Ortho GroundClear Weed and Grass Killer with Comfort Wand works amazingly well, easily eliminating dandelions, chickweed, and other stubborn weeds.

The Ortho GroundClear Weed and Grass Killer is a versatile herbicide that targets a wide range of weeds including dandelions, chickweed, and crabgrass. It uses ammonium nonanoate as its active ingredient, which provides fast-acting results within 15 minutes and becomes rainproof after 2 hours of drying. This is particularly useful for maintaining patios, driveways, and landscape beds, though it is not suitable for use on lawns or other desired grasses.

One notable feature is the Comfort Wand applicator, which helps with precise application, reducing the chances of affecting nearby plants you want to keep. The product covers up to 5,120 square feet with its 1-gallon container, making it quite efficient for larger areas. However, it’s important to note that this herbicide is non-selective, meaning it will kill any plant it comes into contact with, so careful application is necessary.

Additionally, while it’s OMRI listed, indicating it's safe for organic gardening, users concerned with environmental impact should be mindful of its potential effects. The key drawbacks include its non-selective nature and the need for careful application to avoid damaging desirable plants. This product is best suited for individuals looking to tackle tough weeds and grasses in non-lawn areas quickly and effectively.

Weed Spectrum
Truly does work to kill weeds growing through rocks in the front yard.

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.

Buying Guide for the Best Herbicides

Choosing the right herbicide can be crucial for maintaining a healthy and productive garden, lawn, or agricultural field. Herbicides are chemicals used to control unwanted plants, commonly known as weeds. The right herbicide will help you manage weeds effectively without harming your desired plants. To make an informed decision, you need to understand the key specifications and how they align with your specific needs. Here are the key specs to consider when selecting a herbicide:
Type of HerbicideHerbicides can be classified into two main types: selective and non-selective. Selective herbicides target specific types of weeds while leaving other plants unharmed, making them ideal for lawns and gardens where you want to protect certain plants. Non-selective herbicides kill all plants they come into contact with, which is useful for clearing areas completely. Choose selective herbicides if you need to protect certain plants, and non-selective if you need to clear an area entirely.
Mode of ActionThe mode of action refers to how the herbicide affects the plant. Systemic herbicides are absorbed by the plant and move throughout its tissues, killing it from the inside out. Contact herbicides, on the other hand, kill only the parts of the plant they touch. Systemic herbicides are effective for perennial weeds with deep root systems, while contact herbicides are suitable for annual weeds and quick results. Consider the type of weeds you are dealing with and their growth patterns when choosing the mode of action.
Application MethodHerbicides can be applied in various ways, including sprays, granules, and liquids. Sprays are easy to apply and can cover large areas quickly, making them ideal for lawns and fields. Granules are spread over the soil and are activated by water, which can be useful for pre-emergent weed control. Liquids can be mixed with water and applied directly to the soil or plants. Choose the application method that best fits your area size, weed type, and convenience.
Residual ActivityResidual activity refers to how long the herbicide remains active in the soil after application. Some herbicides break down quickly and have no lasting effect, while others can remain active for months, preventing new weeds from growing. Short-residual herbicides are suitable for areas where you plan to replant soon, while long-residual herbicides are ideal for areas where you want prolonged weed control. Consider your planting schedule and the need for long-term weed prevention when selecting residual activity.
Environmental ImpactHerbicides can have varying levels of environmental impact. Some are designed to break down quickly and have minimal impact on the environment, while others can persist and potentially harm non-target plants, animals, and water sources. Look for herbicides that are labeled as environmentally friendly or have low toxicity if you are concerned about the impact on your surroundings. Consider the proximity to water sources, wildlife, and other sensitive areas when evaluating environmental impact.
Weed SpectrumThe weed spectrum refers to the range of weed species that the herbicide can control. Some herbicides are broad-spectrum and can control a wide variety of weeds, while others are narrow-spectrum and target specific types. Broad-spectrum herbicides are useful for general weed control, while narrow-spectrum herbicides are better for targeting specific problem weeds. Identify the types of weeds you are dealing with and choose a herbicide that effectively targets those species.
