When making a reduction cut, a branch is cut back to a lateral branch that is:

• A. At least one-fourth the diameter of the branch being removed
• B. The same size as the branch being removed
• C. Larger than the branch being removed
• D. At least one-half to one-third the diameter of the branch being removed

Answer: (D)

A reduction cut works by shortening a branch to a more substantial side branch so that growth is redirected and the wound can heal cleanly. The lateral branch that you cut back to should be large enough to act as a strong anchor for new growth, but not so large that the cut removes too much tissue or creates an awkward, heavy limb. The guideline is to choose a lateral that is roughly one-half to one-third the diameter of the branch being removed. This size provides enough tissue to form a proper callus and a stable union, helping the wound seal and the new growth to develop smoothly. If the lateral is much smaller, the wound is disproportionately large relative to the remaining structure, increasing the risk of decay and poor healing. If the lateral is the same size or larger than the branch being removed, the cut can be more disruptive to the tree’s architecture and growth pattern, making the reduction less effective. By using a lateral within the one-half to one-third range, you balance wound healing, structural integrity, and the desired reduction of the branch.
