Eliminating Oxeye Daisy from hayfield #873323
Asked June 16, 2024, 2:38 PM EDT
What are the options for eliminating oxeye daisy from a hayfield? We have been pulling this invasive weed for a number of years now. I understand that it propagates from seed and roots. We would prefer not to use herbicides.
Is horticultural vinegar an option? I know that vinegar does not kill the roots, however, if we keep hitting it with this as well as pulling the roots and flowerheads will it help?
What other options are available? Can you point us to good scientific articles on this? Does extension have articles? (It's too hard trying to wade through your pdfs)
Thank you..

Hello and thanks for your question. This guide on managing Oxeye Daisy from USDA may be helfpul: https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/fseprd563036.pdf

vinegar along is unlikely to remove the plants. Since they spread easily by rhizomes, applying vinegar to the tops isn't likely to do anything in the long run- they will come back from the roots.
The key here is to remember that these plants spread easily via both roots (rhizomes) and seed. Removing the plants before they flower, or mowing the flowers before they go to seed, is helpful- this plant throws a lot of seed. Second, and where the links don't seem to specify, is that when you till or hoe to remove the plants, it's important to get as much of the roots as possible. The plants can come back from root sections.
I hope you find this helpful, Nicole
