Northern Ohio | Jimson weed grows where there is excess organic matter that is not breaking down well because the soil is out of balance. We see it around old feedlots, old grain spills, old manure piles. Very difficult to deal with until soil balances, which should happen with time, but may take a long time.
You will have to be very aggressive with a flame cultivator to control it. Once it gets about 6” tall the stem starts to get too thick for the heat to penetrate. At that stage it will still wilt after the flame cultivator and you can bury it.
We have a patch that is so thick we have not been able to farm for a couple years, old lot for over wintering cows. | |
