You've found the best. Ditch the rest.

What is a weed?

In the most simple terms: A weed is a plant, bush, shrub or tree growing where you don't want it to. They sprout anywhere. From small to large, weeds are everywhere.

Why should I control weeds?

Weeds can damage concrete and if left unchecked can damage walls and even your home. They can and will damage your flowers and take over your garden.

Controlling weeds is a perfectly natural thing to do, it helps to know a little about the kind of weed you want to get rid of, they fall into 3 main categories:

Annual weeds.

Annual weeds live only for one year. Their purpose is to grow and spread their seed as far and as much as possible. They do this with the help of the wind, people, insects & pets. Try to kill these weeds before the lay seed. 

They will grow from seeds on any cultivated soil. Seeds can survive dormant for multiple years waiting to sprout when ideal conditions allow.

Annuals are relatively easy to kill and you can put them on your compost heap providing they don't have seeds.

Examples: chick weed, annual nettle, meadow grass & speed well.

Perennial weeds.

Much hardier and tougher to kill. Perennial plants can live for multiple years, they survive the winter seasons by storing nutrients in their roots.

If you don't get rid of all the root it may grow back as a whole new weed.

Examples: stinging nettles, dandelions, ragwort & creeping thistle

Woody perennial weeds.

Much tougher to remove and if left unchecked they can damage your property. Woody weeds like brambles, ivy & unwanted tree saplings.

Like other perennials you need to kill the whole root structure and stump to ensure they don't grow back.

Examples: brambles, ivy, tree stumps & saplings

Manual weed control

When controlling weeds you can either use manual work or chemicals to get rid of the problem.

For annual weeds you should try to kill them before they manage to spread their seed, using a hoe or gardening knife to cut them out. Identifying your weed is key.

For perennials you should pull or dig out the entire weed with a spade. Ensure you get the whole root structure or it may regrow.

When controlling weeds manually, prevention is the best cure. If you have cultivated soil that isn't being used then cover it, mulch it or plant in it otherwise they will grow.

Types of weed killer

Most gardeners look to use chemicals to control their weeds. Please ensure you always read the label with gardening chemicals.

Homemade weedkillers

There are many household chemicals that you can use as weed killer. They are for the most part effective but they can damage your soil and may only temporarily kill your weeds.

Does bleach kill weeds?

We don't recommend you use bleach as a weed killer, it may be illegal where you live but it is effective.

Does salt kill weeds?

YES! Salt is a great natural weed killer for paths and driveways. It may make your soil uninhabitable to plants though.

Does vinegar kill weeds?

Yes, vinegar is an excellent natural weed killer. It won't kill large weeds like brambles but it is effective.

Glyphosate weedkillers

Glyphosate is the worlds most used weed killer. It's used on farms and in gardens across the world. If used correctly it is one of the safest & strongest herbicides available.

It will kill almost any weed, plant, bush, grass or tree.

Triclopyr weedkillers

Triclopyr is commonly used for control of woody plants, including poison ivy, as it works better than many other kinds of herbicides for that purpose. It is a selective herbicide unlike Glyphosate, which means it will not affect grasses.

This can be a desirable trait depending on the site. Along with glyphosate, it is one of the more common herbicides used to control non-native invasive plants during habitat restoration.

There are two forms available, an ester form, and an amine form. The ester is much more likely to volatilize and move when applied during warm or hot conditions, and its use is typically reserved for colder times of year.

  • Peter Lucas says:

    Is this weedkiller still available ordered last week and have not received e mail confirmining delivery looked on another website and they said product no longer available

  • Al says:

    Gallop or similar high glyphosate 360g/1l brands will destroy horsetail & any other resilient weeds I’ve come across. Horsetail is rooted to resist & repel full extraction from it’s base & pulling or even using an implement will almost always result in a piece of root remaining to enable re-growth. Glyphosate 360 is systemic & has potency to engulf & kill root. Add a squirt of washing up liquid to sprayer with glyphosate & horsetail will be gripped tighter by weedkiller & even rain showers will have zero effect on efficacy of systemic process.
