Any recommendations on how to stop or at least slow the march of wild parsnip -- a plant that leaves blisters when sunlight falls on skin that touched the plant. We are reluctant to use herbicides at our new home. Perhaps wild parsnip grows best in some sort of soil, and we could control by changing to more alkaline -- or vice versa?

Nope, soil change won't work.

Dear Equilibrium, thanks for pointing me to the thread already started. I'll pursue the recommendation lower in the thread on how to attack these dastardly critters. Two landscaper types, who knew of the dangers, have fallen in the line of duty while trying to help me. I am in the southeast corner of Iowa, and very few people seem to know of this plant and its dangers.
