Complete Guide to Lawn Care

An expanse of green grass is one of the great traditions of the typical Aussie garden. It's hard to imagine a home in the suburbs without the 'show' lawn in front and the family-sized cricket pitch or footy field out the back.

From the quarter acre block to the inner city terrace courtyard, they’ve long been a source of great pleasure and, let's be honest, pride.

Taking care of your lawn and keeping it looking its best is easy.

Here’s our simple guide to get you started.

  • How long should your grass be?
    Go for ‘foot feel’. Trim your grass so it feels comfortable with a little bit of spring under bare feet.

  • Never mow too low.
    You may think you’re getting the jump on growth, but the grass will most probably grow back faster, may develop patchiness and ultimately you’ll damage your lawn.

  • Avoid watering immediately before or after mowing.

  • Mow in the morning or afternoon.
    Avoid the hottest times of day to minimise lawn stress.

  • A quality cut comes from a well maintained mower.
    Service your mower regularly. Ensure the disc and under-deck are kept clean, the blades are clean and sharp and the engine oil and spark plug are changed as per the service book.

  • Empty the catcher frequently.
    Don't allow the catcher to fill right up. Empty it before it is completely full, otherwise your mower will sink in with the extra weight giving the grass an uneven cut.

light-bulb-icon@2x.png Mulch mowing - what is it?

A mulching mower uses a modified disc and blade system that cuts the grass initially and then recuts the clippings to a super-fine state before forcefully blowing them back down on to the lawn. When mowing in mulching mode, the catcher is not used.

The fine clippings (now mulch) break down, adding valuable nutrients and organic matter to your lawn and soil. The layer also protects against rapid drying and potential sunburn over Summer.

Mulch mow isn't always the best way to go. There are times you should mow with the catcher on:

  • When your grass is damp
  •  If there will be lots of foot traffic after mowing - the clippings can get picked up on shoes and feet.
  • When your grass is too long.
  • Through cool, damp months when the clippings may not break down fast enough, giving rise to possible fungal problems.

light-bulb-icon@2x.png How and when to water

A healthy lawn that is regularly fed, maintained and mown will be able to tolerate dry conditions quite well. However, there will always be times when it needs a bit of extra water.

The key to good watering is to ensure it is both effective and efficient.

how-when-to-water.jpg
  • Watering early in the day is best. If you water in the evening, the grass will stay wet overnight, creating humidity which could lead to the spread of fungal diseases.
  • Don’t water when it’s windy.
  • Aim for deeper moisture penetration by watering less often, slower and for longer to encourage deeper roots.
  • If you find nothing soaks in when you water, apply Lawn Builder + Wetting Agent or Everydrop Liquid Soil Wetter
  • When using a sprinkler, fit a mechanical tap timer to turn the tap off after a pre-determined time so you don't waste water.
  • Invest in a quality lawn sprinkler with adjustable patterns so you are not watering paths and driveways.

Top Tip 

Regular mulch-mowing will improve the ability of your lawn to retain moisture. The mulched clippings act like micro-mulch, building up the moisture retaining ability of the soil and reducing both the frequency and duration of watering.

light-bulb-icon@2x.png The importance of fertilising

importance-of-feeding.jpg

Fertilising your lawn is quite possibly the easiest task you need to do to gain a perfect lawn.

Apply a Lawn Builder Slow Release fertiliser and your lawn will not only become greener but it will also be tougher and more able to resist everything from dry conditions to weed invasion.

Regular feeding is so easy and has all these benefits, yet surprisingly as few as one in four homeowners fertilise their lawns!

If you only perform one maintenance task, aside from mowing, then make it fertilising. It will take less than 10 minutes for the average lawn and will reward you for months.

light-bulb-icon@2x.png Fertilising Tips

fertilising-tips.jpg
  • Before fertilising, rake the lawn to remove leaves and other debris.
  • Allow at least two days after mowing before fertilising.
  • Wait about a week after application before you mow - and leave the catcher off the first time (the fertiliser could all end up in it if it's left on!)
  • Don’t water before applying any lawn food. Doing so could lead to fertiliser being unevenly distributed.
  • Select the Lawn Builder Slow Release fertiliser that’s right for your lawn variety and the time of year.
  • Read ALL the instructions on the bag and make sure you do not apply any heavier than the rate recommended. Over application may result in burning of the grass.
  • Best results are achieved by feeding three times a year – early Spring, early Summer (before it gets too hot) and mid to late Autumn.
  • If you only feed once a year, do so in late Spring to early Summer.
  • Even coverage is important so ALWAYS use a Scotts spreader (handheld or wheeled).
  • Follow the directions on the pack for when and how to water after fertilising.
  • Don't store an opened bag of lawn food for more than 6 months.

exclamation-icon@2x.png Two in one - fast greening and slow release fertilising

Not that long ago you had to make a choice – long-term feeding or fast greening.

Trying to achieve both risked damaging your lawn and all manner of potential environmental problems, such as nutrient runoff, overloading the soil with nutrients, damaging the soil chemistry and altering the pH. But not anymore!

Lawn Builder Extreme Green lets you have the best of both worlds. You can fertilise on Wednesday, your lawn will be lush green by the time your guests arrive for the barbie on Saturday and best of all, you won’t need to feed again for three months.

You will need:

Step 1

Calculate amount of fertiliser you’ll need by measuring your lawn in square metres (one large stride = 1 metre approx). Read the instructions on the bag to see how many grams per square metre to apply, then add the appropriate quantity to spreader hopper. Set the spreader to the correct aperture using the spreader setter information on the bag.

Step 2

Walk the full area of your lawn while spreading fertiliser, following a pattern that allows slight overlap on the edges of the spread. It's recommended you apply half the fertiliser in a north-south direction over the entire area and the other half in an east-west direction, to obtain even coverage.

Tip – if you’re using a hand-held spreader you may find it easier to walk backwards.

Step 3

Check the bag for more detailed information about when to water but, as a general guide, thoroughly water your lawn immediately after spreading to activate the quick greening component or better still time your application for just before rain if it is forecast.

exclamation-icon@2x.png The importance of aeration

Even with just normal foot traffic, the soil under your lawn can become compacted, making it hard for grass roots to penetrate and breathe. It also becomes more difficult to get nutrients and water down to the root zone.

Compaction problems typically appear as worn areas that are slow to repair or spreading dead patches. All round poor performance of the lawn may also be an indicator. Fixing compaction problems is pretty simple.

You will need:

Step 1

Using a metal tined lawn or leaf rake, vigorously rake the lawn to remove all dead grass and other material.

Step 2

For smaller areas: Grab a sturdy garden fork and push it around 5 cm into the soil then gently rock back and forth to open the holes up. Continue over the whole lawn area at around 10cm spacings.

Step 2

For larger lawns: Hire a spiked lawn roller, part fill it with water and then roll over the whole lawn - you’ll find it easier to drag than push.

Step 3

Spread washed river sand or Lawn Builder Topdress Mix over the area and then, if not previously applied, spread an appropriate Lawn Builder lawn fertiliser. Rake this mix in well before watering.
