How long after using Killzall should I start seeing results?
If the plant 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).
For best results, apply on a warm sunny day when daytime temperatures are above 60°F.
Weed control is accelerated by warm sunny weather. For best results, reapply the product
if rainfall or watering occurs within 24 hours after application.
