Best weed killer for your lawns in 2019 - How to Choose?
Please note from the beginning that some of the products are the best weed killer for lawns that are old and that you wish to remove altogether before replanting with a fresh new type. These types are also suitable for clearing a piece of ground of all weeds and unwanted vegetation before planting a brand new lawn. Other products are suitable for spraying onto an existing lawn that is infested with weeds. The weeds will be killed but the grass unharmed.
Before choosing what you think is the best lawn weed killer, the most important thing is to identify exactly what kind of weeds are growing in your turf. This will determine what kind of product you choose. You need to be careful about this, as choosing the wrong one, or using too strong a mix, can damage or kill the lawn as well. Some weeds are resistant to the chemicals, and will need to be sprayed more than once. Take note of whether the weeds are annuals, such as crabgrass, or perennials (more difficult to control) such as dandelions. Your local nurseryman or garden center will probably be familiar with the common weeds in your area. If you’re struggling with identification, just dig out a sample and take it into the shop for advice.
It’s also important, before purchasing the best weed killer for your lawn, to establish what you’re trying to achieve. Are you trying to prevent weeds from growing in the first place? (In which case you’ll need a “pre-emergence” herbicide, which is usually applied in spring.) Or are you trying to solve an already existing weed problem? In this case, you’ll need what is called a “post-emergence” herbicide. Some of these are selective and only target, for instance, broad-leaved plants, while others will kill anything green and growing. These ones, obviously, will not be the best weed killers for your lawn, but are best used on paths and edgings.
You’ll also need to decide whether to buy a concentrated herbicide- ideal for if you have a large area to spray, or a ready-mixed spray. These are best for small spaces.
What follows is a selection of five herbicides, one of which you may decide is the best lawn weed killer for your purposes. We’ll discuss the pros and cons of them all, so that hopefully at the end you’ll have a better idea of which one is most suitable for your needs.
