Answer:

When using Killzall Weed and Grass Killer, if the weed is actively growing (not just green), is not under cold stress or drought stress or recently mowed you should see results within 1-3 weeks depending on the type of plant. A second application may be needed after 4 weeks for very hard to kill plants (woody stemmed plants or vines).
