Mechanical aeration provides an excellent, and probably the only, means of correcting or alleviating soil compaction which may be quite serious on many lawn areas. Compaction occurs primarily in the surface area of the lawn. A compacted layer as thin as ¼ to ½ inch can greatly impede water infiltration, nutrient penetration, and gaseous exchange between the soil and the atmosphere. Compaction of this type in the surface layer of soil can be corrected or reduced by the use of suitable aerating equipment.
Summer annual grasses continue to be pervasive weed problems in many turfgrass areas throughout Pennsylvania. The most common summer annual grasses in turf include crabgrasses (Digitaria spp.), goosegrass (Eleusine indica), foxtails (Setariaspp.), and barnyardgrass (Echinochloa crusgalli). Satisfactory control of these weeds can be obtained by cultural and chemical methods, provided the life cycle of the plant is understood.
Damping-off diseases occur as seed rots and blights of seedlings. This disease seldom occurs on grass planted in early fall or early spring.
The cause of turfgrass damage is often difficult to determine if considerable time has elapsed between damage and diagnosis. Damage is often blamed on disease or insects when there is no sound basis for such a diagnosis.
Successful management of home lawns depends on proper selection and management of turfgrasses. To obtain optimum performance from your lawn it is important to employ the appropriate management practices at the correct times of year.
Moss is one of the most persistent and annoying weeds that occurs in home lawns.
