Has anyone got any idea on ■■■■■■■■■■■ one? i dont want to have to dig it out as the roots go all the way to hell and back.
Any help would be appreciated.
Cut it back to 6-9 inches high, drill out the stumps & put some Sodium Chlorate weed killer in the hole & then tape it over to stop it killing kids & animals.
Sodium Chlorate is the very cheap weed killer you buy in little tubs. it makes the ground un-usable if used on the soil, but I have removed several shrubs in the middle of other plants in this way without loosing any other plants.
It could be a little time consuming, but don’t forget that doing it this way it will kill the roots in the ground so you only need to hit the main stumps to kill the whole thing.
4 wheel drive and a chain 
red deisel
or place some copper wire round the bottom that will kill it
Agree with daxi - use Sodium Chlorate.
I used it to kill off some plants in my garden that I wanted to get rid of. Mixed it with water and put it on with the watering can. Works within a matter of hours.
