the risk. You should be able to use hand clippers for most cane. However, if the cane is rather large, opt for a pruning hand saw and extension.

Summary:
Prune once a year in late summer or early fall to minimize spreading. Wear eye and hand protection. Cut above a node if you are trying to reduce height. Make straight cuts across the bamboo stem.
