Alternatively, residual weed killers will stop all plants from germinating, and non-selective weed killers will kill everything they encounter . Therefore, these are best used on patios or highly weed-ridden areas. The best weed killer will show visible results within 1 – 2 days. My advice is to look for a large capacity that will treat a surface area of at least 100 m² as these will generally offer the best value for money. Prioritise weed killers that kill the entire plant, including the roots, to prevent the weed from re-sprouting . To carry out my test, I chose two similar patches of weeds and treated one with Job done® Tough Ready to Use Weedkiller, and the other with the competitor product. To keep things as fair as possible, I chose patches that were close together and therefore in similar conditions, followed the instructions on each product, and treated both patches on the same day.

Be careful using weed killers around food plants. Many of them are unsafe for use around crops. There are some which are considered to be ok, but you should always do your own research on specific products and read the label carefully. There are a couple of reasons why this pump spray weed killer speeds up the process of getting rid of pesky weeds, and it comes down to both its effectiveness, and its straight-forward application style. This bottle contains 360 g of product, enough to cover a 1666 sqm area. It does require mixing before application, but it comes with a measuring cap included which is very easy to use. It can be applied using either a watering can or a sprayer.

Some weeds can be killed by simply pouring hot water over them. This can be effective on patios and driveways but will scald grass if used on the lawn. As a result, slightly more preparation is required than with ready-to-go weed killers. You’ll need to mix 15 ml of Weedol weed killer with 1 L of water in a watering can with a fine rose before applying it to the lawn.

Longevity: Any weed killers that needed to be reapplied after rain were significantly marked down, as this doubled the time you’d have to spend on weed killing.

The death of the sprayed weed can take up to 28 days, however, just one application can last a whole season. Once treated the area should not be dug or disturbed in any way, as the long-lasting control will be reduced. Whilst not all products can successfully get rid of pervasive weeds like horsetail, this WeedFree Plus weed killer causes it to turn brown in a couple of days. Other, more common weeds, can show signs of wilting within a couple of hours. Stopping Protein Production. Protein production is another essential element of plant growth and health. Some weed killers stop plants from being able to produce proteins. Ultimately this will kill weeds. Glyphosate works this way; however, do your research before using products which contain Glyphosate – is has been shown to have negative effects on health.

Introducing Different Hormones. The plant’s hormones dictate its growth. Some weed killers contain plant hormones that, when applied to the plant, confuse the plant’s growth system. This will kill weeds as the plant eventually becomes deformed and dies.
