Soil is the key to establishing a good lawn and the health of the soil dictates the health of the lawn. If you don’t have the luxury of starting from scratch or have inherited a lawn in dire need of love, a top dressing of lawn compost such as Seasol Lawn Top Dress Mix applied throughout the warm months improves the soil and its waterholding capacity, which in turn saves water. Applying Seasol Liquid Compost hose-on, a no dig option, also helps revitalise soil as it helps improve the soil structure, increasing microbial and worm activity as well as moisture and nutrient retention.
Weeds continue to grow through summer so keep an eye on them and remove them before they flower and seed. Remove them by hand in the cool of the day, either early in the morning or in the evening to avoid the heat of the day.
Thatch is a layer of dead organic matter that settles in and around the base of lawn. When it becomes thick it prevents water and fertiliser from soaking into the soil where the roots are growing. To remove thatch, mow your lawn so it is closely cropped then rake the lawn vigorously using a metal rake. You can also hire specialist de-thatching equipment.
Aerating the soil also allows 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 some lawn aeration equipment for big areas. Top dress the lawn with a thin layer of highly organic compost mixture such as Seasol Lawn Top Dress Mix to replenish nutrients and fill the holes opened by the aeration process.
Autumn is also the time to set the lawn up for the winter ahead by over sowing with a cool season lawn seed mix of grasses that grow through winter to help the lawn stay green as temperatures fall. You can also use seed or rooted runners to repair bare patches that have formed over summer. Before repairing the lawn apply Seasol Lawn + Soil Booster to the bare soil and dig in slightly to improve soil health, water and nutrient uptake. After resowing or planting runners, apply Seasol Lawn & Turf Starter to the lawn. This aids seed germination and helps reduce transplant shock, aiding lawn establishment.
Winter is all about improving soil health, so apply Seasol Lawn + Soil Booster over the lawn to help to improve soil structure and increase worm and microbial activity. It also helps to improve soil moisture and plant nutrient uptake. Apply 100 grams per square metre of lawn via hand or lawn spreader and water it in thoroughly after application.
