Will I get weeds in my artificial lawn?

I'm quite worried about weeds growing in my lawn.

Occasionally, weeds can grow through the artificial grass drainage holes. Weed is a very stubborn type of plant that grows anywhere.
There is a way to prevent or minimize the weeds problem: At the installation, you can use a layer of weed barrier, we carry this product which you can find at this link:

If you have already installed your artificial turf and didn't use weed barrier, no worries, you can use weed killers such as Roundup to get rid of the weeds, just be careful when spray such weed killer as you might want to wear face masks and gloves to minimize your exposure to those type of chemicals.

It's possible but I think they can be easily removed.

I couldn't agree more with Elbert. You have to prepare the area and add some layers during installation so you could avoid the use chemicals as much as possible, once it's installed. These chemicals are no good for your synthetic grass.

I used weed barrier for protection. I don't want to end up cutting overgrown weeds on my artificial grass.
