The association truck is not the plant
Dallisgrass in Arlington Bermuda does not wait for the HOA spray Saturday. That clump is a perennial grass in the turf you wanted to keep. A calendar pass aimed at winter annuals or a generic "weed day" often hits when the dallisgrass is stressed, mowed off, or when Bermuda is too off-color to tolerate the mix. SureGuard wants the plant named and actively growing before we pick a window, not a board date.
Photograph the clump, the wide pattern, and whether it sits in a wet corner or a thin, hot strip. Grand Prairie and Arlington share clay. They do not share your clump.
Do not mow the evidence the morning of the truck
Seed heads and leaf width are how we separate dallisgrass from crabgrass and from Bermuda itself. If the HOA mows Wednesday and sprays Saturday, we may miss the ID and still mark the stand. Tell us the mow day. We would rather delay a week than burn a lawn for a meeting agenda.
Dead dallisgrass leaves a hole. Holes grow the next flush. The ticket should say whether we are cleaning plants, repairing Bermuda, or both, and who keeps kids off the rectangle.
Heat and drought change the window
Post-emergent on toasted clumps in 100 degree weather often fails. We wait for a recovery day even if the association wanted it done "this month." Pre-emergent will not erase established dallisgrass. If you want winter rye, say so. That goal fights some summer products.
Use contact with city, photos, and the last HOA spray date if you have it. More notes are on the blog.
Closeout names the clump, not the Saturday
What we treated, what we left, and whether a hole needs Bermuda repair. Next year we compare that map instead of repeating the association calendar.
