Bermuda grass also looks more lovely but also comes at a higher price tag than Crabgrass.

Crabgrass is essentially a weed while Bermuda is a turf grass and one of the best ones at that. Both being warm season grasses don’t go well against low temperatures. You need full sunlight for optimal growth. Crabgrass doesn’t grow in shady areas. Both Bermuda and crabgrass have high traffic tolerance as well.

Comparing Crab Grass vs Bermuda

Comparing Crab Grass vs Bermuda

By now, it is clear that these are two very different grass types that are suited to entirely different purposes. We have compared the two in different categories so that you can get a better understanding of them.

Appearance (Smooth Crab grass vs Bermuda grass)

Appearance-wise, crab grass has very deep roots. With its big stem, it is not able to tolerate shade. The leaves are flat with pointy ends.

In contrast to the crab grass, Bermuda is totally different. It also comes with flat blades but with hairs on them. It forms a comfortable carpet on the ground.

Weeds, growth, and sod formation

Both of these grasses are very invasive and don’t any other plants to grow. So, weeds aren’t a problem for them. Both grow extremely fast which makes maintenance a hassle.

Crab grass grows in the form of clusters while Bermuda grass spreads through the stolons and rhizomes. Both of them have strong roots to withstand high traffic. You can get rid of the weeds using a pre emergent herbicide.

Best Uses

Bermuda grass with its complex roots and strong durability is great for busy areas. Also has a high tolerance to drought. Using Bermuda grass provides the feeling of flower beds.

Crab grass is a weed that does marvelously in high-traffic areas. While not having the flower beds feel but still is quite relevant in areas where there is a lot of heat and traffic. However, it is not suitable as lawn grass and thus is a highly undesirable weed.

Soil Types and pH Needs

Crab grass can be adapted to a lot of different soils but it generally prefers soil that is well-drained. It is very pH tolerant and can easily grow in varying pH levels from 5.5-7.5

Bermuda also requires well-drained fertile soils for the best growth. If you want Bermuda to grow faster then a pH between 6-7 is ideal. Sandy soil is great for the fast growth of Bermuda.

Water Needs

If you want to quickly sprout crabgrass seeds then you have to water them daily. However, as this is an invasive weed, you shouldn’t overwater it. Watering it two times per week is optimal.

Common Bermuda grass is also very invasive. When it comes to watering it, you only need about 1.5″/week. This is the ideal amount of watering required to maintain a pleasant-looking green lawn.

Fertilizer requirements

You need about 1 to 2 pounds of nitrogen in order to ensure optimal growth of crab grass seed heads.

When choosing the best fertilizer for Bermuda seed heads, make sure to choose one with no phosphorus, a high amount of nitrogen, and some potassium.

Sun, Shade, and Temperature Requirements (Warm Season Grass)

These grasses are pretty similar in one aspect. These are warm-season grasses. Crab grass likes direct sunlight and will not grow well in a cold area.

Bermuda grass tolerates high heat easily and prefers direct sunlight. It doesn’t tolerate shade and gets easily damaged if not enough sunlight is present. Due to the lack of sunlight, brown spots will start to appear in bermuda grass and it will get thinner over time.


These lawn grasses are highly durable. Crab grass with its rough texture and deep roots is pretty durable. It does remarkably well in high-traffic areas.

Common Bermuda grass due to its enhanced durability is used in a lot of traffic-intensive areas. It is a highly desirable lawn grass and Bermuda grass tolerates traffic like a champ.

Common Pests and Diseases

It is clear by now that Bermuda grass is a home lawn grass while crabgrass is a weed. Being a weed itself, crab grass itself is a problem to other lawn grasses due to its invasive nature.

Insects pose a threat to Bermuda grass but not as big as digging animals. This is due to the slower recovery time of this turf grass.

Mowing Needs

In order to control the crab grass, you need to mow it. The best height to mow crab grass is about 3 1/2″. Crabgrass thrives in this way without overwhelming other plants.

You need to mow bermuda about 2″. Its aggressive growth habits in the summer make it necessary to do a lot of mowing.

Cost of Maintenance

The cost of maintenance is pretty different for both types of grasses. On one hand crab grass requires a lot more resources to grow but Bermuda grass maintenance is also tough. This is due to its frequent mowing requirement. If you are regularly taking care and maintaining then the cost wouldn’t reach high.

Crab Grass vs Bermuda: Which Option is Right for You?

It entirely depends upon your use case. People use grasses in their homes, fields, etc. So, in order to make it easier for you, we have made different sections and will provide you with a straight and simple answer.

Choosing the Best Option for Climate

As both crab grass and Bermuda are warm seasoned, they prefer areas with high temperatures. So, it’s safe to say that they are warm season grass & prefer the hot summer months. They are also highly drought tolerant and don’t prefer shade.

Growing zones

Crab grass essentially spreads rapidly, grows everywhere and more so in home lawns. Bermuda grows best in the USDA zones of 7 to 10.

Summary: Both are more or less the same. But as Bermuda can be used a lawn grass, it comes out on top.

Choosing the Best Option Based on Maintenance

The maintenance needs for both types of grass are very similar. Crab grass is a high resource-demanding weed whereas you have to frequently mow Bermuda. Bermuda is also more expensive.

Summary: We think that crabgrass is better as it grows everywhere and requires less mowing

Choosing the Best Option Based on Susceptibility to Pests and Disease

In terms of pests and disease, both types of grass are quite similar. But the nail in the coffin for Bermuda is its slow recovery time

Summary: Due to its higher durability, Crab grass is the better choice.
