The Elixir Gardens Barclay Gallup Weedkiller comes in a tub, and the un-diluted product can cover an immense area of 3332 meters. We also like that the killer is broken down and inactivated when it makes contact with the soil, so no lasting damage is done to your lawn or treated sections.

How to Choose Weed Killer

You can see that there are many weed killers to choose from if your garden needs a little love and care, making it a little difficult to pick the right one. Don’t worry, though! We have created a practical buying guide with the main considerations to look at when selecting these products.

Available Surfaces

Firstly, think about where the weeds are on your property. Are they infesting a driveway, paths, or patio? Perhaps there is a growth on your grass, flower beds, or borders? This distinction is important as different products are better suited for certain surfaces.

For example, you can get a specifically designed solution for gravel and patios. Alternatively, specialist items are meant to be used only on grass. Look at where your weed problem is, and choose the appropriate killer.

Volume

Next, you must consider the capacity of the container. Usually, these products come in a liquid form and thus are measured in litres. The packaging or product description often states what area in meters the fluid should cover.

Check this out, and see if the volume suits the surface you need to cover. For example, if you have a larger lawn or a severe weed problem, you may need to purchase multiple products to eradicate the issue properly.

Usability

How easy the product is to use is also something to think about. There are generally three types of weed killer – spray bottles, containers with a hose attachment, and pellets/granules. Each one has pros and cons for how easy it is to operate and distribute. 

The spray bottle is the easiest to use and works like a regular cleaning product. Simply open the nozzle, and pull the trigger to release the fluid.

Next, we have the container with a hose – this is similar to a squirt bottle, but a pipe connects from the unit to the nozzle. You hold the item in one hand and the spray head in the other. There is then either a trigger or pump to release the liquid. These are a bit more tricky to use, but they still give great control.

Lastly, there are weed killers that have a pellet or granule formula. These are simply shaken onto the ground or supplied with a scooper. 

Health & Safety

This is an essential factor, especially if you have children and pets. Weed killers contain dangerous chemicals that destroy organic material. As a result, they are often highly potent and can cause health and safety problems.

Always check the suitability and instructions for use. The product will clearly state if it contains harmful substances and if you must keep children and pets away after using it. Look at the instructions for safe use, too – often, wearing gloves is advised, for example.

Effectiveness

Lastly, you want a weed killer that works! These products are known to be inconsistent so picking an effective treatment is essential. Usually, the item describes clearly the types of infestation it works on. Also, it often states the best time and conditions to use it. Make sure you read the info carefully so that you choose a killer that is suitable for the problems you have.

Summary

Our top pick is the Roundup 119407 weed killer. This excellent product benefits from a simple usage process, effective results, and suitability for numerous surfaces. This item should work between one and two days to eradicate those annoying infestations. It is incredibly easy to operate due to the one-touch trigger, and the extendable hose also means you don’t have to bend down to apply the liquid.
