Dandelion, Top 10 Turf Weeds

#1: the Dandelion

Most of us are familiar with a Dandelion. They are found in lawns, landscape beds, woodland edges, and disturbed soils in sunny locations. They easily invade think lawns and other areas of bare soil.

They create bright yellow flowers primarily in spring and fall and each flower produces hundreds of seeds that are dispersed by the wind to spread more dandelions!

Dandelions are difficult to manually remove, you will need forward thinking with this weed as the tap root is big and has a large storge system. It is almost considered as a weed that can NO LONGER be pulled to effectively remove.

The BEST application to treat the dandelion is in the fall but a spring application of herbicide is beneficial too. 

Yellow Wood Sorrel, Top 10 Turf Weeds

#2: the Yellow Wood Sorrel

Yellow Wood Sorrel is a perennial weed commonly found in low nitrogen lawns, roadsides and can even grow in the cracks of sidewalks.

It is a thin, clover like trifoliate (3 leaflets), heart-shaped leaves and yellow flowers with five petals that blooms from May to September.

Yellow Wood Sorrel is a difficult, aggressive garden weed.  It is recommended to be removed or treated before it shoots seeds, which are violently ejected from the plant’s dry seed capsules.  

The BEST application to treat Yellow Wood Sorrel is before it flowers – spring application.

White Clover, Top 10 Turf Weeds

#3: the White Clover

White Clover is a perennial broadleaf weed that is commonly found in low nitrogen lawns (it is an indicator of low nitrogen).  

White Clover has leaflets that are oblong to wedge-shaped with a variegated white or red “watermark”.  The stems grow horizontal near the soil and the round head has a white to pink flower.

White Clover is considered invasive and can be difficult to eradicate as it’s an aggressive, crawling plant.  It will compete with most lawn grasses and form large mats that blot out sun to other plants.  White Clover can also tolerate and adapt to different mowing heights.  

While spring applications can be effective, the fall application is the BEST time to control White Clover.  Our fall application is the BEST because that is when plants start to store energy in the storage structure.

Crabgrass, Top 10 Turf Weeds

#4: Crabgrass

Crabgrass is a weed commonly found in thin or bare areas of your lawn.  Crabgrass germinates in the spring when soil temps reach 50 degrees F.  It can crowd out good grasses in your lawn and likes short mowing heights.  If you notice crabgrass in your lawn, raise your mowing height to 3-4” or higher and plan for your applications to treat this weed.  If you don’t remove crabgrass before it disperses its seeds, you will have to continually deal with this pesky weed.

Crabgrass looks like a course, light green clump of grass.  Its sprawling stems resemble legs of a crab.  

A pre-emergent herbicide is the best application to treat crabgrass and attempt to get ahead of it before germination.  TIMING is very important with crabgrass because there is a narrow window to control crabgrass seedings.  After this time has passed, you will have to change the mode to control it.

Creeping Charlie, Top 10 Turf Weeds

#5: Creeping Charlie

Creeping Charlie is a perennial, evergreen weed in the mint family.  It will GROW ANYWHERE and quickly becomes a nuisance weed in lawns!  It will infiltrate lawns that have been neglected and will suppress the growth of surrounding plants or grass.

Creeping Charlie produces bright green, round or kidney-shaped leaves that have scalloped edges.  In spring, small bluish-purple, funnel shaped flowers appear.

Creeping Charlie is an early spring bloomer (April-May).  You can treat and attempt to control this weed throughout the growing season, but it is BEST treated and controlled with a fall application.  

Quack Grass, Top 10 Turf Weeds

#6: Quack Grass

Quack Grass is a cool season creeping perennial grass.  It can look like ryegrass and maybe even closely resemble crabgrass.  It can grow fast, will quickly take over your lawn and stunt the growth of other plants.  It’s strong, has a deep root system and can be one of the hardest weeds to eradicate.  It is NOT effective to dig up.

Quack Grass has clasping auricles (ear like projections) that are located at the base of the blade right before it reaches the stem. 

It is best to apply applications when the weed is young, fully green, actively growing and not under drought stress. 

Black Medic, Top 10 Turf Weeds

#7: Black Medic

Black Medic is a common, prostrate broadleaf weed.  It is often found in dry, sunny areas in turf and can be a nuisance in gardens.  Black medic can be an indication of low soil nitrogen and will compete with grass. It spreads easily by seed and will form large colonies if left untreated.

The plant’s dark green leaves are like clover leaves. This weed will produce bright yellow flowers throughout the growing season. 

It is recommended that you have good turf management practices with high mowing, proper fertilization, and irrigation to make it more difficult for Black Medic to persist.  

It is important to control this weed before flowering and seed sets so the BEST time to control and apply applications for Black Medic is in the late spring through early summer and then again in mid-autumn. 

Rough Blue Grass, Top 10 Turf Weeds

#8: Rough Bluegrass

Rough Bluegrass is a spreading, aggressive, grass-like weed.  Once it gets into your lawn, it takes over the grass already there, then can die back in summer heat, leaving bare spots where your grass once grew.

Rough Bluegrass appears shiny, pale green and turns a red, bronze hue when stressed, such as during drought or periods of heat.  It often grows in clumps, forming patches in the turf when growing alongside other grass varieties.

It spreads by seed and vegetatively.  Seeds can easily contaminate seed mixes or soil material.  It spreads fast during cool weather, especially in shaded areas.

It is recommended that you have good turf management practices with high mowing (3.5-4.5”) and water infrequently to keep Rough Bluegrass at bay.  Digging up or hand pulling of Rough Bluegrass is also no longer effective.

It is important to provide regular fertilization and weed control each year to combat Rough Bluegrass. Lawns that are treated and lush and healthier make it harder for this weed to invade. 

Broadleaf Plantain, Top 10 Turf Weeds

#9: Broadleaf Plantain

Broadleaf Plantain is a popular weed as it adapts well to most turf sites including dry or wet conditions.  This weed may even stay conspicuously green during drought.  Broadleaf Plantain will reproduce by seeds which can emerge in late spring through midsummer, and even occasionally in the fall.

Broadleaf Plantain has a short, thick tap root that forms a rosette of leaves that lay flat to the ground.  This weed will flower in the summer on leafless, unbranched stalks that originate from the base of the plant.

It is important to provide regular fertilization and weed control each year to attempt to combat Broadleaf Plantain when it is actively growing, especially in the spring and fall. 

Prostrate Spurge, Top 10 Turf Weeds

#10: Prostrate Spurge

Prostrate Spurge is a popular weed that can be found just about anywhere!  You will often find it in dry, sandy, nutrient poor soils.  It will grow in turfgrass, driveways, sidewalks, and landscaped areas and can withstand low mowing heights.  This weed often germinates in June and will continue to germinate throughout the growing season.  

Prostrate Spurge is pale green in color and has egg shaped leaves with a pinkish color stem. The weed is anchored by a central shallow taproot that forms a ground-hugging mat that will grow outward throughout the turf canopy.  This weed will flower, produce viable seeds very quickly, and spread. 

It is important to provide regular fertilization and weed control each year to attempt to combat Prostrate Spurge because it can become resistant, and it should be treated before it flowers and produces seeds.
