Kill Crabgrass and/or Bindweed Without Killing the Desirable Grass

Crabgrass is an annual grass that grows in lawns that have bare spots or are being mowed too short.

Crabgrass does not grow in every lawn but it is easily controlled with a special weed control called Drive XLR8.

Crabgrass vs Tall Fescue

Crabgrass Weed Killer

Crabgrass Control for Lawns

Crabgrass is an annual grass that germinates in the weak or damaged spots of lawns during the month of June and can be seen until after the first frost which is typically in October. Crabgrass is most abundant on the edges of the lawn and often grows in the stressed areas of the lawn or in lawns that are being cut too short. Crabgrass will only grow if there is an opportunity for crabgrass to germinate in the lawn. A thick and dense lawn will never develop a crabgrass problem.

If crabgrass does grow in a lawn we use a special crabgrass killer called Drive XLR8 to kill the grassy weed quickly, After a crabgrass weed killer application it typically takes about 7-14 days for the weed to completely die. Crabgrass can be a problem for lawns in Boulder and Fort Collins, but it will only grow in lawns with stressed out turf or lawns that are being mowed too short.

Bindweed Weed Killer

Bindweed Weed Control for Lawns

Bindweed is a creeping weed that typically germinates in lawns in Boulder and Fort Collins from May through August. Bindweed has a very extensive root system and often is seen with white, pink, or yellow flowers. Bindweed can often take over an entire yard or native grass area and is not susceptible to weed control even by the strongest weed killers.

It is important to kill bindweed growing in a lawn because bindweed seeds can remain viable in soils for up to 50 years. Bindweed tends to be found in drought stressed lawns and can often be controlled long term with proper lawn watering and lawn mowing practices. If you have these weeds in your Boulder or Fort Collins lawns, we will only guarantee control if we use Drive XLR8 as a post-emergent bindweed killer.

Drive XLR8 for Crabgrass and Bindweed Killer is the only product that will kill and control crabgrass and/or bindweed with only one application.

FAQ - Drive XLR8

How does crabgrass spread in a lawn?

Crabgrass is an annual grass that germinates from seed every year. It grows in clumps and you will begin to see the young crabgrass blades emerge in areas of the lawn that are thin or damage from late June through August. Crabgrass typically grows only in areas of the lawn that are thin because crabgrass is not very competitive and cannot grow if other grasses are already established. Near the edges of the turf where the grass abuts the sidewalk and lawns that are mowed too short are more likely to have crabgrass problems than lawns that are mowed at three inches or taller. You can kill crabgrass in a lawn by using Drive XLR8.

Lawn Care Services FAQ

When does crabgrass germinate in a lawn?

Crabgrass germination typically occurs in early May when soil temperatures reach 62 degrees Fahrenheit. The young seedlings will typically not be visible until sometime around the middle of June. They are easily identified because they are a lime-green colored grass that grows in areas of the lawn that are thin, heat and drought stressed or in lawns that are mowed too short.

How to kill bindweed in grass?

Bindweed is most prevalent in lawns that are dry and bindweed can take over entire lawns if left untreated. We tend to see bindweed growing in lawns that are drought stressed and are not being watered deeply and infrequently. Bindweed can also grow in flower beds and rock gardens. We kill bindweed that is growing in both the grass areas and flower beds by using a special application of a weed killer called Drive XLR8.
