Weed Killer Buyer’s Guide
Hopefully, our list of the best weed killers on the market will have encouraged you to choose one that will help you manage your garden weed issues. However, with so many different types available, you may still have questions about the different kinds of weed killers that are on the market, and which might be best for you. To help you answer a few of these questions, we’ve compiled a Buyer’s guide that will hopefully shed some light on the different options available.
Selective or non-selective?
When it comes to weed killers, two main options are available: Selective and non-selective.
Selective weed killer targets specific plant types and weeds. This could be as specific as targeting broadleaf weeds, creeping vines or flowering weeds, or could more broadly target grassy weeds or woody plants. The benefit of this type of weed killer is that it won’t damage desirable plants, and can be used on lawn and turfgrass without creating a dead patch.
Non-selective weed killer will target any plant that you aim it at, and will usually require you to soak the foliage of the weeds. This type of killer isn’t great for spot use, or clearing weeds in areas where you want certain plants to remain, but is ideal for full weed control around fences or buildings, or controlling your lawn growth.
Preventative or killer?
If you have weeds that are currently infiltrating an area of your garden, then you will need to purchase a weed killer that will exterminate the plant. Ideally, you will want one that targets the roots as this will prevent any weeds from growing back, and will leave the area permanently clear.
For treating an open or un-planted area, you need to pick up a product that works as a weed preventer. This will leave residual chemicals in the soil that will stop plant growth. Some are specific, allowing the ground to be replanted soon after application, whereas some are all-purpose and will prevent all plant growth, sometimes for up to a year- so you won’t be able to replant the area.
Though this isn’t suitable for flower beds and lawn areas, a preventative like this is perfect for keeping areas near fences and buildings clear of weeds and provide a permanent solution to weed growth.
What is the best option if I need to replant the area?
There are a few products that are perfect for those of you who need to replant the area soon after use. Look out for the weed killers that have no residual effects, as these will only target plants that are currently growing and will not prevent any further growth of new plants.
As well as this, if you grow edible produce in your garden, you want to pick out a weed killer that is natural and safe to spray near edibles. These may not be the most potent weed killers on the market, but they are likely the best weed killers available for those who want a product that is safe for crops.
These types of weed killers are also the best weed killers for families with children or pets as they often dry fast and are non-toxic, meaning that any accidental consumption isn’t going to cause any harm.
There is a lot to consider when searching for an effective weed killer for your garden. There are many products all claiming to be the best weed killer you can buy, each with their own benefits and special features. Hopefully, our article and buyers guide will have helped you decide which product is the best weed killer for your needs, and you will now be on your way to a weed-free, tidy yard and lawn.
