Sow grass seed
Done now it has time to grow strong before winter
September is an ideal time to sow grass seed while the soil temperature is still warm and hopefully moistened by the first of the autumn rains. Sowing now can be done to create a new lawn from scratch or to repair damaged areas in an existing patch.
The main advantage of sowing now is seed has plenty of time to germinate and grow before the onset of winter. As well as producing plenty of top growth, more importantly the new grass will be able to establish a strong root system to get it through the colder months. Come spring the lawn will grow away to produce a thick, healthy lawn.
When creating a new lawn, the area needs preparing properly to remove any perennial weeds. This can be done by thoroughly forking them out, or you can spot treat with weedkiller. The ground can then be cultivated by forking the soil over or rotavating, before raking, treading and a final rake to produce a firm, fine bed to sow seed on. When repairing worn areas, use a fork or rake to loosen the surface where the grass is thin or damaged to expose some soil to sow the grass seed onto. Sown now in moist, warm soil, the seed should be through in 10-14 days.
