We're sorry to read about your disappointment with Ortho Groundclear Weed & Grass Killer and appreciate your feedback. This product is not systemic but kills off the top of weeds thoroughly treated at time of application. For annual weeds, especially if young, this will typically kill them. Also if the weed is mature, no matter what weed, it will be more difficult to control. Some harder to control or mature weeds will need multiple applications. To get the best results plant leaves must be thoroughly and uniformly covered with the spray solution. For best results apply when temperatures are between 60-85 degrees.

After disconnecting the red plug from the cap soak the spray tip/nozzle in warm soapy water. This may dislodge any crystallized matter. The sprayer tip can be readily pulled off and snapped back on after cleaning. Batteries have a shelf life that will last through approximately two 1.33 bottles. It is possible that the batteries need to be replaced. The unit holds either 3 or 4 Double-A (AA) batteries (depends on the wand version). Replace the old batteries with fresh ones to see if that fixes the spraying issue. If the sprayer motor is running and all of the above troubleshooting has been completed, the sprayer may need to be re-primed. To re-prime, place the container above the wand (either holding it above or setting it on something) and spray for 30 seconds in an area where the product can safely be dispensed.
