10. Worm Casts

The casts left by worms on the lawn surface are an unsightly mess. They should be brushed off when dry or otherwise they will be smeared during mowing, and this kills the grass underneath them, leaving bare soil for weeds to germinate in. Don't overwater a lawn since worms love moist conditions. Use a switch regularly to remove excess moisture.
