Gardening proves to be a great way for many individuals who find solace in these types of outdoor activities. Wet weather often stands in the way of making the most out of your gardening duties. Those who go the extra mile often get rewarded in kind by a garden that teems with flowers, plants, trees and so forth.

Having said that, there is one duty that most people hate when getting involved in gardening. We are talking about weeding. Weeds quickly spread all over your garden and are very invasive at the best of times.

What's more, they are in competition with plants for a growing space, sunlight, and nutrients. These factors alone make them an unwanted nuisance and requires a lot of work to eradicate them.

Anyone who was given the task of weeding will know just how back-breaking it can be to finish the type of task that takes hours to complete. Besides, it is only a temporary solution that makes a comeback every time.

Also, the bigger your garden, the more weeds you have to deal with. The weeds are not selective as they easily grow almost anywhere, whether it be on lawns, outside areas, vegetable boxes, flower beds, planters, and even driveways.

You can honestly say that there isn't an area in your garden that will escape weeds. They have a knack of ruining the appearance of your garden. Do not forget that they have the potential to limit the growth of flowers and plants.

This is where weed killers come in handy. You get brands that will deal with almost every type of weed. Most of these take on a liquid form, making it easier to apply it directly to the area in need of treatment. Some would kill part of the weed and others the entire plant.

You get weed killers that you can use before weed has half a chance to make head way. You will find there are weed killers that you can use to kill them off before they get a chance to develop.

Gardeners find weed killers to be the most useful tool ever. One thing is for sure, your back will thank you for making use of weed killer instead of having to bend down to get rid of them.

It is only a matter of time before your garden would be weed-free.

Weeds grow depending on the prevailing conditions in different areas. Each atmosphere stimulates the production of a specific plant. The weeds on your lawn are different from the weeds in your garden. Some can be easily to get rid of due to shallow roots while others are deeply rooted, making it difficult to control weeds and grass build up. It is best to take note of the area of use before you agree to buy the turf herbicide. Some herbicides may be strong and not good for use in the proximity of homestays or animal shelters.

It is very handy not having to mix your own solution or use an irrigation can or spray bottle while you can refill the bottle once you are done with it, save on purchasing a spray bottle or ruin a water can.

The spray extends to wide areas, such as patios and entrances, but it is also accurate, so weeds that grow alongside other plants can easily be targeted. Just be sure the solution you mix does not accidentally brush sides with the flowers or plants.

It is also a very quick acting weed killer, which requires approximately 24 hours to start producing results. You could use it on all of the yearly weeds and common perennials that invade your garden, though it may take more time to kill those bigger and tougher weeds.

The solution offers adequate protection for up to 160 square metres. Therefore, you will probably get more than enough use out of the weed killer before you need to refill it.

Deadfast PTO0010P Concentrated Weed Killer Sachets, 12 x 100 ml,Black
  • Systemic concentrated weedkiller
  • Action kills both above and below the ground

It's also possible to use a single sachet on a plant, but you won't get quite the same amount of coverage anywhere. Still, there are instances where you may need a potent weed killing alternative to get rid of a stubborn weed – say like big bramble growths on a tree stump to annihilate it.

If you have a massive area, such as a terrace or walkway, with heaps of weeds, then these sachets genuinely come into their own. Only add the sachet to the watering bottle, or spray it, and administer the weed killer properly.

The effects may take a little time to make a difference, with the weed killer taking approximately 1-2 weeks to find its way through the exterior extremities and then through the weed plant. Significantly larger weeds could take more time, so be patient at all times and let the weed killer do its thing, as this may take up to 4 weeks to control.

Be aware that rainfall will reduce the weed killer's effectiveness, so if it rains within six hours you can need to apply it again.


  • 12 sachets will cover an area consisting of about 720 square metres should you make use of a sprayer
  • Non-selective and systematic for handling different weeds
  • You can dilute it with water or apply it directly on weeds

One downside is that since most people use the watering method it will not be as accurate , especially if you do not want to damage areas with many plants. If you want a more detailed application then investing in a spray bottle is a good idea!

Weed Killer Buyers Guidelines

There are numerous weed killer products on the market, making it hard to know which one is the best buy for your garden. Another thing to pay attention to is that each product serves a different purpose. Some of these will get rid of all weeds, while others require selectivity.

