Q: I write for clarification about eradicating bindweed. Your response was to use half-strength Round-Up in a floral pick, then “Cut the weed stem and place the ends into the pick.”

I have English Ivy growing up Douglas firs here in Seattle. If I cut the vine at some point along its growth upward, do I put the end connected still to the roots into the floral pick as well as the upward end of the vine clinging to the tree?

Will this work for English Ivy which is not bindweed but equally pernicious? Is there a better technique for Ivy on trees?

Many of these invasive vines will root along the entire length of their stems, making them even more obnoxious. If you place both cut ends into floral picks containing Round Up, the entire vine will die. This should also work for English Ivy.
