Gretchen, I will have you check out our recent factsheet on horsetail. It has a control section that might have some ideas for you.

*Note, I am having the reference to 'Roundup Weed & Grass Killer' removed because that product no longer contains glyphosate (a recent change).

If you have any questions after you check out the article, please let me know. This is a very tough plant to eliminate.
