|Our lawn is about 4 years old. Our front lawn is doing well but he back lawn is not. It looks like the runners just run along the top. Each year we have fed the lawn with weed and feed but it has just not gotten thick. Could it need more dirt and what kind of dirt. What about putting sand on top? Our ground is very sticky, kind of like play dough.

|I think if you aerate your lawn you'll reduce the compaction which will help loosen it and help it hold more moisture, which will encourage deep rooting. This, in turn, will help your lawn tolerate droughty summer conditions. A core aerator will remove one inch by three inch plugs from the lawn. Leave the plugs on the lawn and they will dissolve in rain or water from the sprinklers. After aerating spread a thin layer of sand or compost over the area and water it in well. The sand or compost plus the soil from the plugs will work their way down into the holes left by the plugs. You can then overseed your lawn if you'd like.
