A couple of years ago I posted asking how to get rid of an enormous 30 year old pampas grass. The replies indicated that it was all too much hard work so I shelved the idea and we left it. Or rather, we continued the annual shave that it seems to have thrived on to date.
Well, this year it seems to be virtually dead. One or two green leaves emerging from a mountain of dry, dead stuff. It's pretty much kaput.
So, did the cold kill it? The only other thing I can think of is that about 15 years back I planted a walnut tree next to it which now spreads over the stump. Or do they just die of old age?
