It covers up to 300 square feet per gallon when mixed according to directions, making it an efficient option for larger areas. However, it is important to use it carefully to avoid damaging desired plants and to follow the booklet instructions precisely for optimal results. While it has a strong environmental impact due to the active ingredients like Triclopyr and Diquat Dibromide, caution is necessary to minimize any adverse effects.

Ortho GroundClear Year Long Vegetation Killer1 Concentrate is a potent herbicide designed to tackle a wide range of weeds and grasses, making it a versatile option for those looking to maintain weed-free areas. Its standout feature is its long-lasting residual activity, effectively preventing regrowth for up to a year, which is beneficial for users seeking a low-maintenance solution. The fast-acting formula begins working immediately, killing weeds down to the root, ensuring comprehensive removal when used correctly.

This makes it particularly effective for use in areas with persistent weed problems like driveways, sidewalks, and gravel areas. Application is straightforward with a tank hose sprayer, mixing 24 fl. oz. of concentrate per gallon of water to cover up to 1,600 sq. ft., making it suitable for medium to large areas. However, potential users should consider its environmental impact, as such powerful herbicides can affect surrounding non-target plants and soil health.

The main active ingredient, Imazapyr, is known for its long-term soil activity, which might not be ideal for those looking to plant in treated areas soon after. Additionally, while it ranks well in its category, the product dimensions and weight suggest it is relatively easy to handle, but the coverage might require multiple treatments for larger properties. The Ortho GroundClear is best suited for users who need a robust, long-term weed control solution in non-cultivated areas, but should be used with caution regarding environmental and soil considerations.
