What Type of Weed Killer Should You Use on Horsetail Weed?

You should always consult with the manufacturer’s instructions when using weed killer. It can be harmful to pets, humans, and even your lawn if used improperly. In addition to safety concerns, weed killers will not be effective if used incorrectly. If you find that weed killer is not effective in killing weeds, this could be caused by a variety of things.

One of the most common reasons weed killer is not effective is because it is improperly mixed. Pay close attention to the manufacturer’s recommended mixing strength and mix accordingly. Over-concentrated weed killer will be effective but is a waste of money and a greater health concern. Under-concentrated weed killer is likely not going to kill the weeds. Other times, weed killers are not effective because they do not have ample time to soak into the plant and dry.
