Goosegrass

Eleusine indica

Quick Definition

Goosegrass is a summer annual grassy weed that forms flat, dark green rosettes with a distinctive white or silver center (zipper pattern). It thrives in compacted soil and germinates 2 to 3 weeks later than crabgrass.

How to Identify Goosegrass

Goosegrass (Eleusine indica), also called silver crabgrass or wiregrass, grows in a flat rosette pressed tight against the ground. The defining feature is the white or silvery-white center where all the stems originate, creating what lawn care professionals call the “zipper pattern” or “white center.”

The blades are dark green (noticeably darker than crabgrass), flat, and folded along the midrib. Seed heads have 2 to 6 finger-like branches that are thicker and more compact than crabgrass seed heads. The entire plant lies flatter to the ground than crabgrass and has a tougher, more wiry texture.

Where and Why It Grows

Goosegrass is the weed that tells you your soil is compacted. It thrives in areas with heavy foot traffic, along walkways and driveways, in sports turf, and anywhere the soil has been compressed. It tolerates compaction better than almost any other plant, including your lawn grass.

It germinates 2 to 3 weeks later than crabgrass, typically when soil temperatures reach 60 to 65 degrees. This means pre-emergent applied for crabgrass timing may not last long enough to prevent goosegrass. A split application or a product with longer residual is needed for areas with both weeds.

Commonly Confused With

PlantKey Difference
Crabgrass Lighter green, star-shaped spreading growth (not flat rosette), no white center. Germinates earlier at 55 degrees. Blades are wider and less wiry.
Annual Bluegrass (Poa annua) Light green, fine-textured, produces white seed heads even at mowing height. Germinates in fall, not summer. Prefers cool, moist conditions rather than compacted heat.

Frequently Asked Questions

Why does goosegrass grow in my driveway cracks?

Goosegrass thrives in compacted soil and hard surfaces. Driveway edges and cracks provide the compressed, warm conditions it prefers. It's one of the few plants that actually grows better in compacted soil than loose, healthy soil.

Does crabgrass preventer stop goosegrass?

Sometimes, but not always. Goosegrass germinates 2 to 3 weeks after crabgrass. If your pre-emergent barrier has started to break down by then, goosegrass comes through. A split application (half rate in early spring, half 6 weeks later) provides longer coverage for both weeds.

How do I get rid of goosegrass?

Pull individual plants by hand after rain (they come up relatively easily when young). For larger infestations, post-emergent herbicides containing quinclorac or fenoxaprop provide selective control. Aerate compacted areas in fall to reduce favorable conditions for next year.

Will aeration prevent goosegrass?

Core aeration reduces soil compaction, which is the primary condition goosegrass exploits. Aeration alone won't eliminate existing plants, but combined with overseeding and pre-emergent, it significantly reduces goosegrass pressure over time.
