How to Remove Large Pampas Grass Clumps Effectively

Q: How do I get rid of two large pampas grass plants? Can I burn them? Dig them up?

Burning fails because roots are insulated by soil. Instead:

1. Cut clumps down to 6 inches.
2. Run a lawnmower over the stumps repeatedly. Weak regrowth will eventually starve the plant.

If you need the space for new plants, sharpen a shovel and slice out root sections from the edge toward the center—it's heavy work but effective.
