Growing conditions can be made less favor- able by lightening the soil or other- wise improving drainage, especially in shady areas. Heavy, constant shade should be lightened as well where possible. Shady areas should be planted with turfgrass species which do well in the shade and which will provide maximum competition to weed species which invade shady areas.
