Can I spray Roundup on cattails?
Glyphosate is a systemic herbicide which means it will kill the whole plant even if only part of the plant is sprayed. Dilute 2 2/3 ounces of 53.8 percent glyphosate in 1 gallon of water, put it in a garden sprayer and spray it evenly on the cattails.
How do you get rid of cattails naturally?
