What’s the best way to do this? Do I need to wait until winter when they are dormant? 1 Answers 0 Vote Up Vote Down DeerGro Expert Staff answered 4 weeks ago You can spray clover in the rain with PlotStart. Since clover is hardy and the rain mostly washes the leaf surface off, you can get away with spraying PlotStart in the rain to avoid burning the leafs.
