![]() Mix an equal amount of herbicide with water to make a 50 percent solution. The most cost-effective option for larger projects is to use a glyphosate product with 41 percent or higher active ingredient. Glyphosate products with 20 percent active ingredient can be effectively used for some species but should not be diluted. Ready-to-use glyphosate products with less than 20 percent active ingredient will not consistently work for cut stump treatment. Products may vary in the concentration of these active ingredients, so look closely at the label. Herbicide products containing active ingredients glyphosate and triclopyr amine have little to no soil activity and are appropriate and effective for residential use. Herbicides with soil activity can affect nearby nontarget plants through root uptake and are not recommended for residential use. ![]() What herbicide should I use in residential areas? Delays in herbicide application may reduce effectiveness. It is best to treat immediately after cutting, within a few minutes at most. How soon after cutting do I need to apply the herbicide? This avoids leaving taller “ankle breaker” stumps that may be hazardous to walk or drive through. The best option is to cut close to the ground, leaving a 1- to 2-inch stump. Cut stump herbicide treatments are most easily applied with backpack sprayers or handheld pressurized spray bottles, but they can also be applied with a paintbrush. A handsaw or pruning shears are adequate for smaller stems as well. You typically need a good chainsaw for larger stems, although a lightweight brush saw is fine for smaller stems. This is evident when stumps appear to “bleed” water following cutting. The only time cut stump treatments should not be done is in the early spring when trees are experiencing strong upward sap flow. Temperatures are cooler, herbaceous vegetation is dormant, and undesirable critters are less active. While late summer through fall is often the optimal time, late fall may be the easiest time from an operational standpoint. What is the best time of year to use this method?Ĭut stump treatments with most woody plants can be done almost any time of the year. However, small stems less than a half-inch in diameter are not consistently controlled. The cut stump treatment method is effective on almost any size woody invasive plant, including large woody vines. For what size woody plants will this method work? Cut stump treatment is not recommended where thousands of stems per acre need to be treated or where trees or shrubs cannot be safely felled and piled if needed. This method can be used selectively with no damage to surrounding vegetation. Is a cut stump herbicide treatment the best option for my situation?Ĭut stump treatments are most useful where the target tree or shrub density is relatively low, manual labor is available, and dead standing trees and shrubs are not desired. Cut stump treatments are an effective method for woody plant control, including many invasive species.
