What is the key to getting Momentum Premium W&F w/ Polyvex to work? I used a broadcast spreader at the specified rate early in the morning when the dew as still heavy, but have yet to see much of an impact on the weeds. I am looking to clear up clover, violets, dandi's and such. When is it safe to reapply? Did Lesco lead me astray? Should I be using something else?
