Roundup Weed & Grass Killer₄ with Sure Shot Wand is a versatile herbicide ideal for tackling tough weeds, including dandelions. It's designed to be used in various locations such as flower beds, around trees, and on walkways.

One of its strengths is the rapid action: it's rainproof in just 30 minutes and shows visible results within hours. The Sure Shot Wand helps target weeds accurately, minimizing the risk of affecting other plants, which is a significant advantage for those maintaining a garden or landscaped areas.

Scotts Turf Builder Weed & Feed3 is a combination weed killer and lawn fertilizer designed to control dandelions and various other weeds while nourishing your lawn. This granular product is effective against over 50 types of weeds and is suitable for multiple grass types, including Bahiagrass, Bermudagrass, Bluegrass, Centipedegrass, Fescue, Ryegrass, and Zoysiagrass. Its active ingredients, 2,4-D and Mecoprop, are potent herbicides that target weeds effectively.

A single 14.29 lb. bag covers an area of 5,000 square feet, making it suitable for medium to large lawns. The best time to apply this product is when weeds are actively growing, and temperatures are between 60°F and 90°F, ensuring optimal results. However, it is not available for purchase in Florida, which could be a drawback for residents in that state. Additionally, the granule form requires the lawn to be wet at the time of application, which might necessitate careful timing around weather conditions.

While the product claims to thicken the lawn by crowding out future weeds, users should be mindful of its chemical composition and consider safety precautions if they have pets or children frequently using the lawn. This product is not rainfast immediately, so avoiding application before anticipated rainfall is advised to ensure effectiveness. Considering these factors, Scotts Turf Builder Weed & Feed3 is a robust solution for those looking to combine weed control with lawn fertilization, particularly in regions where the product is available.

Buying Guide for the Best Dandelion Killer

Choosing the right dandelion killer can make a significant difference in maintaining a healthy and beautiful lawn or garden. The key is to understand the different types of dandelion killers available and how they work, so you can select the one that best fits your specific needs. Here are some important specifications to consider when picking a dandelion killer.
Type of Dandelion KillerDandelion killers come in various types, including selective herbicides, non-selective herbicides, and organic options. Selective herbicides target dandelions and other broadleaf weeds without harming grass, making them ideal for lawns. Non-selective herbicides kill all plants they come into contact with, which is useful for clearing areas completely but not suitable for lawns. Organic options use natural ingredients to kill dandelions and are safer for the environment and pets. Choose a selective herbicide for lawns, a non-selective one for areas where you want to remove all vegetation, or an organic option if you prefer an eco-friendly approach.
Application MethodDandelion killers can be applied in different ways, such as sprays, granules, or concentrates. Sprays are easy to use and allow for targeted application, making them great for spot-treating individual dandelions. Granules are spread over a larger area and are useful for treating entire lawns. Concentrates need to be mixed with water and applied with a sprayer, offering flexibility in application strength. Consider how much area you need to treat and your preferred method of application when choosing between these options.
Active IngredientsThe active ingredients in dandelion killers determine their effectiveness and safety. Common active ingredients include 2,4-D, dicamba, and glyphosate. 2,4-D and dicamba are often found in selective herbicides and are effective against broadleaf weeds like dandelions without harming grass. Glyphosate is a non-selective herbicide that kills all plants it contacts. If you are treating a lawn, look for products with 2,4-D or dicamba. For clearing areas completely, glyphosate is a strong option. Always read the label to understand the active ingredients and their safety.
Coverage AreaThe coverage area indicates how much space a product can treat. This is usually measured in square feet or acres. Smaller bottles or packages are suitable for spot treatments or small lawns, while larger containers are better for extensive areas. Estimate the size of the area you need to treat and choose a product that offers adequate coverage. Overestimating can lead to waste, while underestimating may require multiple applications.
RainfastnessRainfastness refers to how quickly a dandelion killer becomes resistant to being washed away by rain. This is important because if it rains soon after application, the product may not be effective. Products with a shorter rainfast period are more convenient, especially in areas with unpredictable weather. Check the label for rainfast information and choose a product that suits your local climate and weather patterns.
Safety for Pets and ChildrenIf you have pets or children, their safety is a crucial consideration. Some dandelion killers are safe for pets and children once they have dried, while others may require a longer waiting period. Organic options are generally safer but may be less effective. Always read the safety instructions on the label and choose a product that aligns with your household's needs. If safety is a top priority, opt for products specifically labeled as pet and child-friendly.
