killing a tree stump

[daz lord]

i cut down a sycamore with a 2 foot diameter trunk 18 months ago covered it in diesel and wrapped it it in plastic to rot it,this didnt work and the ting has started to grow again can any tell me what i should do next,

[Thunderbird+]

Yes daz they can be very persistant,
Try drilling some holes close to the edge of the stump,all the way round, approx 1"x 1" deep, fill with rock salt and plug the holes with clay.
Break (rather than cut) any branches that have re-grown from the stump.
Alternativly, you can buy products such as 'Rootout' or 'Deeproot' to do the job and follow instructions.
Good Luck Tbird+

They are tough trees and as Thunderbird has already suggested, Deeproot is good stuff. It takes time to do the job but it is successful.

As tree surgeons we would cut a section about 2" thick off the stump then deeply score the stump with chainsaw put loads of rootout on the surface and nail the 2" section back on. works every time!!

It apparently also works if you pee on it regularly!!!
