WEED ID · PERENNIAL SEDGE
Green kyllinga
Also called Kyllinga, shortleaf spikesedge
A sedge, not a grass. It forms low patches that look different from your lawn and spreads from underground stems.

How to spot it
- Fine, narrow leaves in patches that spread outward like turf
- Triangular flower stalks, 2 to 8 inches tall
- Small, round green flower head about 3/8 inch across
- Three leaves spread out right below each flower head
- Turf can look bumpy or uneven where patches spread
Why it shows up
Green kyllinga grows from rhizomes and from seed. It does best in wet, sunny spots and low areas. Mowing and foot traffic can spread pieces and seed.
How we treat it
Kyllinga is a tough perennial, so one visit is rarely enough. We spot treat with a product labeled for sedges and for your grass type. We come back for repeat visits as new growth shows up. We also fertilize to keep your turf thick.
What you can do
- Check for leaks, drainage problems, and overwatering. Wet soil feeds kyllinga.
- Clean your mower before you move from a weedy spot to clean turf.
- Call early, when patches are still small.
