    Q: will this work on ornamental bamboo

    13 days ago
    1 Answer
    • AI-generated, Human-approved
      A: Yes, this product is effective against bamboo, though it requires specific application. For best results, mix the concentrate half and half with water, cut the bamboo, and immediately spray the remaining stump. You may need to repeat this process throughout the summer to treat new growth from rhizomes.

    Q: Do I need to use a surfactant ?

    16 days ago
    1 Answer
    • AI-assisted, Human-approved
      A: No, you do not need to add a surfactant because it is already premixed into the formula. While the product includes it to help the herbicide stick to plants, some reviewers suggest adding a small amount of dish soap for better adhesion on slick vegetation.

    Just my 2 cents

    a day ago
    Works great on most grass and weed but the thorny blackberry does not work. Have to be patient, results takes almost two weeks to see.

    Yes, I recommend this product.

    Really good weed killer

    8 days ago
    It's a great weed killer. Make sure you use PPE and whatever you spray you want dead. After a week you will see whatever you spray wil wilt and die.

    Finally, Something that Works!

    This worked perfectly. I hope the formulation does not change! I have tried many products and been disappointed when the formulation changed (Ortho - listening?). This took about a week all told to completely kill everything, which is just what I wanted.
