Broadleaf weeds can quickly take over your lawn or garden if left unchecked. They are easier to spot than grassy weeds due to their wide leaves and distinct growth patterns.
In this guide, we’ll walk you through identifying common broadleaf weeds, preventing their spread, and applying effective control methods to keep your landscape healthy and weed-free.
Broadleaf weeds are a diverse group of unwanted plants that feature broad, flat leaves, often with visible veins and a variety of flower shapes. Unlike grassy weeds, they typically grow in clusters and are easily distinguishable from turfgrass, making them more noticeable in lawns and gardens.
Recognizing broadleaf weeds early is key to effective control. Most have distinct leaf shapes, growth habits, and flower types. Below are some of the most common species you’re likely to encounter and how to spot them.
Also known as pennywort, dollarweed has shiny, round leaves about the size of a silver dollar. It thrives in moist, poorly drained soils and often spreads through underground stems.
This low-growing weed has small, oval leaves and delicate white flowers with five deeply lobed petals. It prefers cool, shady areas and spreads quickly in early spring and fall.
There are two common types: broadleaf and narrowleaf plantain. Both form low-growing rosettes with parallel-veined leaves and seed spikes. They tolerate compacted soil and frequent foot traffic.
Prostrate spurge grows flat against the ground and has small, oval leaves often marked with a reddish spot. When broken, it oozes a milky sap and thrives in hot, dry conditions.
Clover has trifoliate (three-part) leaves and small white or pink flower heads. It’s often a sign of nitrogen-poor soil and is common in under-fertilized lawns.
Also known as common lespedeza, this weed has wiry stems and trifoliate leaves with parallel veins. It grows low and spreads across warm-season lawns in late summer.
Thistles are spiny, upright weeds with lobed leaves and purple flower heads. Once established, they grow tall and are difficult to control, often thriving in disturbed or neglected areas.
Broadleaf weeds are more than just unsightly. They can interfere with healthy lawn growth and signal deeper soil or care issues. Here’s how they impact your yard.
Broadleaf weeds have different growth patterns, leaf shapes, and colors from turfgrass. Even a few scattered plants can disrupt your lawn's overall appearance and uniformity.
These weeds typically tend to steal moisture, nutrients, and sunlight from your grass. As a result, turf weakens, leading to thinning areas that are more susceptible to additional weed invasion.
Broadleaf weeds can create shelter and breeding grounds for harmful insects and pathogens, further stressing your lawn and increasing your maintenance burden.
Managing broadleaf weeds takes a proactive, multi-step approach. Whether you’re aiming for organic solutions or conventional treatments, the strategies below can help you reduce and prevent infestations.
A dense, vigorous lawn is your best natural defense against weed invasion. Strengthen your grass with good lawn care habits:
Weeds like dollarweed and chickweed thrive in moist environments. Address the excess moisture by:
Pre-emergency herbicides prevent weed seeds from germinating. Use them in early spring or fall to target specific seasonal weeds.
When weeds are already visible, apply selective herbicides that target broadleaf species without harming your lawn.
Dealing with broadleaf weeds doesn’t have to be a constant battle. With proper identification, preventive care, and timely treatment, you can keep your lawn in top shape throughout the growing season.
