If you've ever searched “how to make my grass green” or “how to get greener grass”, you're not alone. A healthy, green lawn is the dream of many homeowners — and with the right lawn care strategy, it's completely achievable.
Whether you’re dealing with patchy grass, dull colour, or bare spots, this guide will walk you through the essential steps to transform your lawn into a vibrant, green oasis. From mowing and watering to fertilising and weed control, here’s how to get your grass greener and healthier, all year round.
- 1. Mow Correctly for Healthier, Greener Grass
Proper mowing is one of the most important ways to keep your lawn looking lush and green. Cutting your grass too short can weaken it, while the right height encourages growth and helps shade the soil — reducing weeds and moisture loss.
Ideal mowing height by grass type:
- Cool-season 5–7.5 cm
- Warm-season 2.5–5 cm
Top mowing tips:
- Follow the 1/3 rule: Never cut more than a third of the blade at once.
- Mow weekly during peak growing season.
- Keep blades sharp: Dull blades tear grass, causing browning and disease risk.
- Maintain your mower: Clean, oil, and replace filters regularly
2. Watering: How to Hydrate Your Lawn for a Greener Look
A common question we hear is, “How much should I water my lawn to make it green?” The answer depends on your grass type, soil, and weather — but generally, lawns need about 1 inch (2.5 cm) of water per week.
Watering best practices:
- Water early morning (before 10 am) to reduce evaporation.
- Water deeply, not daily: One or two sessions per week is better than light, frequent watering.
- Avoid overwatering: It can lead to shallow roots, fungus, and weak grass.
- Use a soil moisture gauge to avoid guesswork.
- Collect and use rainwater where possible — it’s natural and nutrient-rich.
3. Feed Your Lawn with the Right Fertiliser
Fertilising provides the essential nutrients your lawn needs to grow thick and vibrant. If your lawn looks tired or pale, it’s likely due to a lack of nitrogen, the nutrient responsible for lush green colour.
Fertiliser tips for greener grass:
- Use a nitrogen-rich fertiliser for colour and growth.
- Test your soil to understand its nutrient needs.
- Apply using a spreader for even coverage.
- Water lightly after application to help nutrients absorb.
- Avoid applying before heavy rain to prevent washout.

4. Control Weeds & Moss to Maintain That Green Lawn
Weeds and moss can ruin even the greenest of lawns. If you're wondering how to make your grass green and weed-free, this step is essential.
Weed control tips:
- Hand-pull or use a hoe for small infestations.
- Use selective weed killers for more widespread issues.
- Keep your lawn thick — healthy grass naturally prevents weed growth.
Moss control tips:
- Reduce shade and improve airflow by pruning overhanging trees.
- Aerate compacted soil to improve drainage.
- Apply a moss control treatment (often included in professional services).
- Keep your soil pH balanced and fertilised to help grass outcompete moss.
Bonus Tips for a Healthier Lawn:
- Aerate your lawn annually to improve soil health and nutrient uptake.
- Overseed patchy or thin areas with fresh grass seed.
- Scarify in autumn or spring to remove thatch and moss buildup.
- Hire a lawn care expert if you're unsure where to start — professional treatments can save time and money in the long run.
