Occasionally we apply products that have to be watered in to the soil. Spraying first thing in the morning doesn't allow me to get the required amount of water needed to push this product into the soil. With golfers starting at 7:30, there would be a good chance of them getting wet, so it makes since to spray at night. We installed LED lights to the sprayer making it much easier to see. While I was spraying greens, I noticed a pair of bats mating.
