Brentwood lawn care: Weed control services

This page describes weed control, one in a series of services included in the Brentwood lawn care category, which include all the lawn care services you need to keep your lawn looking healthy and lush.

Without taking preventive measures at the right time, you could be facing a patchwork of color and texture within your lawn. Weedy grasses often contrast greatly with desirable turfgrasses (lawn grass) and can be difficult to eliminate once they’ve become established in your lawn. Broadleaf weeds, including the infamous dandelions which rise well above the turf producing flowers then, are even more visible within a uniform carpet of green.

Lawn weeds: Unwelcome guests

Weeds also pose a major problem in landscape beds in spring. Instead of hand weeding, you may be able to use a pre-emergent herbicide to control weeds that grow from seed as the weather warms up. Read labels carefully before selecting and using any of these products to make sure they are best suited to your particular weeds and won’t damage surrounding plants.

Grassy weeds: Stealthy invaders

Grassy weeds, or unwanted grasses growing in the lawn, can be subdivided into annual and perennial grasses. Annual grassy weeds, such as crabgrass and annual bluegrass, are generally easier to control than perennial grassy weeds like dallisgrass and bentgrass. However, annual grassy weeds are also notorious for their ability to produce seed. This makes them difficult to eliminate totally from your lawn and explains their survival from year to year. A well-timed treatment prior to spring germination can prevent a summer invasion of crabgrass, foxtail and sandbur grasses. Left uncontrolled from seed, crabgrass alone can choke out desired turf grasses and develop ugly seedheads in the fall that lay the groundwork for next season’s crop.

Perennial grasses generally grow in hardy clumps (e.g., dallisgrass, orchardgrass, and tall fescue) or through very aggressive creeping stems (quackgrass, bermudagrass, bentgrass, nimblewill). The challenge is removing perennial grassy weeds without harming the lawn grass you’ve worked so hard to cultivate.

Broadleaf weeds

Broadleaf weeds are characterized by their growth pattern. Plants that grow from the center of the plant are called rosette weeds, while weeds that sprawl along the surface of the ground are known as creeping weeds.

Common rosette weeds

Dandelions, plantains, and docks are examples of rosette weeds. Their leaves radiate from one central point on a very short stem that barely rises above soil level, making them almost impossible to pull cleanly from the ground. In addition, these plants produce flowers on the tops of tall stalks, further ruining the look of your lawn.

Common creeping weeds

Clover, chickweed, and lespedesa are creeping weeds that can create the appearance of large unsightly patches in the lawn, especially if several of the weed plants overlap each other. As the stems radiate from a central point and hug the ground, they can establish roots at multiple points. This makes them more difficult to remove, and when they are pulled, they can leave large bare spots in your lawn.

How can I get rid of crabgrass?

Crabgrass is an aggressive weedy lawn grass that emerges each spring from seed. Mow your lawn high to thicken it and reduce the ability of crabgrass to establish in your lawn. If you use a crabgrass preventive, it must be applied before seed germinates in late spring.

I treated my lawn last summer for dandelions, yet they always seem to reappear in spring. Why?

Dandelions set seed in puffballs that are released by the wind and can be blown from one lawn to the next. Most dandelion seed germinates in the fall. The plants you see in your lawn this spring probably germinated after you applied a weed control last summer. Reapply a control product this spring once air temperatures rise to the proper level for the materials to work.

How do I control wild violets?

Wild violets are perennial plants that emerge each spring, forming beautiful, delicate flowers in late April to early May. Control is very difficult and usually requires a formulated application of a weed control product in spring for best results. Control will take more than one application over several seasons. Wild violets are favored by moist, shaded growing conditions. Eliminating the weed without considering site conditions is a short-term solution to this weed’s persistence.
