Replanting windows vary widely by product. Some descriptions allow replanting ornamental flowers, trees and shrubs within 1 day or about 5 days, while others require waiting longer—one product lists up to 4 months before planting sod or seed. Always follow the specific product label for the correct waiting period for the plants you intend to put in.

Coverage varies a lot by product and formulation. Descriptions list ranges from about 224 sq ft up to 7,500 sq ft per container, while some refill bottles report coverage in counts (for example, up to ~400 weeds per 64 oz refill). Check the product label for the exact coverage and application rate for your formulation and desired dilution.

Many descriptions and user notes indicate that many formulations are non‑selective and will kill lawn grass if sprayed on turf. Several products are explicitly not intended for use on lawns and should be applied only where you want vegetation removed. Read the label for use‑site restrictions and avoid drift or overspray onto grass.

Descriptions report rainproof/dry‑time windows of roughly 15 to 30 minutes before rain or watering is unlikely to wash away effectiveness. Exact rainfast times vary by product—follow the label for specific timing and reapplication guidance.

Product descriptions list many use sites including hardscapes (driveways, sidewalks, patios, pavers, cracks and crevices) and landscaped areas (flower beds, mulch beds, around fences, trees and shrubs), plus gravel areas. Always check the label for approved surfaces and restrictions before applying.

Timing depends on the formula: some contact or plant‑based products show effects in about 20 minutes to an hour, many report visible wilting within a few hours, and complete die‑back can take 1–2 weeks. Persistent weeds may require repeat applications every 2–3 weeks according to product directions.
