The Ultimate Lawn Care Calendar: Seasonal Tasks for a Healthy Green Lawn Feb 21, 2026

Let's dive into the essential seasonal tasks:

Spring is the season of renewal and regrowth, making it the perfect time to revive your lawn after the dormant winter months. Start by raking away any debris such as leaves, sticks, or dead grass, allowing new grass to push through. Aeration is crucial in spring, as it reduces soil compaction and enhances nutrient absorption. Applying a quality pre-emergent herbicide can protect your lawn from weeds before they have a chance to sprout.

Fertilization is another key spring task. Choose a balanced fertilizer that supplies the necessary nutrients to encourage robust growth. As temperatures start to rise, it's essential to begin watering your lawn consistently. Aim for deep and infrequent watering to promote deep root growth.

Summer can be taxing on your lawn, with high temperatures and increased foot traffic. Regular mowing is critical; however, adjust your mower blades to a higher setting to prevent stressing the grass. Keep an eye out for signs of drought stress, such as dull or wilted grass. Increase your watering frequency during heatwaves, ensuring your lawn receives at least an inch of water per week.

Weed control remains important during the summer months. Spot treat weeds as they appear, using a post-emergent herbicide. Summer is also the time to monitor for lawn pests such as grubs and chinch bugs. Implement proper pest control measures to preserve the health of your lawn.

As autumn arrives, it's time to prepare your lawn for the colder months. Fall aeration is crucial, as it provides better water and nutrient access to the roots. Overseeding is another vital task during this season. By introducing new seed, you encourage thicker growth and repair any bare patches.

Apply a high-potassium fertilizer in the fall to strengthen the grass roots for winter. Regularly rake fallen leaves to prevent them from smothering the grass and creating bare spots. Also, scale back on watering as the temperatures cool, aligning with natural rainfall patterns.

Winter is a resting phase for your lawn, but it doesn't mean neglect. Ensure you clear any debris, furniture, or toys that may obstruct the lawn and hinder its growth come spring. Take advantage of the slower growth period to maintain your lawnmower and tools, preparing them for busy seasons ahead. While snow cover can protect your lawn, be wary of using salt-based de-icers on paths and driveways as they can damage grass edges. Opt for lawn-friendly alternatives instead.
