What to Look for in the Best Weed Killers

While shopping for gardening equipment, many people tend to order cheap products that do more harm than good. With low-grade weed killers, for instance, many people have burned their lawns to a crisp. Other have failed to get good results after many tries, which is frustrating. To clear a heavy weed invasion on your lawn professionally, use these tips to get the best weed killer:


While shopping in a hurry, people tend to order low-quality weed killers that fail to deliver. Before reaching for your wallet and buying a bottle or two, evaluate the effectiveness of your product of choice. Which type of weeds can it kill permanently? If you have clovers or any other broadleaf weeds on your lawn, buying a product that only kills grasses is a wrong decision. A brand that is effective against the species of weeds that you are struggling with will serve you well. However, if possible, shop for a broad-spectrum weed killer that is effective against most non-beneficial grasses. They deliver the best results.


Weed killers are of two broad types – concentrates and ready to use ones. Both have pros and cons that you should check out before reaching for your wallets. Concentrates, for instance, are not only affordable but also very flexible. You can experiment with different concentrations until you find a formula that works the best for your lawns. Unfortunately, people who are not good with measurements find them hard to use. As their name suggests, pre-mixed weed killers are ready to use. Brands such as Roundup 5725070, for instance, come in convenient spray containers that you can use off the shelf. However, they tend to cost more than some concentrated weed killers do.


While shopping for a weed killer for routine weed management at home, never gamble with the safety of your kids. Check the type of ingredients used to produce your weed killer of choice. Are they organic? Do they contain chemicals that might harm the environment or your children over time? If you cannot find a natural weed killer such as Espoma, look for a safe alternative that works well. Check its label to determine the type and the quality of the ingredients used to make it. You can also read online reviews to have an idea of the experience most people have with your weed killer of choice. If most people report irritation and other health issues, look for another weed killer.


Manual weed pullers are suitable for clearing weeds on small lawns. However, if you have a large garden, you need an effective broad-spectrum remedy such as a weed killer. Their liquid or granulated formulae are easy to use. They are also effective against most species of weeds and are therefore suitable for routine management of lawns. These top 10 brands are the most dependable.
