There are weed killers designed for paths and patios, lawns, flower beds, vegetable gardens, and for general use around the garden. Some are fast acting while others take more time, not to mention the varying ingredients uses that produce different results depending on the weed you’re trying to kill. However, bear in mind that this is also a non-selective weed killer and incredibly potent. You don’t want to use this on a lawn unless you are looking to kill off all your grass along with the weeds, while care must be used when applying it on weeds that are near other plants. It comes as a concentrated liquid, so you need to dilute the weed killer before applying it to the garden.

If you choose to compost them , they need to be composted for at least 9 months before being suitable to use as mulch on the garden.

This is where weed killers come into play. Available for almost every type of weed, weed killers are usually liquid solutions that are applied directly to the weed to kill it. These contain any number of chemical ingredients that kill a part of the weed or the entire plant. 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.

They aren’t selective either, growing in almost every outside area of a home, including lawns, flower beds, vegetable boxes, pots, planters, handing baskets, and in and around paths, driveways, and gravel. Prevent weed seeds from germinating by using a weed killer that stays in the soil. This will stop weeds from growing, but will also stop any other plants from germinating as well. However, there are some other weed-removal options that you can consider, or that you might want to use alongside chemical weed killers:Selective weed killer is usually safe to use on lawns as it won’t kill off the grass. It will only target and kill specific types of plans (eg. weeds). Selective weed killer is normally clearly sold as being lawn safe. Therefore, if a weed killer doesn’t mention being safe for lawns, don’t use it on grass (unless you don’t mind the grass getting scorched). Here we will look at the ingredients of weed killers, based on what type of weed killer they’re most commonly used in. There are selective weed killers (only targeting certain plans), non-selective weed killers (not fussy about what plants they kill) and organic weed killers (using ingredients from nature).

Each tube provides enough weed killer to cover an area of roughly 20sqm, so a couple of tubes should be enough to eliminate weeds from most average UK gardens. The fact you just add the contents to water makes it simple to use, avoiding the hassle of measuring your own precise solution. The visible part of the weed above the soil stats to wilt and die in just 1-2 days, after which the roots absorb the remainder of the solution and are prevented from growing further. This kills the entire weed in about 2-3 weeks, with the visible portion already dead by this point. Pelargonic acid is the most commonly found active ingredient in organic weed killers. It’s a naturally occurring acid in geraniums. This acid is generally considered effective at controlling the growth of smaller broadleaf weeds (under 15 cm tall). This is not necessarily due to any shortcoming of the herbicide itself, but related to how plants absorb moisture. Most plants absorb more moisture in the cool temperatures of the early morning, but stop when temperatures rise in the afternoon.This weed control is exceptionally strong, with a single 2 L bottle treating up to 3332 sqm. It would be ideal for those with a badly overgrown allotment or garden, but it’s also a good choice if you’re after a super strong weed killer for deep-rooted weeds. Weed killers are every gardener’s friend. While some of us are better than others at growing shrubs and plants, all of us seem to be able to “grow weeds”. Thankfully, you can rid your lawn, patio, gravel drive, paths, and vegetable patches of these nuisance visitors using a range of highly effective and fast-acting weed-killer products. I tested various weed killers to identify the best of the best, so you don’t have to. I was looking for the most effective and eco-friendly weed killer, so I conducted a comprehensive test assessing the following factors:

Like most weed killers I’ve tested, this product does contain glyphosate which isn’t wildlife friendly. Flower heads should be cut off weeds first, especially dandelions. Safety and Environmental Impact: It was important to assess the overall environmental impact of each weed killer as well as the risk to the user’s safety. As a result, any product where the nozzle leaked was rated lower, as this risked harm to the gardener using it. Products with excessively harmful chemicals, such as Glyphosate, were marked down, as these pose a risk to wildlife. Ease of Application: When reviewing ease of application, I deemed any weed killer that came ready-mixed better for the average gardener, as less time will be spent preparing the solution. I also looked for products that came with different attachments – such as a nozzle and hose – to make application easier. Models with additional features, such as a built-in pressure pump and adjustable nozzle settings, were rated highest, as these elements made the product easier to use. Whilst Neudorff might not be a particularly well-known company, their WeedFree Plus Concentrate is a powerful weed killer that works on relatively stubborn weeds. Also, be mindful of their location in relation to other plants you have. If you’re controlling a flower bed or vegetable patch then you will want to choose a selective weed killer that won’t damage your plants. SafetyOne of the best things about this weed killer is that it’s fairly simple to apply. There’s a ‘flexi spray’ that clips out of the body, with the pipe clipping to the lid. There’s two spray functions, a jet spray and a fine spray. You will need to touch the nozzle, so gloves are required. Systemic weed killers are useful for those hardier weeds that take more effort to remove by hand, such as dandelions, thistle, and brambles. Selective and Non-Selective Not having to mix your own solution or use a watering can or spray bottle is very handy, while you can even refill the bottle once you run out, saving the cost of buying your own spray bottle or ruining a water can. Some weed killers start to work within 24 hours, while others might take a week to have much impact. Don’t be tempted to reapply without reading the instructions. If, after the quoted time, you still have persistent weeds hanging in there, there’s usually no harm in giving them another dose to finish them off. Is there an alternative?
