Question:
What type of barrier should I use to keep monkey grass out?
​​
Answer:
It can be hard to kill monkey grass (liriope) because it has a deep root system with lots of energy storage. To remove it you may need to dig it out by hand. It will be hard to keep it out of an area with a barrier. The barrier would need to be deep and impermeable to the roots.
