Too much water, very rocky ground, seeding too deep… there are many possible reasons for a lawn that is thin or not growing properly. Discover here the causes and the solutions to consider in order to enjoy a uniform and green lawn.

Grass Not Growing: Possible Causes

A freshly sown lawn can sometimes hold unpleasant surprises. In some cases, the seeds never seem to want to germinate, or do not grow evenly, leaving bare patches of lawn here and there.

There are five main possible causes for this phenomenon:

  • Too deep sowing/ When grass seeds are buried too deeply, the lack of sun delays their germination. To germinate, the seeds must be sown on the surface.
  • Too early or too late sowing. Spring and autumn offer the best conditions for sowing a lawn. The seed germination rate is indeed much higher when temperatures are between 10 and 23°C.
  • Too stony. Ground Land that has recently undergone masonry work is often filled with rubble. These then prevent the seeds from growing.
  • Too much water. Be careful not to overwater your grass seedlings . A lawn that does not grow can be the result of watering too often or too much.
  • Applying fertilizer prematurely. A yellowing lawn is often due to applying fertilizer too early. Always wait several weeks before applying fertilizer to young grass seedlings.

Solutions to a lawn that does not grow

Despite your first disappointments, do not be discouraged! Solutions exist to achieve a lawn that grows evenly.
Be patient first. Indeed, be aware that the germination of grass seeds takes an average of three weeks. So wait at least a good month before panicking.

As we have seen, drowning your seedlings under gallons of water can ruin your lawn. Avoid watering the seeds every day. A weekly water supply is more than enough here.

If your lawn is thinning in places , the rain (or your sloping ground) may have moved the seeds. These have thus concentrated in certain places, deserting the other surfaces.

To remedy :

  1. reline bare surfaces;
  2. spread a thin layer of potting soil over the relining;
  3. pass the roller over the assembly;
  4. water in fine rain.

Finally, if your efforts do not bear fruit and your grass still refuses to grow after a month, reseed it entirely in the spring or fall.

  1. Start by pulling the weeds.
  2. Loosen and level the soil.
  3. Opt for a lawn that is well suited to your land (slope, exposure, pH, etc.).
  4. Sow the seeds broadcast and on the surface.
  5. Push them lightly into the ground using a roller.
  6. Water in fine rain once a week.
