Buying Guide

Once you set out to find the best weed killer on the market, you should know exactly what you are looking for in a product. Some products only target certain types of weeds while others are only effective under certain weather conditions. That said, you need to consider some key factors when looking for the perfect weed killer for your lawn. Here are some essential tips to keep in mind before pulling out your credit card to try out a different weed killer.

Why should you use weed killers?

8 Excellent Weed Killers for Perfect Lawn and YardHaving a beautiful lawn offers many benefits. It improves the aesthetics of your houselands, you can get to plant some trees or flowers and you have a quiet space to enjoy a peaceful night. Maintaining such a beautiful lawn is, however, not a walk in the park. It will demand both time and effort from you. So, why should you use a weed killer?

  • To get more nutrients for your plants- Weeds also need the same nutrients, water and even light that your plants use. While the plants can share these nutrients, weeds tend to be more aggressive and grow at a faster rate. This means that you may have to get rid of some of the weeds that take the nutrients from your plants.
  • For a better-looking lawn- Weeds will compromise the quality and greenery of your yard or lawn. This is because they tend to thrive at the expense of other important vegetation in your lawn such as the grass. Using weed killers ensures that the weeds are not the only vegetation that thrives in your lawn.
  • Safety- Weeds are known to be harmful to certain types of plants. A lot of plants wither due to the overwhelming accumulation of weeds in the lawn. To ensure the other plants in your lawn grow safely, you will need to invest in a non-toxic weed killer. Weeds are also known to secrete harmful phytotoxins that hinder the development of other plants. Other weeds are harmful to humans and may cause skin irritation or allergies.

Types of harmful weeds to determine

Weeds are part of the gardening lifestyle. It is almost impossible to find a lawn that is weed-free at all times of the year. That said, you should know the type of weeds that you are dealing with. This will not only help you control the infestation but also find the perfect weed killer for your lawn. Here are the main types of weed.

  • Broadleaf weeds- These types of weeds have wide leaves that feature large veins and colorful flowers. You can find these weeds in places with low soil nutrients but it is easy to find them since their flashy colors make them stand out. They include dandelions, oxalis, clover, spurge, wild onion, plantains, and wild garlic among others. These weeds are quite prevalent in Northern US and you may have noted most of them growing in your lawn at least once. In the Southern parts, you will likely find clover, wild garlic, and wild onions as these are the most popular in the southern region.
  • Grassy weeds- These are weeds that grow as unwanted grassweeds. They include dallisgrass, crabgrass, goosegrass, creeping bentgrass, and quackgrass among others. Not all these types of grassy weed use the same killing products. Some weeds such as crabgrass are especially difficult to control. This is because the weed withers every time during the cold season but leaves thousands of seeds that sprout during spring. Using a pre-emergent weed killer such as the Andersons Pro Turf Barricade is a great way to deal with these notorious weeds.

How to use vegetation killers

8 Excellent Weed Killers for Perfect Lawn and YardHow you use weed killers will largely be determined by the size of your lawn. You should use a spray bottle after diluting the weed killer concentrate with water if you want to treat a small spot in your lawn. We, however, recommend that you get a spray tank if you have a larger area to treat. Some weed killers such as the Natural Armor Weed and Grass Killer come with trigger sprays to make the application easier.

One application is often enough in most cases. It is imperative that you avoid over-applying the herbicide even if it is considered non-toxic to your lawn. Too much weed killer can be harmful to your grass and other vegetation in your lawn or garden. Also, be considerate of the weather conditions during application. You should not apply the weed killer in the hot weather as dry grass is easily damaged by herbicides. Avoid applying the chemical on a rainy day too. Most products tell you how long it takes for them to be rainproof and if it rains within this time then

Features to consider while buying the best weed killer

Like buying other lawn products, you should not just buy the first product that you get. You should take some time to understand if it will work best for your lawn and if it meets your other needs such as budget etc. These are some of the factors that you ought to keep in mind when buying the best weed killer.

Price range

Everyone has some sort of a budget when looking to buy a product. Money may not be a problem but you must understand the standard price range of a weed killer. That said, this does not mean that you should rush to get the most expensive product on the market. Price only comes in after you have reviewed all other things that you want in a weed killer. We suggest that you list down your needs and compare them with the features of the products you are interested in. This will then allow you to carry out a cost-benefit analysis. However, if you are on a tight budget then you can check out the Compare-N-Save Concentrate Grass and Weed Killer 016869. This value pick works effectively and is great for larger areas too.

Weed killer types

8 Excellent Weed Killers for Perfect Lawn and YardYou may have noticed that there are different types of weed killers. There are pre-emergent weed killers such as the Espoma Organic Weed Preventer CGP25 and The Andersons Pro Turf Barricade. These weed killers are applied beforehand to prevent the weed from sprouting in the first place. Post-emergent weed killers, on the other hand, will target the weed killers that have already germinated.

There are also contact and systemic weed killers. Systemic weed killers are absorbed the leaves of a plant and travel to the root to kill the plant. It may take one to three weeks for you to start seeing results but they are quite effective. These types of weed killers are great for perennial weeds such as poison ivy, bindweed, ragweed, and even dandelions.

