Weedkillers for gardeners (Adobe Acrobat pdf document outlining weedkillers available to gardeners; see section4) Links With glyphosate as its primary ingredient, this product does need to be handled and used with care. It’s toxic to pollinators and pond life, and children / pets need to be kept off the treated area until it’s dried. It does take a while to dry – up to 48 hours. Like many off-the-shelf weed killers, it contains glyphosate. While this is strong enough to kill weeds, it’s also strong enough to harm pollinators and pond life. Having said that, treated areas can be replanted 7 days after application, which isn’t bad going for a weed killer. Hoeing: Run a hoe over a bed or between rows to kill most weed seedlings. For maximum effectiveness, choose a dry day with a light wind, so that the seedlings will dry out on the surface of the bed rather than re-rooting into moist soil 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).

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: This has become a reliable product over the years. Well known for its strength and qualities as a systemic weed killer. Although there is only a litre, you’ll effectively treat over 300m2 from my personal experience. The sales pitch is that you’ll get 416m2 but I tend to use it for tough weeds that need re-application a few days later to ensure the leaf is able to absorb enough to get into the plant, right down to the roots.For the Roundup things are much more straightforward being a ready mix weed killer however they are very vague about coverage so I worked this out to be about 1.5-2 litres needed. Roundup– going to use 2 litres max in this test based on 60m2 The Gallup Home & Garden Weed Control has been promoted as the strongest weed killer available for domestic use, and it did work very well.

SBK Tree Stump Killer comes as a 250 ml concentrate, which states that it’s capable of treating up to eight stumps. However, large stumps will likely require repeat applications, so this number is reduced. Using a tree stump killer can make it easier to remove. There are a few different types of product to choose from, and choosing the best tree stump killer will depend on your own preferences as well as the size of the stump. The concentrate requires diluting, regardless of whether it’s applied directly to stumps or used with a sprayer. Dispensing the product can be a little challenging, as the design of the bottle means it measures out some liquid first, and then you remove the cap.

Now I’m well aware this isn’t designed for trees and shrubbery but I thought I’d give it a go anyway. Since from the first two tests I have established Gallup is seriously strong, I thought I’d give it a go on this shrub growing out of my French drain. If it doesn’t work I’ll cut it off and use some tree stump killer. Here’s how that came out: Gallup killed the leaves after a few weeks but I don’t think it’s fully dead Best results are achieved when time is spent applying this product liberally and deliberately to plants, and it may not work just to just generally spray the solution near them. Cutting the plants down to stumps first is the best way to get the most from this tree stump killer. Pumping the handle creates pressure in the container, and when the button on the wand is pressed, the weed killer travels through the hose and out of the nozzle. The output can be adjusted, producing either a spray or a fine jet. In terms of its effectiveness, this product works well on woody growth – particularly ivy. As mentioned, several applications may be needed when treating tree stumps.It seems to work best in hot, dry weather, and certainly shouldn’t be applied when rain is forecast for the same day; the longer the weed killer stays on the weeds, the more effective it will be. The Weedol Ultra Tough WeedKiller Liquid Concentrate is arguably the easiest weed killer to apply of all the ones I tested. It doesn’t come pre-mixed, but it can be diluted in either a watering can or sprayer. Here’s a look at the Gallups bramble and thistle patch after I’ve sprayed it and a couple of weeks has now passed, I haven’t seen good enough results on Weedol and Roundup to document yet. I’ll update when I can: Gallup started to wilt bramble after a couple of weeks The biggest disadvantage of using Solar Bay Copper Nails is that they work slowly and are not necessarily as reliable as chemical methods. I went home and followed his advice, and wouldn’t you know it, this time it worked wonders. So, if ever you’re having problems getting a product to work as expected, keep my little story in mind. You don’t want to apply weed killer in wet conditions as it will be washed away and run off, but you also don’t want to spray in drought conditions without watering the weeds a little first.

You’ll need to get fairly close to the weeds to cover them, and those with weaker hands or reduced mobility may find they’re working harder than is comfortable for them. Apply a tough formulation of glyphosate (e.g. Roundup Ultra or Doff Weedout Extra ToughWeedkiller) to the foliage of the section you want to kill. Alternatively, cut canes to the ground and treat with a stump and root killercontaining glyphosate (e.g. Roundup Stump Killer, Doff Tree Stump & Tough Weedkiller orWestland Resolva ProTree Stump killer).

If the product also killed the roots within a 2-week window, this was also deemed highly effective. I marked down any weed killers that took 7 days to show the first signs of success, and those that took even longer received the lowest rating.
