How to Grow and Maintain Kikuyu Grass
When it comes to creating a lush, durable, and low-maintenance lawn, Kikuyu grass is a top choice for many New Zealand homeowners. Known for its rapid growth and ability to withstand heavy foot traffic, Kikuyu grass is perfect for families, pets, and outdoor enthusiasts.
Whether you’re starting a new lawn or looking to improve your existing one, this Jim’s Mowing NZ guide will walk you through everything you need to know about growing and maintaining Kikuyu grass.
What is Kikuyu Grass?
Kikuyu grass (Pennisetum clandestinum) is a warm-season grass native to East Africa. It was introduced to New Zealand and Australia in the early 20th century and has since become a popular choice for lawns, sports fields, and public spaces. This grass is known for its:
- Rapid Growth – Kikuyu grass spreads quickly through both above-ground runners (stolons) and below-ground stems (rhizomes), making it ideal for filling in bare patches.
- Durability – It can withstand heavy foot traffic, making it perfect for active households and high-use areas.
- Drought Tolerance – Once established, Kikuyu grass has excellent drought resistance, thanks to its deep root system.
- Vibrant Green Colour – When well-maintained, Kikuyu grass boasts a lush, green appearance that enhances the beauty of any outdoor space.
What Makes it a Great Grass for Your Lawn
Kikuyu grass offers several benefits that make it a standout choice for New Zealand lawns:
- Hard-Wearing
Its ability to recover quickly from damage makes it ideal for families with children and pets.
- Low Maintenance
Compared to other grass types, Kikuyu requires less watering and fertilising once established.
- Weed Suppression
Its dense growth habit helps prevent weeds from taking over your lawn.
- Cost-Effective
Kikuyu grass is relatively inexpensive to establish and maintain, making it a budget-friendly option.
- Adaptability
It thrives in a variety of soil types and can tolerate both sun and partial shade.
How to Plant a Kikuyu Lawn
Planting a Kikuyu lawn is straightforward, but it requires careful preparation to ensure success. Follow these steps to create a thriving Kikuyu lawn:
Step 1: Choose the Right Time
The best time to plant Kikuyu grass is during the warmer months (spring or early summer) when the soil temperature is consistently above 15°C. This allows the grass to establish quickly.
Step 2: Prepare the Soil
- Clear the Area – Remove any existing grass, weeds, rocks, or debris from the area.
- Loosen the Soil – Use a rotary hoe or garden fork to loosen the soil to a depth of at least 10-15 cm. This promotes root growth and drainage.
- Level the Ground – Rake the soil to create a smooth, even surface. Fill in any low spots to prevent water pooling.
Step 3: Sow the Seeds or Lay Turf
- Seeding – Spread Kikuyu grass seeds evenly across the prepared soil. Use a seed spreader for even coverage, and lightly rake the seeds into the soil.
- Turfing – If using Kikuyu turf, lay the rolls tightly together, staggering the joints like bricks. Water thoroughly after laying.
Step 4: Water Regularly
- Keep the soil consistently moist (but not waterlogged) until the grass establishes. This usually takes 2-3 weeks for seeds and 1-2 weeks for turf.
- Water deeply once or twice a week, depending on weather conditions.
Step 5: Fertilise
- Apply a slow-release fertiliser after the grass has established to encourage healthy growth and root development.
Maintaining a Kikuyu Lawn
Once your Kikuyu lawn is established, regular maintenance will keep it looking lush and healthy. Here’s how to care for your Kikuyu grass:
- Mowing
Mow your Kikuyu lawn regularly to keep it at a height of 2-4 cm. Avoid cutting it too short, as this can stress the grass and encourage weed growth.
Use a sharp mower blade to ensure clean cuts and prevent damage to the grass.
- Watering
While Kikuyu grass is drought-tolerant, it still needs regular watering during dry spells. Water deeply once a week to encourage deep root growth.
Avoid overwatering, as this can lead to fungal diseases.
- Fertilising
Apply a balanced fertiliser (e.g., NPK 10:10:10) every 6-8 weeks during the growing season (spring and summer).
Avoid over-fertilising, as this can lead to excessive growth and thatch buildup.
- Weed Control
Hand-pull weeds as soon as they appear, or use a selective herbicide designed for Kikuyu grass.
Maintain a dense lawn to prevent weeds from taking hold.
- Aeration
Aerate your lawn once or twice a year to improve soil drainage and reduce compaction. This allows air, water, and nutrients to reach the roots more effectively.
- Dethatching
- Remove excess thatch (a layer of dead grass and roots) using a dethatching rake or machine. This prevents water and nutrient blockage.
