Louisiana's lush landscapes, humid climate, and fertile soils offer a haven for both desired plants and, unfortunately, unwelcome invaders known as broadleaf weeds. These persistent and nuisance invaders can disrupt the beauty and health of lawns, gardens, and agricultural fields. This article will explore the world of broadleaf weeds in Louisiana, their common types, challenges, and, most importantly, effective strategies for managing and controlling them.
Broadleaf weeds may be a persistent challenge in Louisiana's unique climate, but you can regain control over your outdoor spaces with proper management techniques. By understanding the types of broadleaf weeds in the region, identifying them, and employing control and preventative methods, you can achieve a lush, vibrant landscape that thrives despite these pesky invaders. A proactive approach is key to maintaining the beauty and health of your lawn in the face of broadleaf weed challenges.
Broadleaf weeds are characterized by their wide, flat leaves and distinct growth habits that differentiate them from the grasses around them. In Louisiana, several common varieties of broadleaf weeds can cause trouble for property owners.
Chickweed (Stellaria media) is a common weed in Louisiana. It is a cool-season annual plant germinating in the fall and produces flowers in the spring. Chickweed is found in various habitats, including lawns, gardens, fields, and roadsides. Considered a prolific seed producer, it can quickly spread and produce up to 100,000 seeds, which can remain viable in the soil for several years. Chickweed is not considered a harmful weed, but it can be unsightly and crowd out other plants. It can also be a nuisance in lawns, making mowing difficult. Small infestations can be managed with hand-pulling.

Dollarweed (Hydrocotyle spp), or pennywort, is a perennial weed common throughout Louisiana. It is typically found growing in lawn areas with moist or wet soil. Dollarweed is difficult to control because it spreads through seeds and rhizomes. Rhizomes are underground stems that can produce new plants, which make this plant difficult to control with methods such as hand-pulling. Herbicides are the most effective and most recommended method to eradicate these problematic weeds. Mulching is considered the best way to prevent dollarweed from germinating in the first place.
Identifying features of dollarweed include:
Spotted spurge, also known as prostrate spurge, milk purslane, or spotted sandmat, is a fast-growing annual plant in the spurge family (Euphorbiaceae). Native to North America, and is now found in many parts of the world, including Louisiana. Spotted spurge is common in lawns, gardens, and other disturbed areas, thriving in a humid environment. Known as prolific seed producers, spotted spurge seeds can remain viable in the soil for several years. Spotted spurge is not considered harmful, but it can be unsightly and crowd out other plants. It’s also known for being difficult to mow, making large infestations especially problematic. Herbicides are the most effective method of getting rid of these weeds.

Thistles are commonly found worldwide and are one of the most recognizable weeds that thrive in Louisiana. Various types of thistles can be found growing anywhere from roadsides, garden beds, cracks in the side, and even found in swamps. These resilient weeds spread quickly, and their seeds remain in the soil for years. Small infestations can be managed with hand-pulling, but large infestations can only be managed by the correct combination of herbicides.
Here are some of the thistles found all over Louisiana:
Asiatic hawksbeard (Youngia japonica) is a common weed in Louisiana. It is an annual plant that can grow up to 3 feet tall. It has yellow flowers that bloom in the spring and summer. It is native to Asia but has been introduced to many other parts of the world, including Louisiana. It is a prolific seed producer and can quickly spread. The seeds can remain viable in the soil for several years. Herbicides are the most recommended method of eradicating these nuisance weeds.
