Hi I have just moved in to a house with very large over grown leylandii. I have started cutting them back and topping them. Where they have been left for years there is a lot of dead branches underneath the green. After reading the comments here I'm in 2 minds to trim back to the trunk, if I do this will the tree be effectively dead and stop taking the goodness from the soil around it?
