Patchy Lawn Over Seeding

Patchy Lawn Over Seeding

Preparation

  1. Mow the lawn, with blades as low as possible - ideally 2.5cm high
  2. Use a rake or scarifier to break up and remove existing matted grass
  3. Using a fork, spike the lawn to create pockets for the seeds at a depth of 1.5cm. 

Sowing

  1. Divide area into manageable sections – ideally into square metres
  2. For overseeding sow at 25-35g per m²
  3. Shake pack to mix the seed
  4. Sow half the seed across the section from left to right. Then sow the other half from top to bottom. This will ensure even coverage
  5. After sowing, roll or tread in to get maximum seed to soil contact. Lightly water the overseeded area immediately

Aftercare

  1. Do not apply lawn fertiliser until the new seeds are established
  2. Try and keep the area moist but do not oversaturate
  3. Reduce the amount of traffic over the area and, if possible, use a net or garden fleece to protect from birds
  4. Try to remove weeds that appear within the area
  5. Lightly cut the overseeded area for the first time when the new grass is 5-8cm high
  6. For following cuts, lower the blades to about 2.5cm high try not to remove more than 1/3 of growth in one cut

Maintenance

  1. To maintain a lush looking lawn, apply a lawn fertiliser (once the new seeds are established) during spring, summer and autumn
  2. To thicken the lawn, ensure that you continue to over- seed patchy areas each year, or as necessary
