Crabgrass vs. Bermuda Grass: How to Spot the Differences

While crabgrass and Bermuda grass share similarities in their rapid growth and ability to overtake a landscape, their ultimate impact on your lawn couldn’t be more different. Bermuda grass forms a dense, vibrant, and desirable turf, although it spreads rapidly and can encroach if not maintained. Crabgrass also spreads rapidly but is universally shunned as a weed. So, what distinguishes these two grasses? Here’s how to tell the difference between crabgrass vs. Bermuda grass.

What Is Crabgrass?

Crabgrass is a type of grass that is considered a weed. Its flat, broad leaves grow in clusters that protrude out from the center, much like the legs of its namesake crustacean. Crabgrass thrives in compacted soil and areas with poor lawn care practices. If you need help removing crabgrass from your yard to make room for more appealing grass varieties, such as Bermuda grass, consider hiring a local lawn care professional to tackle the task.

Best for:

• Lawns in need of quick coverage

• Areas where grass struggles to establish

Pros of Crabgrass

There aren’t many pros to crabgrass—most people dislike it and will try to get rid of it. Still, it can bring a touch of green to otherwise barren land, as it can grow despite soil that is compacted or devoid of nutrients. Crabgrass also grows fast, which may be a benefit for those seeking rapid coverage.

Cons of Crabgrass

While it’s not classified as a type of noxious weed, Crabgrass is considered a weed. In most cases, it grows where it isn’t wanted, and rapidly so. Plus, it grows aggressively once established, often crowding desirable turf grass and out-competing it for nutrients from the soil. 

What Is Bermuda Grass?

So, what is Bermuda grass? Bermuda grass is a popular warm-season turf grass prized for its fine texture, dense growth, and hardiness against foot traffic. It’s a common choice for Southern and coastal regions that have hot summers and mild winters.

Best for:

• Warm climates with little to no frost periods

• High-traffic lawns

• Golf courses

• Soccer fields

Pros of Bermuda Grass

Besides its vibrant color and thick, carpeting growth, a key benefit of Bermuda grass is its ability to withstand heavy foot traffic. When trampled, it’s quick to bounce back, making it ideal for high-traffic lawns and sports fields. Additionally, it has a very quick growth rate, so it can quickly fill in bare and patchy areas.

Bermuda grass is also renowned for its exceptional drought tolerance, thanks to its deep and extensive root system. This root system enables the grass to access moisture from deeper layers within the soil, allowing it to withstand longer periods of drought than other warm-season grasses.

Cons of Bermuda Grass

Bermuda grass has very low cold tolerance and can’t grow in shade, so it’s limited to thriving only in warm, sunny conditions. Its fast-growing nature can be a disadvantage since its spread is difficult to control. It commonly encroaches on gardens, raised garden beds, and other unwanted areas. Plus, its deep root system can get tangled in landscape fabrics and be extremely difficult to remove.

Another potential downside of Bermuda grass is its tendency to go dormant and turn brown during cooler months. While this dormancy is a natural response to environmental stressors that helps the grass conserve energy, it can detract from its visual appeal. Since Bermuda grass has exceptionally low cold tolerance, it tends to go dormant earlier than other grass types in cooler climates.

Crabgrass vs. Bermuda Grass

There’s not much competition here: Bermuda grass is considered one of the desirable types of grass for lawns, while crabgrass is known as a weed. Here’s how to differentiate between crabgrass vs. Bermuda grass.

Appearance: Bermuda Grass

Bermuda grass has thinner, finer leaves that are medium to dark green. Under warm, sunny conditions and with proper care, it forms a dense, lush turf carpet. Crabgrass has a light to yellowish-green color and grows in clumps rather than forming dense turf.

Texture: Bermuda Grass

Bermuda grass has thinner, finer blades that are softer than crabgrass. The spindly leaves of crabgrass are coarse and rough to the touch. 

Growth Rate: Tie

Both Bermuda grass and crabgrass have exceptionally fast growth rates. In most cases, this is a pro for Bermuda grass and a major con of crabgrass. However, one of the benefits of regular lawn aeration and proper upkeep is it can slow the growth of crabgrass and prevent it from taking over a healthy lawn.

Root System: Bermuda Grass

One major difference between crabgrass vs. Bermuda grass is their root systems. Bermuda grass is known for its deep root system. Contrastingly, crabgrass has a very shallow root system. 

Adaptability: Crabgrass

Unlike most grasses, crabgrass can thrive in compacted soil and areas with poor lawn care. Under these conditions, it can overtake most other types of grass. Bermuda grass has limited adaptability, as it can only thrive in healthy, aerated soil, full sun, and warm weather.

Control: Tie

Figuring out how to remove grass for both grasses can prove extremely challenging, as Bermuda grass has a deep root system and crabgrass has an extremely aggressive growth rate. In either case, hiring a lawn care service may be necessary to aid with removal. Get in touch with a local lawn care service to learn more about your options.
