Often, you want to make sure no plants grow in pebble-covered areas. For those purposes, we recommend Roundup 365. It not only kills any existing weeds, but it also prevents plants from growing in that area for up to 1 year after spraying. It’s a great option for fighting back against pebble-invading weeds.
There are several good weed killers that will get rid of weeds growing through pebbles. Glyphosate-based weed killers, such as Roundup, are good for killing weeds in pebbles because glyphosate kills the weed membrane and washes out of the soil relatively quickly. As long as you don’t spray any nearby desired plants with Roundup, they should be unharmed.

There are even more drastic measures, such as preparing your soil with sand and/or mulch before laying landscape fabric and pebbles, as well as flame weeding. We’ll discuss all of these methods so you can choose the best way to keep weeds out of your pebbles.
