Hi there, I live along the Huron River in Dexter Michigan and the grasses and wildflowers near the river and being overrun by Dodder. I'm concerned that it will soon overtake EVERYTHING. I have been trying to cut the grasses/weeds before the dodder seeds, but that also means cutting milkweed and joepye weed, etc. I'm trying to dry the weeds so the Dodder seeds/flowers die, but now I'm not sure what to do with all the dead weeds that have the Dodder twining and flowering about them. Please HELP!
If burning vegetation is allowed in your area, it is one option to dispose of the cut plants. If that is not an option, then bag the plant materials and seal the bags and discard. Dried out dodder that has no seed will not generate new plants. You may have to kill and discard herbaceous plants infected with dodder.
Here are some articles that describe dodder control. It survives on particular host plants. Next year use one of the suggested pre-emergent chemicals so that dodder seeds won’t establish in your landscape beds. You will need to continue using pre-emergents in your landscape depending on how many years it has been producing seed in that location.
Dodder is an annual here. I hope this is of some help to you. Thanks for using our service.
