Thatch is a layer of dead organic matter that settles in and around the base of your grass. When it gets thick it prevents water and fertiliser from soaking into the soil to reach the grass roots. To remove thatch, closely mow the lawn then rake vigorously. You can also hire specialist de-thatching equipment.
Aerate your lawn to allow air, water and nutrients to filter down to the grass roots. In most cases a garden fork will do the job or get your hands on lawn aeration equipment for big areas. After aeration, top dress with a thin layer of a highly organic compost mixture such as Seasol Lawn Top Dress Mix to replenish nutrients and to keep the holes created by the aerator open. If the lawn is uneven, use extra top dressing compost to help level out uneven areas.
Autumn is also the time for repair. This may involve sowing seed or planting runners to cover bare batches. Follow up repairs by applying Seasol Lawn + Soil Booster to the soil. Dig it in slightly to improve soil health as well as water and nutrient uptake. After resowing or planting runners, apply Seasol Lawn & Turf Starter to the lawn to aid seed germination and the rooting in of lawn runners. It will also help reduce transplant shock and aid lawn establishment.
Autumn can be a tricky season for watering as early autumn may still have hot days and should be treated like summer, while the cooler months will see a decrease in demand for extra water. The best approach is to check soil moisture levels and water as needed. A long deep watering once or twice a week, produces stronger lawn growth than shorter but more frequent watering.
As autumn progresses it can bring on windy days, which may dry out the soil. Once cooler conditions arrive they allow the lawn to recover from summer’s heat. Apply Seasol to your lawn every month throughout autumn to help give the lawn resilience for the winter ahead.
