Rose of Sharon is a flowering shrub that many gardeners plant on purpose, but it can become invasive when seedlings spread into lawns, fence rows, and natural areas. It produces thousands of seeds per plant, and those seeds germinate readily in disturbed soil. Controlling it requires herbicides that kill the woody root system, not just … Read more
St John’s wort is a perennial broadleaf weed that spreads aggressively through creeping roots and seeds, forming dense patches in pastures, fence rows, roadsides, and disturbed ground. It is toxic to livestock and can cause photosensitivity, weight loss, and death when consumed in quantity. Because it is a broadleaf species, selective herbicides control it without … Read more
Florida pusley is a low-growing summer annual broadleaf weed that forms dense mats in lawns, gardens, and disturbed areas across the southern United States. It spreads rapidly through seeds and thrives in thin, weak turf where competition from desirable grasses is low. Because it is a broadleaf species, selective broadleaf herbicides control it without harming … Read more
Virginia creeper is a native North American vine that many homeowners treat as a weed once it climbs trees, fences, and siding. Because it is a broadleaf woody vine, controlling it requires herbicides that reach the roots, not just burn the leaves. The right product depends on where the vine is growing and what surrounding … Read more
Fence rows collect weeds, brush, and volunteer trees faster than almost any other part of a property. They are hard to mow, easy to neglect, and often the first place invasive species take hold. Choosing the right herbicide for fence rows means matching the product to the vegetation you need to control and the surrounding … Read more
Dichondra is a low-growing perennial broadleaf plant that many homeowners treat as a weed, while others cultivate it as a warm-season lawn alternative. Because it is a broadleaf species, controlling dichondra without harming surrounding turf requires a selective broadleaf herbicide. The right product depends on whether you are managing common turfgrass, warm-season grass, or dichondra … Read more
Post emergent herbicides are applied after weeds have emerged from the soil, targeting the leaves and stems of actively growing plants. They are the second half of most weed-control programs: pre-emergent products stop seeds from germinating, while post-emergent products kill the weeds that got through. Understanding the major post-emergent options helps growers and gardeners match … Read more
Group 1 herbicides are ACCase inhibitors used primarily for post-emergence control of susceptible grass weeds. They inhibit acetyl-CoA carboxylase (ACCase), an enzyme involved in fatty-acid biosynthesis, disrupting the growth of susceptible grasses and making this herbicide group an important tool in many weed-management programs. The Group 1 designation comes from the HRAC/WSSA herbicide site-of-action classification … Read more
Orange hawkweed dies when its crown, stolons, and rhizomes are destroyed — not just when the leaves are burned off. Hand-pulling, selective herbicides, and smothering each kill different parts of the plant, which is why a single treatment rarely works. Effective control combines two or more methods over several seasons. The right approach depends on … Read more
Orange hawkweed facts help gardeners, farmers, and landowners recognize one of the most aggressive wildflower invaders in North America. Orange hawkweed (Hieracium aurantiacum) is a low-growing perennial with bright orange dandelion-like flowers and hairy leaves. It spreads rapidly through seeds and creeping stems, forming dense patches that crowd out native plants and pasture grasses. Native … Read more
