How long before the weeds die?

Weed control is dependent on the temperature. A general rule of thumb is the colder the evening temperature the longer it takes for weeds to die.

Cold evening temperatures (rounds 1, 2, 3, and 7) – may take 14 to 21 days to see results.

Warm evening temperatures (rounds 4, 5, and 6) – should show results within 7-10 days.
