The weather is warming up in Denver and April is underway, so it is time to start thinking about tending to your lawn.

Tony Hahn visited 9NEWS to spread the word that aeration is one of the most important things you can do for your lawn. Hahn says the simple step is critical for landscapes in Colorado.

Aerating the lawn creates openings for nutrients and water to penetrate the soil, improves soil structure and helps create growth pockets for new roots. Hahn recommends aerating on a regular basis, once or twice a year.
