How to Regenerate the Lawn Before Winter

It is undeniable that a thick and well-kept lawn, a large green carpet, is preferable to a stripped one, with damaged areas and little grass. Today we see together the possible causes of these problems and the remedies to regenerate the lawn, to have it healthy and shiny.

Repair grassy areas damaged due to lack of light

The stripped areas of the lawn must be worked with a hoe to move the soil before sowing.

One of the causes of the failure of grass growth, and therefore of the appearance of stripped lawn areas, is the lack of light. The most common varieties of seeds used for the lawn need to receive direct light during the day in order to grow properly.

After first sowing, it may happen that the lawn does not grow uniformly, especially under trees, hedges or in shaded areas due to gazebos and buildings. If the lawn grows thinner, thin and yellowish in color, it may not be the most suitable variety for that position.

We shouldn’t underestimate tree roots. Even if we don’t see them, they extend far beyond the branches, which act as an umbrella when it rains.

In these cases we can choose between two solutions to regenerate the lawn: create a flower bed around the tree (which we can fill with decorative material such as pine bark), or sow a variety of shade-resistant grass.

The most suitable varieties of lawn for shady areas are Festuca, some specific types of Ray-Grass and Dichondra, a herbaceous that forms a carpet that resists very well even in low light situations.

Before buying the seeds of one of these varieties, check the manufacturer’s indications regarding the resistance to foot traffic and the irrigation needs.

As a general rule, a lawn located in a shaded area will appreciate a less frequent mowing: if left to grow, it will have more leaf surface to carry out the necessary photosynthesis.

Repair grassy areas damaged by pests, fungi or trampling

The appearance of sparse grass areas may depend on other reasons:

  • Presence of pests in the soil which causes the lawn to turn yellow. It is necessary to use a specific insecticide to eliminate them and subsequently regenerate the lawn.
  • The emergence of fungal infections caused by insufficient drainage or excess irrigation. We need to understand the origin of the problem in order to solve it. The sprinklers may not be synchronized and, by crossing each other, watering a specific area excessively. Other infections can occur due to the presence of felt and residues in the grass, which we can remove with scarification.
  • In both cases, it is advisable to remove the mowing remains using the suction function of the mower. In this way, we will prevent spores from reaching healthy lawn areas that could get sick.
  • In areas of frequent passage, the grass tends to compact due to the trampling. In the long run, thinned areas will appear, which will force us to sow again. In these situations, it can be useful to place stones, gravel or decorative flooring to define the path we usually cross.

How to repair thinning lawn areas step by step

Distribute the seeds horizontally and vertically so that the surface to be sown is completely covered.

  1. Stir the earth to decompress it. Add soil if you need to level it with the rest of the lawn.
  2. Distribute the seeds in two crossed steps, so that the surface is covered by the seeds.
  3. Cover with soil, then compact with your hand or the flat part of the rake.
  4. Water the areas sown abundantly during the following days to cause the seeds to germinate.
  5. Wait until they reach a height of 10 cm before cutting with the mower.

How to regenerate the lawn step by step

The cover was sown with potting soil and water abundantly.

  1. Cut the grass very short and then pass the scarified. In this way we eliminate the felt layer, allowing the seeds we will use to come into contact with the soil to germinate.
  2. Remove the felt layer with a rake or using the suction function of the mower.
  3. Distribute the seeds in two crossed steps, so that the surface is covered by the seeds.
  4. Cover the seeds with potting soil and make sure they remain in direct contact with the soil.
  5. Watering. The seeds require constant humidity until their germination, therefore it may be necessary to water 2 or 3 times a day.
  6. Wait for the lawn to reach a height of 10 cm to make the first cut.
  • The best time to perform any type of lawn sowing is in the spring or autumn. The rains and mild temperatures favor the germination of the seeds with which we will give new life, and we will be able to regenerate the lawn.
