im needing to replace the fence behind my trees but the trees need removing first. They are conifers around 8/9ft tall(60ish). Do these types of conifer have deep roots and need a mini digger to remove or are they likely to have a small root ball? I think they may be leylandi. Next part is how to get rid of the trees that are dug out, is this type of tree ever wanted for log burners or is it likely to cost a fortune to dispose of them?
