We have 4 poplars in our garden which are about 30/35 foot high. (These are not protected by the way) and need to get rid of them as they are causing problems.
Would it be possible to ensure they are dead without actually taking the whole tree and base out. Eg. just cutting it down to a stump and using a root killer? we have consulted a local tree surgeon and he says this will kill it.
Thanks
