As winter blankets pastures, the battle against stubborn multiflora rose and unwanted scrub trees continues. These woody invaders not only compete for nutrients but also pose a threat to livestock with their thorns. Taking action during winter dormancy provides a strategic advantage for effective control.
Mechanical Control: Cutting or pulling during unfrozen ground conditions yields immediate results, but persistence is key as remaining roots may sprout new plants.
Herbicide Tactics: Winter offers an opportune time for herbicide application. Spotting short grass allows for targeted treatment of small multiflora rose, honey locust, or autumn olive. Basal bark or cut stump treatments during dormancy minimize damage to non-target plants.
Basal Bark Application: Utilize triclopyr-based herbicides (e.g., Remedy, Garlon 4) mixed with oil as a basal bark treatment. Apply from the ground to 15 inches up the plant, targeting trees up to 6 inches in diameter.
Cut Stump Treatment: Address persistent shoots with cut stump treatments, using triclopyr-based or water-based herbicides like glyphosate. Apply promptly after cutting to prevent surface sealing.
A cautionary note: If treating plants with root grafts to desirable trees, consider potential effects on non-target trees, though this is usually more relevant in woodlots than pastures.
Investing in small spray equipment, such as a backpack sprayer, ensures cost-effective application. Always adhere to product label instructions, including grazing restrictions.
Winter provides a strategic window to reclaim pastures from woody intruders, promoting a healthier and more productive grazing environment.
