Best Strong Weed Killer

Nothing can be more off putting for a gardener than the sight of weeds. Invasive and unattractive, the sight of weeds in a garden is enough to drive most people mad, and that’s before they spend an age trying to remove them!

Thankfully, many weed killers are widely available, making life that bit easier for anyone trying to remove a weed infestation throughout the garden. Unfortunately, not all weed killers can get the job done, especially those that are sold in supermarkets and garden centres.

When a standard weed killer isnt doing the job, it may be necessary to get something stronger to tackle the problem. Industrial grade weed killers are some of the most effective herbicides available today, so when a normal weed killer isn’t cutting it, you may want to look for this stronger alternative.

The Benefits of Strong Weed Killers

You’ve likely seen strong weed killers in action before, as they are widely used in public areas to help remove any problematic weed outbreaks. From residential arears to city centres, strong weed killers are used by professionals to great effect, and it is something you yourself can use at home.

For the most part, these stronger weed killers are glyphosate-based, a form of systematic weed killer that seeps into the plants entire system to kill it from within. This is highly effective as it kills both the foliage and the root of the plant, preventing any regrowth’s from occurring.

A great advantage of this type of weed killer is that it is unharmful to soil. Should the herbicide come into contact with soil on the ground, then it simply biodegrades and forms a natural substance that will not cause any harm to the soil – this isn’t always the case with other types of weed killer.

Recommended Strong Weed Killers

For the most effective results in your garden, we recommend investing a strong industrial grade weed killer. They differ from conventional weed killers as they are sold as concentrates, meaning you will need to prepare the weed killer yourself, so you will want to get a garden sprayer to administer the herbicide.

Be sure to get a new sprayer however, as it is a bad idea to use one that was previously used for spraying fertiliser!

Here are some of the top strong weed killers available today:
