Why Is My Grass Clumpy

One possible reason why your grass is growing in clumps is because the soil is too compact. If the soil is compact and hard, it may restrict its ability to absorb moisture. And when soil becomes dry, grass and other plant life may cease to thrive. You can combat this problem, however, by aerating your lawn.
