Living on the Sunshine Coast means we enjoy sunshine, coastal breezes, and lush greenery. But to keep your lawn thick, green, and healthy here, fertilization isn’t optional, it’s essential.
Our warm climate helps grass grow fast, yet sandy soils and seasonal rains often wash nutrients away. That means Sunshine Coast lawns need regular feeding to stay healthy and resist weeds, pests, and stress.
Whether you’re in Beerwah, Caloundra, Noosa, or anywhere in between, this guide covers everything you need to know about fertilizing your lawn the right way.
Why Fertilization Matters on the Sunshine Coast
Sunshine Coast lawns face:
-
Hot summers
-
Seasonal heavy rain
-
Humidity
-
Sandy, nutrient-poor soil in many areas
Because of this, fertilization helps provide:
-
Greener, thicker grass
-
Stronger roots
-
Better drought and heat tolerance
-
Natural weed resistance
-
Recovery from foot traffic and coastal exposure
Without feeding, lawns can become patchy, weak, and pale — especially near coastal areas where salt and sand affect soil quality.
Best Time to Fertilize Your Lawn
A good fertilizing schedule includes:
-
Spring (Sept–Oct): Kick-start new growth
-
Summer (Dec–Jan): Slow-release fertilizer to protect during heat
-
Autumn (March–April): Strengthen roots and prepare for cooler months
Tip: Avoid fertilizing during extreme heat unless you’re able to water right after.
How Often Should You Fertilize?
Most lawns here thrive with 3–4 treatments a year.
Buffalo and Zoysia typically need fewer applications, while Couch lawns often benefit from slightly more due to faster growth.
If your grass gets heavy use pets, kids playing, high foot traffic, an extra application may help keep it looking lush.

How to Fertilize Your Lawn Properly
-
Mow your lawn a few days before fertilizing
-
Remove leaves and debris
-
Spread fertilizer evenly, use a spreader for best coverage
-
Water lightly afterward (unless using liquid feed, which already includes water)
-
Sweep granules off paths and driveways to avoid stains
Consistent watering is key. Fertilizer needs moisture to activate and move into the soil.
Don’t Forget Pest & Lawn Disease Protection
After fertilizing, lawns grow fast and pests notice. Keep an eye out for:
-
Lawn grubs
-
Armyworm
-
Dollar spot fungus
-
Brown patch
If you see discolored patches, chewed grass, or sudden yellowing, treat the issue quickly to avoid long-term lawn damage.

Rich green colour
