WEED ID · PERENNIAL GRASS
Dallisgrass
Also called Dallis grass
A coarse perennial grass that grows in clumps. It stands out from the lawn, and it is very hard to control because of its deep roots.
How to spot it
- Coarse, wide clumps that grow faster than the lawn
- Clumps get bigger each year
- Tall seed stalks with 2 to 8 finger-like branches
- Seed branches have rows of small spikelets
- Looks different from your lawn grass, often lighter or darker
Why it shows up
Dallisgrass grows from a tough root system with short rhizomes, so the clump gets bigger each year. It also drops seed. It does well in lawns that are thin or mowed short, and it spreads in wet spots.
How we treat it
Dallisgrass is a tough perennial, so it takes repeat visits. We spot treat the clumps with a product labeled for your grass type, timed for when the plant is actively growing. We also fertilize to thicken the turf. Large clumps may need more than one season.
What you can do
- Do not mow seed stalks and spread the seed. Bag them if you can.
- Digging can work for very small clumps. Get the whole root.
- Call early. Small clumps are easier to deal with than big ones.
