How to buy the best weed killer
When it comes to buying the best weed killer, there are a few factors worth bearing in mind to ensure you choose the right product to achieve the outcomes you're after. To help you out, we've listed some of these, as well as some frequently asked questions.
Immediate results or slow and steady?
If you're using a weed killer on your garden path ideas, driveway, or an area where you're not too concerned about affecting surrounding plant life, there's no problem with choosing a fast-acting solution that will stop weeds in their tracks. However, you may want to opt for a slightly longer-term solution – take a look at the fertilisers we've included above – if you're looking to eradicate weeds without affecting the rest of your lawn ideas.
Large grounds or small plot?
If you're looking to spot treat the weeds in your garden, you may be able to get away with choosing a small spray bottle, whereas a fertiliser or a weed killer with a hose attached may be a better solution for larger spaces.
Fertilise!
If you're looking to eradicate your lawn of weeds in the long term, it may be worth opting for fertiliser, which will help your grass to grow back thicker and fuller, preventing weeds from growing back in the process.
What is the best weed killer?
No, it's not a silly question. In fact, it couldn't be more important. A little annoyingly, there is no straightforward answer. While we do have a personal favourite, the Resolva Ready To Use Weedkiller, commendable for its spot-treating capabilities, it's certainly not a go-to for someone requiring an all-in-one fertiliser and weed killer. For the latter request, we'd suggest the EverGreen Complete 4-in-1 Lawn Care, Lawn Food, Weed and Moss Killer, which rids gardens of weeds but also nourishes lawn growth. Really, it comes down to your criteria. So, in terms of finding the best weed killer, we'd suggest reading our list, making sure to check which product is attributed best for which function. And if you're still a little unsure, check the specs and info, too.
How do you kill weeds and prevent them from coming back?
Ah yes, the age-old question. Nowadays, we're a lot more clued up on how to get rid of weeds. Firstly, you'll want to note which weeds are particularly rife in your garden; this way you can pinpoint them with a specific plan of attack. For example, if you have a dandelion, daisy or clover infestation, the Weedol Lawn Weedkiller is a trusty choice indeed.
Other essential components of the de-weeding process include mulching your lawn, whereby you add a layer of manure or organic matter to encourage healthy grass growth; carefully pulling weeds out with your hand, being sure to remove the whole plant at its root; fertilising your garden; and of course, watering and mowing it. Yep, these cordless lawn mowers could certainly come in handy.
How to use a weedkiller without harming wildlife
Some weedkillers are very harmful to wildlife garden ideas, particularly those high in glyphosates. Unfortunately this is one of the ingredients that makes them so effective at killing plants quickly, so if you do use a weed killer containing glyphosate, avoid use when pollinating insects are busy doing their job through spring and summer. They are more likely to be in danger if you spray the product on plants they are collecting from, and a bee could take this poison back to their hive with devastating results.
Also think about other wildlife like hedgehogs and frogs who dwell on the ground and might come into contact with a sprayed plant. If possible, section off the area of patio or driveway you are treating to keep them away, and use the product in the day when nocturnal animals are not snuffling around for food. For fast acting weed killers that work inside a day, you will need to remove the dead weed with gloved hands.
Don't forget, if you're looking for more ways to get your patio looking its best, then our guide to the best patio cleaner is great place to start.
