Aerate

For best effects use a mechanical corer. This machine saves on time (and frustration!) and does a much better job of aerating the soil than can be achieved by hand. Mechanical corers are also preferable to the powered units, which punch cores out of the lawn and can cause the surrounding soil to crack. Consider sharing the cost, around $120 a day, with the neighbours.

 

Apply wetting agent

Watering the lawn with a wetting agent, such as Seasol Super Soil Wetter or eco-Hydrate, will make the most of what water your lawn receives over the warmer months. It will also increase the impact of fertiliser applications, and prevent surface runoff. Wetting agents should be applied once every six months.

 

Lime

Feeding the lawn season after season lowers the pH of the soil, making it increasingly acidic. To help bring it back to the right pH range, apply lime at a rate of 100g per square metre. This will help the grass absorb vital nutrients that can be ‘locked up’ by an acidic pH.

 

Feed

Now is the time to give your lawn the first of its four seasonal feeds. Apply a lawn food such as Grass Master, Sudden Impact for Lawns or Buffalo Booster to give the lawn an organic-based start to the growing season. Make sure to vary your fertilisers over the season, rather than sticking with just one kind. Specialised fertilisers can also be used which contain grub killers or weed killers.

 

Mowing

Mow the lawn a little and often for best results. Mowing once a week promotes even growth and a stronger lawn. Letting your lawn grow long, then slashing it down repeatedly, weakens the plants and allows weeds a chance to grow in the bald spots. Sharp blades on your mower are essential so that the leaves are cut rather than bludgeoned.

 

Weed control

A thick, lush lawn is the best defence against weeds. Most weeds can be controlled with the application of a selective broadleaf herbicide (Bin-die, Kleen Lawn etc). Be careful if treating buffalo; only use sprays approved for this purpose as buffalo can be harmed by incorrect application of herbicides.
