Rake up leaves and debris (but wait until the ground is dry to avoid making the ground uneven).
Aerate to liberate.
If you live in the south or southwest, increase absorption and percolation by treating your soil with exiGrow to liberate the hardened mineral salts. If you have more acidic soil, consider traditional core aeration.
Get them before they get you.
Prevent weeds by applying a pre-emergent herbicide (you’ll want to reapply in about 3 months).
Feed the beast.
Apply slow-release fertilizers every 6-8 weeks beginning in late spring when the soil temperature is above 55°. Consider 20-5-10 (20% nitrogen, 5% phosphate, 10% potassium), but check with your local garden center for the proper mix for your area and grass type.
Seed the bald spots.
Check with your local garden center for the best seed to fill in those bare areas. Hard rake the area to loosen the soil, evenly spread the seed, cover with hay to prevent wind or creatures disturbing the seeds and new sprouts, and water daily for at least a week.
Just a bit off the top.
Give your lawn a trim — but only the top 1/3.
Relax and Enjoy
Follow these steps as you enter spring to create a healthy, green lawn you can enjoy the rest of the year.
