The retired engineer fine-tuned his approach and became more methodical. He has an aerial map marked with about 80 garlic mustard patches on his property. He sprays the patches with an herbicide each spring, re-checks each site several times, pulls plants if he finds any that are flowering, and uses a spreadsheet to keep track of it all.

Now that he’s been at it for five years, Peterson said he’s beginning to see success. Wildflowers and tree saplings are returning, and garlic mustard patches are spotty. “I’ve got the upper hand on it now, and I’m going to kill every one of them,” he said.
