How to stop grass runners in buffalo lawns

Buffalo lawns are renowned for their hardiness and lush appearance, but there's one challenge that can catch even the most diligent lawn owners off guard—buffalo grass runners. These sneaky, fast-spreading growths can quickly turn your neat lawn into an untamed jungle, creeping into garden beds and over pathways.

But don’t worry! You don’t have to let these runners take control. In this blog, we’ll walk you through the causes behind buffalo grass runners, how to stop them in their tracks, and the best methods for keeping your lawn looking tidy and well-maintained.

What are buffalo grass runners?

Buffalo grass runners are horizontal growths that spread out from the main grass plant. Unlike the vertical blades of grass you usually see, these runners are long, creeping stems that seek new areas to establish roots and grow new grass. This ensures your Sir Walter buffalo grass spreads, whether you want it to or not. 

Why do buffalo grass runners form?

• Spreading growth habit: Buffalo grass is naturally aggressive and spreads via runners (also known as stolons).
• Filling bare spots: If there are patches of bare soil, the grass sends out runners to fill those areas.
• Lack of maintenance: Irregular mowing and insufficient edging encourage runners to spread uncontrollably across the entire lawn.

How do runners contribute to the growth of buffalo grass?

Buffalo grass runners play a vital role in the plant’s natural ability to spread and cover large areas. These horizontal stems, or stolons, extend out from the main grass plant, allowing new roots to develop at multiple points along their length. As they establish themselves in the soil, the runners help fill in bare spots and create a denser, more resilient lawn. While this spreading growth habit can help maintain a lush lawn, it also makes buffalo grass highly invasive if not properly managed.

How deep do buffalo grass roots grow?

Buffalo grass roots typically grow between 15 to 30 cm deep, depending on soil conditions and care. This relatively deep root system allows the grass to access moisture and nutrients from deeper in the soil, making it more drought-resistant compared to other grass varieties.

How to stop buffalo grass runners from spreading

If left unchecked, buffalo grass runners can spread beyond the lawn area and cause problems in other parts of the garden. Here’s how you can effectively stop them:

1. Regular mowing

One of the most effective ways to manage buffalo grass runners is by mowing your lawn regularly. Mowing helps to prevent the runners from growing too long and encourages vertical growth.

• Mow your buffalo grass every 7-10 days during the growing season.
• Keep the mowing height at 4-6 cm to maintain healthy growth.
• Be cautious not to mow too low, as this can stress the grass and lead to more runner formation.

2. Edging your lawn 

Creating a physical barrier between your lawn and garden beds is crucial to stopping the spread of buffalo grass runners.

• Install garden edging: Use materials like bricks, stones, or plastic borders to create a defined edge.
• Trench edging: Dig a shallow trench around the edge of your lawn to act as a buffer zone.
• Regular trimming: Use a lawn trimmer to cut back any runners that creep over the edging.

3. Fertilise carefully 

Fertilising your lawn is essential for healthy growth, but over-fertilising can stimulate excessive runner growth. Use a balanced fertiliser designed for buffalo grass and follow the recommended application rates.

• Apply fertiliser every 8-10 weeks during the growing season.
• Ensure you choose a slow-release nitrogen fertiliser to avoid a sudden burst of growth.

4. Watering correctly 

Overwatering can lead to excessive growth and more runners, while under-watering can weaken the lawn and encourage runners to spread in search of moisture.

• Water deeply but infrequently to encourage deep root growth.
• Aim to water 1-2 times a week, depending on the weather.

How to remove buffalo grass runners

If buffalo grass runners have already spread into unwanted areas, there are a few ways to remove them and prevent further spread.

1. Hand removal 

The most straightforward method is to manually pull up the runners. It’s essential to remove the entire runner, including its roots, to prevent regrowth.

• Step 1: Grab the runner close to the base.
• Step 2: Gently pull it out, ensuring you remove the entire length and roots.
• Step 3: Dispose of the runners in green waste or compost.

2. Use a lawn scarifier

A scarifier is a specialised tool designed to remove thatch (dead grass) and buffalo grass runners from your lawn. This tool digs slightly into the soil and pulls up the runners, helping to reduce the spread.

• Use a scarifier once or twice a year to prevent the build-up of runners.
• Scarifying also helps to aerate the soil and improve lawn health.

3. Herbicides for severe cases

If runners have taken over, and manual removal isn’t effective, you may need to use a herbicide designed for buffalo lawns. Be careful when selecting herbicides, as not all products are suitable for buffalo grass.

• Selective herbicides: Choose a product that targets broadleaf weeds and grass runners without harming your buffalo lawn.
• Follow label instructions: Always apply herbicides according to the manufacturer's guidelines to avoid damaging your warm season grasses.

Preventing buffalo grass runners from spreading to unwanted areas: best practices 

By following a regular maintenance routine, you can prevent the excessive spread of buffalo grass runners and maintain a neat, healthy lawn.

Here are some tips to keep in mind:

• Regular mowing: Keep your grass blades at the recommended height to discourage runner formation.
• Edging and trimming: Use barriers and regularly trim the edges to stop runners from creeping into any garden bed.
• Proper watering and fertilising: Avoid over-watering and over-fertilising, which can lead to excessive growth.
• Monitor lawn health: Identify and fix bare patches early to prevent runners from spreading.
