Kikuyu grass is one of the most popular lawn options in Australia due to its fast growth, durability, and ability to thrive in warm climates. If you’re looking for a lush, green lawn that can withstand high foot traffic and recover quickly from damage, Kikuyu grass is an excellent choice.

This guide will walk you through the process of planting, maintaining, and caring for a Kikuyu lawn to keep it healthy and vibrant year-round.

What is Kikuyu Grass?

Kikuyu grass (Pennisetum clandestinum) originates from East Africa and is known for its rapid growth, strong root system, and bright green colour. It’s commonly used in residential lawns, sports fields, and public parks due to its resilience and ability to spread quickly. However, its vigorous growth means it requires regular maintenance to prevent it from becoming invasive.

Benefits of Kikuyu Grass

• Fast growth and quick establishment – Ideal for covering large areas rapidly.
• Drought tolerance – Once established, Kikuyu can survive in dry conditions with minimal watering.
• Self-repairing – It recovers quickly from wear and tear, making it perfect for high-traffic areas.
• Low maintenance – While it requires regular mowing, Kikuyu is generally easy to care for.
• Adaptable – It thrives in a variety of soil types and can grow in full sun or partial shade.

How to Plant Kikuyu Grass

1. Choosing the Right Time to Plant

The best time to plant Kikuyu grass is in late spring or early summer when temperatures are warm and there is adequate sunlight to encourage germination and growth. Avoid planting in colder months as Kikuyu struggles to establish in low temperatures.

2. Preparing the Soil

Proper soil preparation is essential for a healthy lawn. Follow these steps to get your soil ready:

• Clear the area – Remove weeds, rocks, and debris.
• Loosen the soil – Use a rotary hoe or garden fork to aerate the soil to a depth of about 10-15 cm.
• Improve soil quality – Add organic compost or a sandy loam mixture to enhance drainage and nutrient content.
• Level the surface – Rake the area smooth and compact lightly to create an even surface.

3. Choosing Between Seeds, Runners, or Turf Rolls

Kikuyu grass can be established using three methods:

• Seeds – More affordable but take longer to establish.
• Runners (stolons or sprigs) – Requires patience but spreads effectively over time.
• Instant turf (sod) – The fastest way to establish a Kikuyu lawn, though more expensive.

4. Planting Kikuyu Grass

• For seeds: Spread Kikuyu seeds evenly over the prepared soil at a rate of about 10 grams per square meter. Lightly rake the soil to cover the seeds.
• For runners: Space runners about 30 cm apart and press them into the soil.
• For turf rolls: Lay turf pieces closely together in a staggered pattern, then press them down firmly.

5. Watering After Planting

After planting, water the area thoroughly and keep the soil consistently moist for the first few weeks until the grass is well-established. Watering 2-3 times daily is recommended initially.

How to Care for Kikuyu Grass

1. Mowing

Kikuyu grows rapidly and requires regular mowing to keep it looking neat and to prevent it from becoming invasive.

• First mow – Wait until the grass reaches about 5-7 cm before mowing for the first time.
• Regular mowing – Maintain a height of around 3-5 cm in residential lawns.
• Avoid scalping – Cutting too short can weaken the grass and encourage weed invasion.

2. Watering

While Kikuyu is drought-tolerant, regular watering will keep it looking lush.

• Deep watering once or twice a week is better than frequent shallow watering.
• Morning watering is ideal to reduce evaporation and prevent fungal diseases.
• Adjust based on weather conditions – Reduce watering during cooler months and increase it in hot, dry periods.

3. Fertilising

To keep Kikuyu healthy and green, fertilise regularly:

• Use a high-nitrogen fertiliser every 6-8 weeks during the growing season (spring to autumn).
• Apply organic compost occasionally to boost soil health.
• Avoid over-fertilising, which can cause excessive growth and increase mowing frequency.

4. Weed and Pest Control

Kikuyu’s dense growth helps suppress weeds, but occasional weed control may be necessary.

• Hand-pull weeds in small lawns.
• Apply selective herbicides for broadleaf weeds if needed.
• Watch for pests such as lawn grubs and armyworms, treating infestations promptly with insecticides.

5. Disease Prevention

Kikuyu is generally resistant to most lawn diseases but can suffer from fungal infections like dollar spot or brown patch in humid conditions.

• Ensure good drainage to prevent waterlogging.
• Avoid overwatering and mow regularly to improve air circulation.
• Use fungicides if needed to treat severe infections.

Common Problems and Solutions

1. Yellowing Grass

• Possible causes: Nutrient deficiency, lack of water, or compacted soil.
• Solution: Apply fertiliser, aerate the soil, and ensure proper watering.

2. Kikuyu Spreading into Garden Beds

• Possible cause: Kikuyu’s aggressive growth habits.
• Solution: Install garden edging to contain the spread and trim regularly.

3. Patchy or Thin Grass

• Possible causes: Poor soil, heavy traffic, or insufficient watering.
• Solution: Overseed with Kikuyu seeds, improve soil quality, and adjust watering habits.

Seasonal Kikuyu Lawn Care Guide

• Spring: Fertilise, mow regularly, and water deeply.
• Summer: Water more frequently, mow higher to retain moisture, and check for pests.
• Autumn: Reduce mowing frequency, apply fertiliser, and aerate the soil.
• Winter: Mow less often, reduce watering, and remove fallen leaves to prevent fungal growth.

Conclusion

Kikuyu grass is an excellent choice for those seeking a hardy, low-maintenance lawn that thrives in Australian conditions. By following proper planting techniques and maintaining a regular care routine, you can enjoy a lush, green Kikuyu lawn all year round.

Whether you’re establishing a new lawn or maintaining an existing one, consistent mowing, watering, and fertilising will ensure your Kikuyu grass remains healthy and vibrant.
