how to take care of lawn in summer

It's no secret that Australia endures some of the harshest heat in the world. We're lucky enough, though, that when it's hot, we can retreat inside under the airconditioner or spend hours in the pool or at the beach for respite. Our lawns, on the other hand, have to endure severe weather, often resulting in dry soil and discoloured grass, which can cause an array of other gardening issues.

There are ways around this, though, and we at Bulka Bag Man have developed a summer lawn care schedule to help you keep your lawn lush and green all summer long.


A Three-Month Schedule For a Happy, Healthy Lawn

Believe it or not, you should start planning your summer lawn care schedule at the tail-end of spring, ensuring you have all the products and tools needed to maintain your lawn. In Australia, summer runs from December right through to February, so we recommend stocking up on the things you need before then, but more on that later.

Let's jump into what you should do to keep your lawn thriving all summer.


The start of summer is really where you need to put in the hard yards. A big effort in the beginning makes for little maintenance later. Let's talk about how to take care of your lawn in December.


Fertilisers encourage a healthy, happy, and pest-free lawn. We recommend top-dressing your lawn at the very start of summer (some people even start at the end of spring), followed by a good feeding. Lawns lose a lot of nutrients during spring, so feeding your lawn with a decent fertiliser early on in summer restores much-needed nutrients lost to springtime bloom. For top results, try Gro Turf Fertiliser, a professional fertiliser that encourages rapid and healthy growth.

Water Often

Your lawn needs a lot of water in the hotter months. We recommend deep watering your lawn at least three times a week to ensure it stays hydrated. If you've had a bit of rain in your area, you'll need to water less frequently. The opposite goes for areas experiencing dry spells. In this case, you'll have to water more often. The key is to not let your lawn get too wet or too dry. If the soil is damp after watering, you've done your job.

Lawn drying out too quickly? Try a wetting agent to encourage moisture.

Mow Regularly

You want to keep this up all summer, but particularly in December, as your lawn needs a little time to climatise to the summer heat.

It's important not to let your lawn get too long, and if you're watering it properly (that, coupled with regular sun), it will grow relatively quickly. As a standard rule of thumb, we recommend keeping your lawn between 3-7cm during summer.


Woo hoo, you're halfway! How's your lawn looking? Are you chuffed with it? Let's get started with January.


It's hot, so it's no secret that you have to keep your lawn hydrated in January, too. If you put in the hard yards last month, though, your lawn should require less watering. Although this is subject to location and weather conditions, so just continue doing what you're doing and adjust your water routine accordingly.

Wetting Agent

Evaporation rates are higher in summer, so we recommend applying a wetting agent at the start of January. Doing so will help prevent runoff and retain moisture in your soil for longer.

Monitor for Pests and Disease

Bugs, insects, and other pests love the heat. Be sure to monitor your lawn and garden for unwanted critters and diseases, and apply sprays and other insecticides to prevent an infestation.


When it comes to late summer lawn care, we recommend the following:

Water, Water, Water

You should be a pro at this now! Continue with your regular water routine, making adjustments where necessary. Save water by giving your lawn a drink in the morning, and apply a wetting agent if the lawn needs it.

NOTE: Wetting agents should only be applied once a month.

Pro Summer Lawn Maintenance Tips

Now you've got the basics down pat, here are some further tips to really help your lawn flourish this summer.


Be careful not to mow your lawn too short, as doing so can damage the grass and encourage weed growth. Instead, raise your mower blades and cut the leaf’s height by 1/3. This keeps the grass short enough for aeration but long enough to retain moisture in the soil.


Remember: fertilising earlier helps your lawn thrive. However, different fertilisers are suitable for different lawns. Learn about your grass type and find an appropriate food that'll help sustain your lawn throughout summer.

Weed Watch

Weeds love warm weather and humidity (Queensland, we're looking at you). Monitor your lawn for weed growth and remove them accordingly, preferably by hand if you can. It's also worth investing in some heat-safe weed control products, like our Bow and Arrow Herbicide.

Pest Control

Imagine putting in all that effort just to have a nasty little critter soil your hard work. Do some research and find out which pests and diseases are prominent in your area and lawn type. Doing so will help you mitigate an infestation.

One of the most common pests in Australia is lawn grubs. These nasty insects thrive in summer, with their larvae hatching into various other bug species that can damage your lawn and garden. You can counter these bad boys using Acelepryn and other insecticides. But get in early. You want to nip them in the bud before they become an even bigger problem.  

Signs of Pests and Disease

Not sure if your lawn is under attack? Here are some telltale signs:

  • Increased bird activity
  • Brown patches
  • Spongy lawn texture
  • Irregular turf coverage
  • Rust
  • Signs of mould


You read the schedule. You know you should water your lawn regularly to keep it healthy. But did you know overwatering can affect your grass too? We're in Queensland and know better than anyone that summer also calls for torrential tropical rains. Before watering, be sure to check the weather forecast and plan accordingly. You don't want all that hard work going to waste now, do you?

Additionally, check your lawn's soil. If it feels too dry, give it a big drink.

And remember: one big drink is more effective than several little ones, so make sure you give your lawn enough water from the get-go.

In order to prevent evaporation, we recommend watering your lawn in the morning so the soil has time to absorb it. Avoid watering at night, as a damp lawn can become a breeding ground for pests and weeds.
