Top 10 Best Herbicide for Asiatic Dayflower in Ornamental Beds

Its ready‑to‑spray design makes it easy for homeowners to apply along paths, edging, and garden beds. The formula becomes rainproof quickly so it stays active on foliage.
Because it is designed to kill broadleaf weeds while sparing desirable grasses, careful spot application near ornamental beds helps suppress dayflower without excessive non‑target damage.

Ortho GroundClear Weed & Grass Killer Ready‑To‑Use is a broad spectrum weed killer that controls Asiatic dayflower foliage when applied to weeds directly. Its ready‑to‑use spray bottle simplifies targeted applications near delicate ornamentals. Focused spraying reduces drift and limits non‑target exposure.
The product’s systemic formula ensures active ingredients move into weed roots for longer‑lasting control. Apply only to visible weed foliage, and shield adjacent ornamental plants with cardboard or physical barriers during application.

Use a handheld sprayer or shielded application to protect desirable ornamentals. Spot treat dayflower patches and integrate with manual removal for best performance. This product fits well in small garden bed weed management routines.

10. Green Gobbler Vinegar Weed & Grass Killer – Best Natural Contact Herbicide

Green Gobbler works best on young weeds and smaller patches. Always avoid spraying desirable plants; use shields or cardboard to protect ornamentals during application. Multiple applications may be needed since contact herbicides do not travel to roots.
