6. How do I overseed my lawn?
How to over seed your lawn:
- Mow the lawn to approx 25mm.(1")
- Use a spring tine rake to break up and remove the layer of dead matted grass known as thatch. Dependent on the depth of thatch on a lawn this process (scarification) may require a powered scarifier, which can be hired from most hire shops.
- Using a garden fork, spike the lawn to a depth of approx. 150mm (6") at 300mm (12") intervals.
- If the lawn has not been fed in the last 4 months, apply Rolawn Spring or Autumn Lawn Food, depending on the time of year, 4 or 5 days before sowing
- Sow the seed evenly across the lawn.
- Rolawn Lawn Seed can be mixed with Rolawn Lawn Top Dressing and applied to the lawn jointly.
- The seeded area must be kept moist, therefore, water your lawn after 2 or 3 days of sowing if no rain has fallen.
- Specific bare patches can be sown without treating the whole lawn. Apply the same procedure as above, but use sowing rates as for a new lawn - Medallion® Premium Lawn Seed at 35g per square metre and Minster Pro™ Ornamental Lawn Seed at 38g per square metre.
- To protect specific areas from birds consider covering with netting or garden fleece. This should be removed when new shoots start to come through the soil.
- Try to keep traffic on a freshly over seeded lawn to a minimum for 7 to 21 days.
- Raise mowing heights to approximately 50mm (2") for the initial 2 or 3 cuts, then reduce down to 25mm (1") over the next 2 or 3 cuts. Never remove more than ⅓ of the grass blade length at any one time, on new sowings ideally never more than ¼.
