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. 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. The nozzle can be twisted to select either a ‘jet’ or a mist; however, the mist is not particularly fine. The jet, on the other hand, can be used as expected to sufficiently target individual weeds. 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. Pet safe weed killers are only really safe once they have dried out, so it’s important to know how long that takes. Most top, glyphosate-based, pet friendly weed killers will take quite a few hours to dry out, whereas organic compounds can be dry within as little as 15 minutes. How long before you can replant?

Value for Money: When assessing value for money, I identified how many litres of weed killer you received, the treatment area it covers, and the price point. Products that covered a higher surface area and still retained their effectiveness (for example, a 2 L bottle able to cover over 3000 sqm) were rated higher than those that only covered a smaller surface area for the same – or similar – price. I also assessed the additional features that come with a weed killer, as these products give you better value for money. Resolva 24 hour is called so because the makers claim that you’ll see results in 24 hours. Well, I can’t agree with that exactly, but it did start to have an effect after about 48 hours and within 4 days it was certainly noticeable. We tested this product about 3 weeks ago, and those weeds are still nowhere to be seen, so full marks there. Something I wasn’t so keen on was the odour of this weed killer. It wasn’t horrendous, but you could never call it pleasant either, and it was quite strong. On the plus side, the fact that this product isn’t left in the ground means that the treated areas can be sown or planted again relatively soon after using the product.

With some products being more pet and environmentally friendly than others, but then not quite having the weed killing performance of the more toxic products, it can be hard to decide on what makes the best pet friendly weed killers. 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.

One 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. You do, however, need to be careful it to spray it on your lawn or other plants that you wish to keep alive as it will damage them. Weedkil’s child and pet friendly formula is probably the most environmentally friendly of all the products we reviewed. 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.
