Anyone who has ever done a spell of weeding knows what a back-breaking chore it can be. Sometimes, especially in spring and summer, you just can’t keep on top of the weeds and barely have the aches and pains from your last purge gone before you have to begin all over again.
No one appreciates their lawn, bedding areas or pathways clogged up with weeds and weed killers can provide a very effective solution. That is, however, providing you understand a little about them and choose one that is suitable for your purpose.
Weed Killer Buyer’s Guide
It is perfectly understandable for someone to want to buy the best weed killer UK wise and that’s fine, providing it will do what you want it to do. For example, if applying herbicide is going to be your first step in trying to cultivate a beautiful lawn (see our guide on the best grass seed), you will need the best lawn weed killer. If it’s those blighters popping up between your paving stones, you will be looking for the best product for block paving. How do you find the best weed killer for ivy when some people swear that only vinegar works? Do you get the idea?
It helps if you know the type of weeds you are tackling so that you can seek out products tailored to deal with them. The severity of your problem and the welfare of your lawn, surrounding plants and flowers will also influence your choice. You will need to decide whether you need a selective herbicide, which kills the weeds and leaves plants unaffected, or a non-selective one, in which case every plant in the treated area will die.
Using Weed Killer Around Pets & Children
When using a weed killer, caution needs to be exercised around children and pets, so choose one that is safe or becomes safe quickly after application. Some products can cause a threat to aquatic life, so if you keep fish in a garden pond or live in a rural area and are visited by frogs and toads, take care. There are also wider environmental things to consider, such as the well-being of the bee population.
You also need to decide whether you want something that kills the weeds when they are germinating and before they emerge or after they have grown. Non-selective products stay in the ground for a long time preventing further growth. Non-persistent herbicides kill the weeds but quickly become inactive and so are particularly suited to properties visited by children or where there are pets.
Finally, do you want the product you are using to kill the weed as soon as it touches it, in other words, a contact herbicide, or do you prefer a translocated herbicide that will act more slowly, penetrate into the cells of the weed killing it and its roots from the inside?
These are the considerations you need to make as I waltz you through some of the best products on the UK market this year.
