Roots Grow in the Gaps

Compacted soil starves roots of air and water. What aeration actually does underground, how to tell if your lawn needs it, and why hollow tining beats spiking.

About this episode

Grass roots need air as much as they need water, and compacted soil has neither. This episode looks at what compaction does to a lawn over years of foot traffic and rain, why the symptoms get blamed on everything else, and the simple screwdriver test that tells you whether your soil has a problem.

We then compare the methods. Hollow tine aeration removes plugs of soil and creates real space for roots; spiking with a fork or a rolling spiker mostly pushes soil sideways and can make compaction worse. We finish with how often a typical lawn needs it.
