Step 1 - Clear DebrisPick up any branches and twigs, then remove fallen leaves with a leaf blower.
Step 2 - Mow LowCut your grass to a height of 2-1/2 inches and leave the clippings on the lawn. This returns up to 25% of nitrogen back into the soil. Remember that lawns should be put to rest over winter at the same height they are maintained over summer. Taller grass ensures a deeper root. Cutting too short can make the lawn more susceptible to winter damage.
Step 3 - AerateLayers of dead grass, leaves and other organic matter, known as thatch, can build up on the surface of the soil, blocking drainage, encouraging moss, harboring fungal diseases, and preventing the strong growth of grass. Dethatch to aerate your turf so essential nutrients can reach your soil.
Step 4 - Top-DressA nice, thick lawn requires healthy soil as its base. Since many home lawns have poor quality soil, top dressing becomes even more important. Top dressing is simply a way of adding organic material and restoring the balance to home lawns, building better soil and increasing soil flora. Spread the soil using something flat, like the back side of a heavy garden rake, working it into aeration holes and covering low spots. Make sure the top-dressing is no more than 1” deep (preferably ½” or less) over the existing grass.
Keep working the mixture until your grass peeks through and the depth is even.
