With just a little bit of work, you can overhaul your lawn's health to help it thrive in the winter months. Start with a thorough raking to open the ground and expose the soil so new seeds can germinate. Aerate if necessary, to provide air, water and nutrients to the grass roots. Aerating is especially necessary for compact heavy soils. Next, level the lawn by covering the lowest areas with new soil. Overseed bare patches in an established lawn; your grass will be more lush, and moss and weeds won't have as much room to take over. A fall feeding is one of the most important of the year. Apply a fall or winter fertilizer to encourage nice green grass and healthy root development. An advantage to doing this in the winter is that nature provides enough water to germinate the seeds.
Once you have finished with your garden tools and equipment for the season, give them a good cleaning so they’ll last a long time. Sharpen pruners, clean up shovels and other tools using emery cloth, apply a light coating of oil, wipe, and keep them in a dry place.