As the name suggests, contact weed killers will kill the weed as soon as it comes into contact with it. These weed killers are great for annual weeds such as crabgrass, mallow, bindweed, and nettle among others. They also work well for weeds that spread through seeds as they can kill the seeds when they come into contact with it. One thing that you might like about contact weed killers is that they only damage a small portion of plants if they accidentally fall on other plants. Unlike systemic weed killers that would kill the whole plant.

Covered area

You ought to first determine the area coverage that you intend to apply the weed killer on. Large lawns will have different quantity and quality needs from smaller lawns. If you are looking to eliminate weeds from a small area in your garden then you should opt for a ready to use formula that has already been mixed. On the other hand, a concentrated formula weed killer such as the Roundup Weed and Grass Killer Super Concentrate will work best if you wish to treat a lot of weeds in a large area. It is worth noting that the size of the package does not determine the area to be covered. Some weed killers are concentrated and only a little of it may work in a large area. Others may be diluted and use a large quantity of chemicals to cover a small area.

Selective or not?

8 Excellent Weed Killers for Perfect Lawn and YardAre you growing flowers or fruit trees that you want to keep? If yes, you need to make sure that you choose a weed killer that has the appropriate selectivity. In a nutshell, selective weed killers will only cause damage to the weeds in your lawn without killing any useful plants. They are suitable for flower beds, vegetable gardens or to kill dandelions in your lawn without harming the grass. You should always read the instructions on the packaging as some selective weed killers can still harm your grass.

Non-selective weed killers tend to destroy every plant that they are applied to without bias. These can work great for your patio, driveway or paving stones.

Active components

The active components of a weed killer can tell you a lot of things. It can tell you whether the weed killer is selective or not. It also lets you know the impact of the product on other plants or human life. Glyphosate is an active ingredient in many weed killer products such as Compare-N-Save Concentrate Grass and Weed Killer 016869. While this active ingredient is extremely effective at killing plants, it is harmful to other plants and to the environment.

If you want to use the weed killer in your garden then you should choose one  that lacks harmful chemicals. You can get one with natural ingredients such as the Espoma Organic Weed Preventer CGP25 or the Natural Armor Weed and Grass Killer.

Package volume

If you are looking for a larger package volume then you can try the Ortho Weed B Gon Weed Killer. It has a 1-gallon bottle capacity.

Spray, granular or others?

8 Excellent Weed Killers for Perfect Lawn and YardNot all weed killers are liquid or concentrated solutions. Granular weed killers like The Andersons Pro Turf Barricade or the Espoma Organic Weed Preventer CGP25 are made of solid particles that are applied like fertilizer to your lawn. Most granular weed killers act as pre-emergent weed killers that seek to prevent weed germination. It may be necessary to water your garden/lawn before using a granular weed killer. This is because they ought to be applied to wet weeds.

Liquid herbicides, on the other hand, are mixed with water to form an effective weed killing solution. The spray gets into the plant through its foliage and travels to the root to kill the plant. They are also more effective and give faster results since they are easily absorbed. Most of the products we reviewed were liquid weed killers except for the two stated above.

Clear instructions

Some weed killers feature toxic active ingredients and the last thing you may want is to apply it in the wrong way. Since you are dealing with a sensitive chemical, you need a product with clear user instructions. You need clear instructions about the mixing ratios. A significant number of products are liquid concentrate that should be mixed with water. A good product should help you know how much water you need and the specific coverage area that the solution can cover. It should also give instructions on how to apply it and any precautions to take such as knowing the right weather conditions. The Southern Ag CROSSBOW32 Weed & Brush Killer gives clear instructions that help the user apply it properly.

Ease of use

The ease of use is another important factor to consider before you get a weed killer. Avoid purchasing any product that has a complicated procedure when it comes to mixing and applying the solution. You mustn’t have a difficult time when preparing it and during application. This will help save time while also enhancing your safety and that of your lawn grass.

Effectiveness

You don’t want to get a product that is not effective at killing weeds. To ensure maximum effectiveness, you should first know the weed you are trying to control. This will ensure that you find the perfect weed killer that can effectively deal with it. Once you know the type of weed that is giving you sleepless nights, you can find an active ingredient that will kill it. For example, the Southern Ag CROSSBOW32 Weed & Brush Killer is known to be particularly effective with creeping Charlie. And while this makes it the best weed killer for Creeping Charlie, it won’t be effective on all weeds. Luckily, most weed killers will list the number and types of weeds that they can kill.

Safety precautions

Most weed killers are made for plants but you still have to exercise extreme caution when using them. They can cause irritation on the eyes or the skin if they land on your skin. They can also cause illnesses when ingested. With that said, it is important that you make use of protective equipment when preparing or even applying the product. It is also prudent to keep your children or pets away when applying the weed killer and only allow them when safe. Most manufacturers will indicate what length of time is necessary before your children can start playing on the lawn.

Organic weed killers such as Espoma Organic Weed Preventer CGP25 go the extra mile to prevent any harm to the environment too. These are a great option if you want to conserve the environment while getting rid of your weeds. It is, however, worth noting that organic weed killers are not as effective and you may have to dig deeper into your pockets.

FAQ
