  1. While walking past a pond, I noticed some of the tall plants, I believe they are phragmites, appear to have their tops cut off. The plants were bundled, tied, and had green coloring in the top areas. I was wondering if there was a purpose for this treatment? Thank you.

    1. Thanks for your question! The Phragmites stems are bundled together and cut, so that herbicide can be applied more efficiently. The herbicide is dyed green so that we know which bundles have been treated. Treating in late summer and fall is more effective because the plants take up the herbicide more readily.
