Tired Pampas

Many years ago my Hubby planted two Pampas Grasses in our front lawn. These have now grown to a ridiculous size and the centres are dying out - leaving plants which are a real mess.
I want to take them out and replace them with two new black Pampas. The problem is how do I kill the old ones? A neighbour told me to set fire to them a few years ago. I did and they got bigger!
Any ideas?
Please don't suggest digging them up - they are 8ft across and just as high!

we tied ours to our 4x4 and towed it out worked a treat :yess:

 

1) Cut them down completely to ground level and spray them with Touchdown or other Glyphospate product. You'll have to spray them a couple of times. When you keep mowing that area, any remmants will eventually die out.

or 2) Hire a mini-digger.

 

Or ... invest in a mattock. Great exercise and perfect for digging and cutting through roots. A marvellous tool.

You really HAVE to dig them out I'm afraid, either by hand or using a digger etc
I had one of similar size which I dug out after cutting down to ground level. The digging out of the rootball was done a bit at a time by splitting with a heavy axe into sizeable clumps
Better than going to the gym
