Lawn Care 101: What is Lawn Dethatching & Aeration?
Dethatching is the removal of thatch, which is layers combined with dead turf tissues, roots and stems that accumulate over time between the surface soil and grass. In order to get more oxygen to the soil, it's important to dethatch then these when thatch gets too thick. Aeration is the process of punching holes into the earth for water, oxygen and nutrients to penetrate the soil and break up any thatch. By loosening compacted soil, this will ensure healthy plant and lawn growth.
You can test for thickness by running your fingers through visible thatch layers or measuring them. Your lawn will also feel a bit bouncy when if the thatch is getting unruly. Make sure to dethatch in cool-season grass during the fall and warm-season grass during early spring. A special dethatching rake works on a small lawn, but consider using a dethatcher machine or tractor attachment for a larger yard. A dethatcher's tines slice through the turf vertically, and using crisscross patterns help loosen up the turf before removal.
