What is the preferred method for pruning cuts to promote wound closure?

• A. Cut just outside the branch collar
• B. Cut flush with the branch
• C. Cut into the branch collar
• D. Remove entire branch including collar

Answer: (A)

The main idea is where you place the pruning cut relative to the branch collar, the built‑in wound‑closing area where the branch meets the trunk. Cutting just outside the branch collar preserves that collar tissue on the trunk, allowing the tree to form callus tissue and seal the wound efficiently as it grows. This keeps the wound smaller and directs natural healing to occur from the collar area, which helps minimize decay and infection. If you cut flush with the branch, you remove the collar tissue and leave a larger wound that the tree has to close, which slows wound closure and increases the chance of decay. Cutting into the branch collar damages the collar itself, disrupting the tree’s natural sealing process. Removing the entire branch including the collar eliminates the collar tissue entirely, producing an even larger wound and further hindering closure. So, the preferred method is to cut just outside the branch collar to promote rapid and effective wound closure.
