Spring Lawn Prep
Rake up leaves and debris (but wait until the ground is dry to avoid making it uneven).
Aerate to Liberate
If you live in the western half of the US, increase absorption and percolation by treating your soil with exiGrow to liberate the hardened mineral salts. If you have acidic soil, consider traditional core aeration, Humic Organic Pellets, and lime to raise pH.
Get Them Before They Get You
Prevent weeds by applying a pre-emergent herbicide (you’ll want to reapply in about 3 months).
Take Your Vitamins
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.
Cover 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. But first, be sure to clean your mower and sharpen the blade.
