When removing a branch that is 9 inches in diameter, what is the appropriate minimum diameter for a lateral that should be left uncut?

When removing a branch that is 9 inches in diameter, it is important to consider the health and stability of the tree when determining the appropriate minimum diameter for a lateral branch that should remain after the cut. Leaving a lateral branch of at least 3 inches in diameter allows for better growth and healing for the tree.

Larger lateral branches can help support the tree's structure, maintain its aesthetic form, and continue photosynthesis, which is crucial for the tree's health. Adequate lateral branches also help distribute weight across the tree canopy and can reduce the risk of disease by maintaining a more robust and well-balanced asset.

Choosing a smaller diameter lateral branch to leave uncut might not provide sufficient structural support or health benefits, while selecting a larger diameter may not be necessary, potentially leading to unnecessary loss of resources from the tree. Thus, leaving a lateral of at least 3 inches in diameter strikes the right balance for the tree's health and structural integrity post-pruning.
