Topping a spruce
Our property is lined with several large spruce trees ~50ft tall. Two of the trees are a few feet from our neighbors garage. The neighbor would like to " top off" the trees in order to make them stronger and therefore less likely to fall (his words). I don't want to do this for aesthetic reasons but is there any validity to what he is telling us?

Topping conifers is never a good idea. Topping trees leads to continued maintenance and a very un-natural form. Trees that are topped maybe more prone to attack from insects and diseases.
