[Arid_gardener] Nut Grass

[Dick Gross]

Cathy, thanks for that wisdom. Most of us have come to believe that 
eradicating Nutsedge is a job for Superman using TNT and the power of 
prayer. When we did away with the grass on the East side of the Extension 
building, we knew the Bermuda would be persistant but some one forgot to 
tell us the Nut Grass would be difficult. It wasn't but we had to work at 
eliminating the Bermuda and wire-grass for several years by poping out an 
ocassional blade of grass and its stolen with a trowel. We screened the top 
4 to 5 inches to get rid of 90% of the live stolens or junctions. We used no 
chemicals because a few of our members were dead set against it. After six 
years, there is no grass in that area, not even the medicinal variety.

Today, I would have no qualms about using either Manage, Image or Monument.
