Best Weed Killer for Pavers: How to Get Rid of Weeds

Any plants growing between pavers would be considered weeds since you don’t want anything growing between your paving slabs. Killing weeds between pavers or around pavers edging can be done in various ways. You can use a knife to cut the weeds from between pavers. This method is the most environmentally friendly but is time-consuming, and the weeds will likely grow back each year.

A more effective solution may be to use a post-emergent product such as Roundup, which will kill existing weeds. Pre-emergent herbicides can also be used at the beginning of the growing seeds. These do not kill existing weeds but prevent new weeds from growing. Let’s look at the best weed killer for pavers.

Things to consider before choosing the best weed killer for pavers

Best Weed Killer for Pavers

You should consider the other plants in your garden before using weed killer if you have desirable plants that herbicides may damage. You can use either a pre or post-emergent herbicide to kill weeds. Post-emergent is more effective on existing weeds that are growing between paving slabs.

Pre-emergent herbicides

Pre-emergent herbicides control weeds between pavers by preventing weed seeds from sprouting in the first place. Pre-emergent herbicides can be used around pavers in the early spring before weeds begins to grow.

The herbicide coats the weed seeds and prevents the seeds from germinating and growing into weeds. These types of products are best applied in the early spring or late fall. The exact timing will depend on your local climate and whether you want to control summer or winter weeds between pavers.

Post-emergent herbicides

If there are existing plants between pavers, then post-emergent herbicide can be used. Post-emergent herbicides are best applied after rainfall and can be used any time during the growing season. Post-emergent herbicides work by killing existing weeds and preventing new ones from sprouting up between pavers. Most post-emergent herbicide products have labels that specify how to use them around pavers.

Roundup is one of the most common post-emergent herbicides used by homeowners. It contains chemicals such as glyphosate, which is non-selective, which means they can damage desirable plants if you apply them incorrectly. For best results, spray the weeds whenever they are growing actively and before the weed seeds are released into the air. This is when the herbicide is most effective.
