Goosegrass. The summer annual weed grows in clumps, thriving in thin open turf and turf that’s subject to intense traffic or use. Properly identifying and understanding it is key to controlling the troublesome grassy weed.
How to spot goosegrass
- Grows in a clump with the base of the leaves being silver to white
- Leaves are folded and may be smooth with few hairs
- Features a strong, extensive root system
- Readily invades hard, compacted soils
Goosegrass is also a prolific seed producer. In most cases, one plant has three to seven fingerlike racemes on a stem. A mature plant can grow 20 stems and have as many as 50,000 seeds. Once goosegrass becomes established, annual reinfestations are likely to occur.
