Weed Control in Casper
Trugreen Weed Control of Casper · Casper, Mills, Evansville, Bar Nunn, Glenrock, Douglas
Weed Control: Dandelions, field bindweed, Canada thistle, kochia and crabgrass are the regulars in Casper lawns. We control them with the right product at the right time, then keep them out by making the turf too thick to invade.
Casper has two weed seasons. In May the broadleaf weeds flush: dandelion first, then clover, plantain and bindweed. In the heat of late June and July, crabgrass germinates in any thin spot once soil temperatures stay warm, and it keeps coming until frost. Each group needs a different approach, and timing is most of the battle.
Broadleaf weeds are controlled with a selective post-emergent that the grass tolerates, applied when the weeds are actively growing. Fall is the best window in central Wyoming: perennial weeds are moving energy to their roots in September, and they carry the product down with it, which is why a September application kills dandelions that a spring one only knocks back.
Crabgrass is an annual, so the win is stopping it before it sprouts. A pre-emergent barrier in late April or early May, ahead of the soil warming, prevents most of it. Where it has already come up, we treat it while it is small and work on the real cause, which is thin, dry turf and compacted soil that give the seed light and room.
Canada thistle and field bindweed deserve a mention because they are tough here. Both are perennials with deep, spreading root systems that shrug off a single pass. We plan repeat treatments for them and tell you up front that they take a season to beat.

Questions about this service
Why does weed control work better in fall in Casper?
Perennial weeds such as dandelion and thistle move energy down to their roots in September to survive winter. A product applied then travels with it and kills the root, not just the leaves. Spring treatments mostly burn the top and the plant regrows.
Will the weed control hurt my grass?
No. We use selective products that target broadleaf weeds and leave Kentucky bluegrass and fescue alone. Crabgrass products are chosen for cool-season lawns. Your technician notes any sensitive areas, such as new seed, before treating.
How soon can my kids and dog go back on the lawn?
Once the application has dried, usually a couple of hours. The exact window is written on your visit notes, and we are happy to time visits around your schedule.
Can you get rid of field bindweed?
Yes, but it takes repeat treatments, often over more than one season. Bindweed's roots run deep and resprout, so one pass thins it and the fall follow-ups do most of the work. Thickening the turf along edges and thin spots keeps it from taking over again.
Is a thick lawn really the best weed control?
It is the long-term answer. Weeds need light and open soil to start. A dense, well-fed lawn mowed at three inches or higher shades the soil, and crabgrass in particular struggles to get going. That is why our weed control and feeding programs work together.
How much do weed control services cost in Casper?
Weed control cost depends on lawn size, current weed pressure, and how many visits the season needs. We quote after seeing the lawn, with no contract required. Call TruGreen Casper at (307) 234-0077 and we'll inspect your yard and explain the plan.
How often should weed control be done on a Casper lawn?
A Casper lawn usually needs several weed control visits a season, starting with a pre-emergent in early spring and follow-ups through summer. Weeds emerge at different times, so one application won't cover them all. We set the schedule for your lawn. Call (307) 234-0077.
Is your weed and lawn pest control safe for my family?
Yes, our weed and lawn pest treatments are applied with your family in mind, and we tell you how long to stay off the lawn after each visit. Following that wait time keeps kids and pets safe. Your technician explains it at the visit. Call (307) 234-0077.