You will come across weed killers that are suited to eradicate weeds from lawns, patios, paths, vegetable gardens, and other areas around the garden.

Some of these are fast acting compared to others that take more time. Then, there are the varying ingredients that deliver different results that largely depend on the type of weed you are trying to eradicate.

It is all too easy to become confused with the various weed killer options made available to British Gardeners. To make the process quicker, you would do well to follow buyers guidelines before heading out to purchase weed killer for your garden.

Types of Weed Killer

You will find all sorts of weed killers that feature a variety of ingredients and produce different results. It helps to learn more about the different products available and their various uses. This way you can make the right choice and pick something that matches your needs.

Let's discuss two main types of weed killers

Pre-emergent and post-emergent. As the names imply, you would use these weed killers either before or after the weed made itself visible.

The predominant weed killer is the post-emergent. You only notice them when they are grown and taking over areas of your garden.

Pre-emergent, on the other hand, is ideal for when you wish to prevent weed growth. You can use it when you're busy planting or sowing during the growing season.

Contact Weed Killer

These are the types of weed killers that will eradicate the plant the moment it gets in touch with it. They are commonly found in spray bottles. All you need to do is apply it to the weeds in your garden or driveway and wait for it to die.

You can expect much quicker results, but these are not all that long-lasting. The reason for this is that the chemicals would only target the portion of the weed that is above the ground.

In most cases, contact weed killer will only deliver results in a couple of hours time. You will notice that wilting takes place soon after application. The weed will stay alive for a couple of weeks before they eventually die off.


These are the type of weed killers that are more potent than contact weed killers. Even though it gets applied in a similar manner, the key difference lies in the fact that the chemicals given off are taken in by the foliage of the weed so it is transported to the roots.

Therefore, the entire weed will die, root and all, and future growth is not possible. Unfortunately, it takes longer than contact killers to eradicate weed. It is very useful for dealing with harder weeds that will involve more effort to get rid of, such as thistle, brambles, and dandelion.

Non-Selective and Selective Weed Killers

All the weed killers we discussed over here are either non-selective or selective. The selective weed killers will only be effective on certain weeds while non-selective will kill just about anything you put it in touch with, including fruits and veg, flowers, plants, and grass.

The selective type is excellent for when you treat flower beds and lawns against weed infiltration. This way your precious plants are not at risk of getting killed in the process.

While non-selective weed killers are super effective, they are also risky in that these randomly kill plants.

Tips to Help Your Choose the Right Weed Killer Type

The esthetic value of your garden is reduced by weeds. So, when they sprout, you will get rid of them. Some amateur gardeners face a challenge since certain grass killers and weeds are not unselective. These herbicides will damage the grass that you tendered for years. Therefore, the best weed killers for lawns must be identified to avoid damage to your lush turf. We understand that you want to destroy the weeds on your turf with little to no disorder. In addition to distorting your lawn's elegance, weeds will also rob the grass of its nutrients and space for growth. Keep your lawn clean with the support of a zero turn lawn mower

You will now have a better idea of what you might need for your garden, knowing the weeds killer type available. See some of these hints for a good weed killer:

Form of weeds

In the garden, which kind of weeds do you deal with? You may need to have a systemic weed killer, if it's hard permanent weed such as yarrow, dandelion, creeping buttercup, or yarrow, whereas annuals can be dealt with using a contact killer

Take note to see if several weeds or large quantities of a single type are visible. If there are different weeds, make sure you opt for a non-selective weed killer!

Place Where You Will Find Weeds

Check the weeds in your garden and select a proper weed killer. You want a selective weed-killer so the grass doesn't fade away in the background, if the weeds are on your lawn.

In addition, weed killers are intended for certain areas. For starters, the weed killers on the patio and on the driveway help to destroy the weed that occur between cracks.

Also, be mindful of its role with regard to other plants. You want a selective weed killer, which doesn't damage your plants, to be selected if you control a flower bed or vegetable patch.


Note that weed killers use a mixture of chemicals that are often hazardous to touch. Therefore, please test to see how safe they are to use.

Some are suitable for pets and kids, ensuring that if anyone enters the area soon after application, they will not harm them. Be aware that stronger weed killers are more toxic, so keep reading the safety information before buying.

The effects may cause a weed to become unsafe. Some weeds can be removed quickly by weeding or tearing them away. Others are stubborn and it proves useless to attempt to uproot them.
