How To Use Catnip As A Companion Plant

Catnip can be used as a companion plant in the garden to help keep away unwanted insects and other pests. It also helps attract honey bees and other pollinators to the garden. The oils that the catnip plant contains are what keeps bugs away, they do not like it at all. By using catnip as a companion plant you can avoid using harsh chemicals as a way to keep harmful insects and pests out of your home garden.

Catnip can be a very invasive herb. So when using catnip as a companion plant it is best to plant your catnip in a container. You can then either sit the container of catnip near your crops that you are using it as a companion plant for or you can plant the container in the ground.

Make sure where you place your catnip is an area that has some room around it. And don’t plant it right next to your vegetables or other companion crops. Just like the catnip you buy in a jar, cats will love this plant even when it’s growing in your garden. You will often find cats rolling around your catnip in the garden, so make sure they have room to do this without crushing your garden crops.
