Do you need to water in? What if a rain comes in the next 12hrs?
Amdro Pro does not need to be watered in. According to the Amdro Pro product label, " Amdro Pro may remain effective for up to 10 weeks (or longer) depending on environmental factors. Excessively wet (prolonged high humidity, frequent and prolonged rainfall, and heavy mists) conditions may reduce the effectiveness of Amdro Pro." You should not apply the granules withing 12 hours of rain fall.
