located in pacific northwest.....lotsa rain during winter
months....drought like conditions during summer when one wants a good
looking lawn.
Soil here is **** poor. It packs down and gets as hard as concrete. So
last week had a guy dethatch the lawn. Dethatching gets rid of the dead
layer which prevents nutrients from getting to the roots. This week he
will come back and aerate. Aeration is probly what lawn needed most.
The aeration machine takes plugs about 6 inches long from the soil. You
can leave them on top or rake them up. The reseed like crazy. Maybe this
method might help.
