Pendulum AquaCap Herbicide can be applied in both spring and fall, depending on the weeds you are targeting. It is recommended that on cool season turf, pre-emergent applications be done in either mid to late March-May and/or August-November in the fall before the soil temperature reaches 55 degrees Fahrenheit. Please check out our Cool Season Lawn Schedule for information on when to apply products.
