FAQ:

Q: What is the best weed killer spray?

A: The claim that it is the best weed killer is corroborated by the University of Nebraska’s Department of Agromony, who, in 2005, performed a comparative study of all Glysophate type herbicides and found that Roundup topped the list with a 98 percent success rate.

Q: When to apply pre emergent weed preventer?

A: Apply a pre-emergent weed and feed in early spring to control the growth of crabgrass and germinating weeds. The best time to apply a pre-emergent is March in the southern half of Ohio and April for the northern half. These weeds begin to grow and spread once the soil temperature reaches 52 degrees Fahrenheit .

Q: When is the best time to spray for weeds?

A: The best time of day to spray for lawn weeds is when the temperature is between 50 and 85 degrees. Choose a day when the wind is calm and the sky is clear, with no threat of rain.

Q: Does spraying vinegar kill weeds?

A: White distilled vinegar can be used to kill weeds that grow in gardens, lawns and through concrete. The white distilled vinegar should be sprayed on the top of the weed. Gardeners should reapply the white vinegar on any new weed growth. Eventually the weed will starve and die.
