Common Virginia Weeds

Prestigious Turf Management has put together a guide to common Virginia Weeds.  We have tailored lawn treatment programs that are designed to eliminate these weeds.  If you should decide to over seed your lawn, the Yorktown Feed & Seed Store has high quality bulk seed for sale!

Annual Bluegrass (Poa annua)

Annual bluegrass is a light green, low growing bunch type grass. It’s easy to pick out in most lawns due to its light color. Annual bluegrass does well in lawns that are cut short. It also likes areas with low pH, compaction, poor drainage and/or shade. When turf is fertilized at improper times and given frequent light watering, tends to favor annual bluegrass. In irrigated lawns, annual bluegrass seeds can germinate and persist through the fall growing season.

Control: Management controls begin with getting a soil test and adjusting the pH as needed. Improve surface drainage by aeration and topdressing if needed. Increase mowing height and overseed thin areas to limit the ability of this weed to establish in the lawn. Clean mowing equipment between using the mower in an area with annual bluegrass and annual bluegrass free area to avoid spreading seeds.

Corn Speedwell (Veronica arvensis)

Corn speedwell is a small, low-growing annual that often goes unnoticed. Speedwell can be a common weed problem in newly established areas of cool-season turfgrass. Upper and lower leaves of corn speedwell differ in appearance and arrangement. Lower leaves are rounded, toothed and arranged opposite. Upper leaves are smaller, pointed and arranged alternate.

Control: Control is often difficult due to speedwell’s inconspicuous nature. Typically, by the time it’s noticed it has already flowered and set seed. Speedwell is often found in dry areas with low soil fertility. Improving the turf with overseeding, proper fertilization and proper irrigation can help prevent speedwell.


 

Bittercress (Cardamine hirsuta.)

Bittercress has deeply loped leaves that are larger at the base of the plant than the top. Small white flowers are held in clusters at the top of branches. Bittercress seeds germinate in 5 days and can produce seedling in 5 weeks after germination.

Control: Manage fertility to favor turf by fertilizing based on soil testing and adjusting how much nitrogen is applied. Improve surface drainage and where appropriate, selective pruning to reduce shade. Overseed thin areas as needed to limit the ability of these weeds to establish or returning to the lawn.


 

Common Chickweed (Stellaria media) and Mouse Ear Chickweed (Cerastium vulgatum)

Chickweed and mouse ear chickweed are among the most common cool season weeds. Common chickweed is an annual, while mouse ear chickweed is either an annual or perennial. Chickweed prefers heavy, wet/poorly drained soil and thrives well in the shade.

Control: Steps may need to be taken such as improving drainage, aeration and a top dress with compost, mow high and overseed to thicken the lawn. These steps can all help make conditions more favorable for turf than chickweed. Where practical, selective pruning of nearby trees and shrubs to increase light will also help grass compete with chickweed.


 

Ground Ivy aka Creeping Charlie (Glechoma hederacea) and Wild Violet (Viola sp)

Ground ivy and wild violet are stubborn weeds with similar appearance. Ground ivy is a sprawling weed that grows well in moist soils under shade and in full sun. It also likes wet/poorly drained soils. Violets prefer shady conditions where they have the competitive edge over turf.

Control: When possible, increase available light through selective pruning of nearby trees and shrubs to favor grass over these weeds. Increase mowing height and overseed areas of thin turf to suppress weeds. Improving drainage will make conditions less favorable for ground ivy. These weeds are resistant to many broadleaf herbicides which takes several precise applications by a trained professional to control. They are best treated in the spring, and often need repeated applications for full control.


 

Henbit (Lamium amplexicaule) and Deadnettle (Lamium purpureum)

Henbit and deadnettle are winter annuals that look alike. Both have square shaped stems and flower in the spring. These weeds prefer high fertility soils.
