Scissor-type pruning tools such as pruning shears and lopping shears are preferred for branches of what diameter?

Scissor-type pruning tools, including pruning shears and lopping shears, are designed for cutting branches that are generally less than 1 inch in diameter. These tools function effectively on smaller branches because their scissor-like action allows for a clean, precise cut without crushing the tissue of the plant. This minimization of injury is crucial for maintaining the health of the tree, as it helps prevent disease and promotes faster healing.

When dealing with branches larger than this diameter, the mechanical advantage and cutting efficiency of scissor-type tools decrease, making it difficult to achieve the same quality of cut. Larger branches may require different tools, such as saws or anvil-type pruners, which are better suited for handling thicker wood. Therefore, for optimal results and to preserve the integrity of the plant, scissor-type pruning tools are best utilized on branches that are less than 1 inch in diameter.
