Common Broadleaf Weeds in Kansas: Identification and Control
with desirable plants for nutrients, water, and sunlight, leading to a less attractive and healthy outdoor space. This blog will cover common broadleaf weeds in Kansas and offer effective weed control strategies using pre-emergent and post-emergent herbicides.
Understanding Broadleaf Weeds
Broadleaf weeds are distinct from grassy weeds due to their broader leaves and varied growth habits. They can quickly invade and overwhelm lawns and garden beds if not managed properly.
Common Broadleaf Weeds in Kansas
Dandelion (Taraxacum officinale)
Description: Dandelions are easily recognizable by their bright yellow flowers and deeply toothed leaves. They have a deep taproot that can make removal challenging.
Control: Use a post-emergent herbicide that targets dandelions. Pre-emergent herbicides can also be effective if applied before seeds germinate.
Clover (Trifolium spp.)
Description: Clover species like white clover and red clover are characterized by their small, rounded leaves and can quickly spread in lawns and gardens.
Control: For clover control, use a post-emergent herbicide designed for broadleaf weeds. Pre-emergent herbicides can help prevent new clover infestations.
Chickweed (Stellaria media)
Description: Chickweed is a low-growing weed that forms dense mats. It thrives in cool, moist conditions and can quickly cover garden beds.
Control: Apply a post-emergent herbicide to target established chickweed. A pre-emergent herbicide can also help manage its growth before it becomes a problem.
Plantain (Plantago spp.)
Description: Plantain species, such as broadleaf plantain and buckhorn plantain, have rosette growth with large, broad leaves. They are resilient and can be difficult to remove.
Control: Use a post-emergent herbicide that is effective against plantains. Regular mowing and lawn maintenance can help reduce plantain populations.
Purslane (Portulaca oleracea)
Description: Purslane is a succulent weed that grows in warm, sunny areas. It spreads rapidly and can form dense mats.
Control: A pre-emergent herbicide can help prevent purslane seeds from germinating. For existing weeds, use a post-emergent herbicide designed for broadleaf plants.
Bindweed (Convolvulus arvensis)
Description: Bindweed is a creeping perennial with white or pink funnel-shaped flowers. It can smother other plants and is tough to control.
Control: Post-emergent herbicides that target bindweed are most effective. Manual removal and regular monitoring can also help manage its spread.
Lambsquarters (Chenopodium album)
Description: Lambsquarters is a fast-growing annual weed with diamond-shaped leaves. It is commonly found in disturbed soils and garden beds.
Control: Apply a pre-emergent herbicide to prevent lambsquarters from sprouting. For existing plants, use a post-emergent herbicide.
Knotweed (Polygonum spp.)
Description: Knotweed, including Japanese knotweed, is known for its vigorous growth and ability to spread rapidly.
Control: A targeted post-emergent herbicide is effective for managing knotweed. Proper lawn care and regular monitoring can help keep it in check.
Common Mallow (Malva neglecta)
Description: Common mallow has round, lobed leaves and pink to purple flowers. It is often found in lawns and gardens.
Control: Use a post-emergent herbicide to target common mallow. Pre-emergent herbicides can also help manage its growth before it becomes established.
Henbit (Lamium amplexicaule)
Description: Henbit is a winter annual with square stems and purple flowers. It is commonly seen in cool, shady areas.
Control: Apply a pre-emergent herbicide in the fall to prevent henbit from germinating. For existing weeds, use a post-emergent herbicide.
Oxalis (Oxalis spp.)
Description: Oxalis, including yellow woodsorrel and creeping oxalis, has clover-like leaves and can form dense patches.
Control: Use a post-emergent herbicide specifically designed for oxalis. Regular lawn maintenance can help reduce its presence.
Redroot Pigweed (Amaranthus retroflexus)
Description: Redroot pigweed is a summer annual with reddish stems and broad, lance-shaped leaves. It is commonly found in gardens and disturbed areas.
Control: Apply a pre-emergent herbicide to prevent redroot pigweed from sprouting. For established weeds, use a post-emergent herbicide.
Effective Weed Control Strategies
To manage broadleaf weeds effectively, follow these strategies:
- Pre-Emergent Herbicides: Apply these herbicides before weeds germinate to prevent new infestations. Timing is crucial for optimal results.
- Post-Emergent Herbicides: Use these to target existing weeds. Choose herbicides specific to the type of weed for best results.
- Regular Maintenance: Proper lawn care, including mowing and fertilization, can help prevent weed problems and reduce the need for herbicides.
