How to kill an Alder stump?

[Ferdinand]

I've taken a vigorous alder out my hedge by my lane, and need to prevent it coming back so the holly to fill the gap gets a decent run.

 

It is too big to dig out easily, so I want to poison it. Any suggestions?

 

I have copper sulphate available and apart from that probably only a couple of root weedkillers (ie glyohosate) which will be no good for this.

 

Will drilling a hole or two and packing with copper sulphate do the job?

 

Thanks

Glyphosphate will do it. Drill a few holes, pour it in and leave to rot.

I have recently had thirteen trees cut down and several were large sycamore and ash and I drilled 22mm holes in the stumps and filled then with neat SBK. I will hammer 22mm copper pipe in when I get round to it as that is the old recognised method of killing stumps, slow but sure.

Give the ones with glyphosate to Hufflepuff, who sound like the people on the "B" Ark Ship from Golgafrincham.
