It's well-nigh impossible to kill pampas grass - I cut or burn mine down to ground level every spring (though I have done it in winter too) - the roots are like concrete and would be impossible to shift, should I ever decide it has become too monstrous. I think any but the very young would be difficult to split. It seems the more cruel I am to my pampas grass, the more it likes it - really severe treatment, especially at the wrong time of year, only encourages it to grow even bigger and produce even more flowers! I think it has a penchant for Lady Whiplash.
