For cut surface applications, which timing is correct for applying the herbicide after making the cut?

Applying the herbicide immediately after making the cut is best because the freshly exposed cambial tissue is highly permeable and actively takes up the chemical. This quick uptake allows the herbicide to move systemically through the stump to suppress or kill sprouts effectively. If you wait even a few days, the cut surface begins to dry and seal with protective tissue, reducing penetration and lowering efficacy. Delays of weeks or exposure to frost further hinder uptake and can lead to poor control of regrowth.
