The best way to have thick and colourful lawn in the spring is to start the preparations this autumn. One of the most common mistakes people commit is scheduling the preparations too late.
1. Remove leaves.
A lawn covered in yellow and orange may look beautiful, but it's unhealthy for your grass. Leaves cover the lawn from sunlight and trap moisture, which can cause the grass to become soggy. Rake as often as needed.
2. Continue trimming.
Grass growth continues until the first hard chill. So, don't stash the mower just yet. Keep the grass height at 2½ to 3 inches. If you allow it to grow for few more inches, it will be susceptible to cold-related diseases. If the grass is too short, it will hinder with its ability to endure the extreme temperatures.
3. Don't stop watering.
Just because the weather is cooler means your lawn needs less watering. Although there more rain and less evaporation during autumn, that may insufficient for the hydration requirements of your lawn. Keep the sprinklers running until before the hard frost.
4. Ensure Soil Aeration.
Soil becomes compacted overtime. Also, it can become thatched with layers of roots and debris, which can all block water, nutrient and oxygen absorption. Loosen the soil at least once a year for healthier plants. Use a core aerator to pull out plugs of earth. Do it before adding fertilizer.
5. Add quality fertilizer.
Just like humans, grass also needs some help. Fertilizers are nutrient boosters and you should add them to the lawn before it is exposed to harsh weather. doing so will help the grass service the cold and to bloom in the spring. Make sure to use quality fertilizer. It is also a good idea to consult an experienced gardener on which type of fertilizer suits your lawn best.
6. Spread some more seeds.
Overseed your turf while it is still warm. This prevents growth of weeds and covers bare spots in your lawn. But you should not just throw seeds onto the lawn and expect them to do all the work. make sure they are in complete contact with the soil and are well-hydrated.
