Q: I have been manually trying to dig this plant up in my yard and it keeps coming back. Does it respond to salt/vinegar treatment or burning? It seems to put out a lot of bulbs and tubers and is in several parts of my yard. I don't like using chemicals in my yard, so that isn't an option.
With targeted research, Oregon State University Extension Service and the Oregon Agricultural Experiment Station responded by providing growers with information on better nutrient management of those crops.
