Spring is finally here on the West Coast and it's time to consider lawn aeration with lime application. Aeration allows more water and oxygen to reach the root zone; and lime should, in theory, lower the soil pH levels.
If you don't do anything to your lawn, definitely aerate it once a year.
If your lawn is small, consider using a hand-aerator tool. If your lawn is larger, renting a machine is the way to go; or hiring a professional landscaper.
