I have recently bought a new house and there is a 15ft Yew outside my house (within the boundaries of my wall). It blocks light and I would like to either: - completely uproot it - trim it to about half the size I have been warned against both for different reasons. Someone told me not to completely remove it because it could cause the land to sink where the roots extend to (Its about 4m away from my front door). Also that the roots are sucking up lots of water which could lead to excess water beneath my house?? Also been told that cutting it back by half would be difficult and it could take years before it goes green again. What would you advise?
