How Do You Mix Roundup?

Mixing Roundup is a simple process that can be completed in a few minutes depending on the amount being mixed. In order to mix Roundup, you need a non-galvanized container, water and the Roundup itself.

  1. Take note of safety precautions

    Examine your container of Roundup before you begin this process. Depending on the specific type you are using, there are different safety precautions on the label. Ensure that you are not doing anything hazardous and that your container size and material are appropriate for the chemicals you are handling.

  2. Calculate the amount of water you need

    Evaluate the area that you are treating with herbicide in order to estimate how much you need. If you are using Roundup Weed and Grass Killer Concentrate Plus, you need 1 gallon of water for every 3 ounces of herbicide. For the Super Concentrate formula, you need 1 gallon of water for every 1.5 ounces of Roundup. Roundup Pro requires 1 gallon of water for every 6.5 ounces of herbicide, and Roundup Concentrate Poison Ivy requires 1 gallon of water for 6 ounces.

  3. Add Roundup to the container

    Pour the amount of Roundup you need into your container carefully. Try not to let it spill out of its original container or the mixing container as it can be very dangerous to any type of plant.

  4. Pour water in slowly

    Add water to the container very slowly. If you see any foaming, stop pouring, and allow the foam to subside. Foaming occurs when the water is added too quickly.
