Palm stump
This is the stump of a multi-stemmed palm tree I had cut down nearly three years ago. (IMHO, palm trees look ridiculous anywhere north of the Mediterranean.) As you can see, it's still growing. I keep pulling off the green tufts, but it makes no difference. Last year, I decided I'd try and dig it out. I dug down about a foot (narrowly missing a water supply pipe I didn't know was there) and there are no side roots I can cut through, just the trunks going down and down like giant parsnips. Which makes sense for a plant intended by nature for an arid climate. I avoid chemicals like the plague, but there seems no hope of destroying it mechanically. Unless any of you clever clogs knows better?

What about trying a stump grinder?
Gardening in Central Norfolk on improved gritty moraine over chalk ... free-draining.
Drill deep holes and administer a glyphosate weedkiller ( Roundup is as good as any) .
Thanks for these. The tree man is coming in November to prune my lovely beech, so I'll ask him about grinding it. If I use glyphosate, is there some way I can seal it in to keep it from harming anything else? I know they say it's neutralised when it touches soil blah blah blah, they would say that, wouldn't they? I don't trust Monsanto.
It won't harm anything else ; just inject directly into root-stump .
