Bermuda Grass Vs Crabgrass – Can You Spot the Contrast?

bermuda grass vs crab grass

Which is Best for Your Lawn: Bermuda Grass or Crabgrass?

Bermuda grass Vs crabgrass are common grasses found in lawns. Bermuda grass is a warm-season grass known for its tolerance to heat, drought, and heavy foot traffic. It forms a dense, fine-textured turf and spreads through stolons and rhizomes.

In contrast, crabgrass is an annual weed with a lighter green color and coarser texture than Bermuda grass. It thrives in warm weather and spreads rapidly through seed germination. Unlike Bermuda grass, crabgrass grows in clumps and does not have stolons or rhizomes.

Another difference is their appearance. Bermuda grass has narrow, pointed leaves that create a uniform turf with a low mowing height. Crabgrass leaves are wider and have a rough texture, growing in patches that stand out from the surrounding turf.

Furthermore, their life cycles vary. Bermuda grass is a perennial grass that survives year-round, going dormant in colder months and regrowing from its extensive root system when the weather warms up. Crabgrass, on the other hand, is an annual grass that completes its life cycle within a single year. It germinates in spring, grows vigorously during summer, produces seeds, and dies off in fall.

Understanding these distinctions between Bermuda grass and crabgrass is essential for effective lawn management and controlling the spread of crabgrass in Bermuda grass lawns.
