WARNING .........................
To prevent seeding, plants can be mowed or cut back with a weed-eater before going to flower. Protect yourself with a dust mask to avoid inhaling toxins while mowing. Adding a layer of mulch to the area after it has been cleared or replanting with desirable vegetation will reduce germination of poison hemlock seeds present in the soil. Monitor mowed areas as plants often grow back after being mowed.
