Question: How can I get rid of nutgrass?
Answer: It's actually not a grass, but a sedge, so conventional grass killers will not impact it. You can identify nutsedge by its triangular stems. If you roll them between your thumb and index fingers, if the weed is a true grass, its stems will be round. If you can feel a triangular shape, you have a sedge. Use a herbicide that is specifically for the control of nutsedge such as Image or Sedgehammer. Read and follow label directions carefully. Their chemistries vary, as will directions for their use. Late spring, summer and very early fall will be the prime times for control.
