Invasive plants can cause a lot of trouble by disturbing the natural balance of our environment. They can take over and push out native species, disrupt local ecosystems, and reduce biodiversity. While some of these plants may seem attractive or grow quickly, they can cause long-term problems in your yard. Here’s a list of 11 common invasive plants you should avoid planting, along with some tips on how to manage them if they’re already present.
1. English Ivy
