Removing Wire from your Bonsai
Wire cannot stay on forever, usually it can stay for about 6 months, but that depends on the time of year. For example in the winter, the tree isn't doing a lot of growing so it will take longer for the diameter of the branch that has been wired to expand enough to create a problem. In the spring and early fall ( September-October) many trees are in active growth, so you need to check the wire more frequently.
