I own (well, joint-own, but let's keep this simple) my house. It has a garden at the back, not huge, but not tiny either. The house is tucked away on a niceish cul-de-sac off the side of a slightly grotty estate. It's at the end of a terrace, with a school playing field to one side, and gardens to the other side and rear. There's a nice amount of big vegetation in the garden - enough to give the illusion that the house is somewhere slightly nicer than it actually is. I like my trees. One tree in particular dominates - it's at the bottom of the garden, and is about 20 or 30 feet tall with a wide canopy. I'm not sure what type of tree it is - maybe a Beech? I'd have to check. This tree grows in a slightly awkward fashion - it's right by the bottom fence, and grows sideways over the boundary at a height of about 3 feet, after which it curves upwards, and splits into two main branches at a height of about 4 feet, each about 9 inches in diameter, one of which grows further away, across the next couple of gardens, the other of which grew (note the past tense) close to vertically, slightly back towards my garden. Looking out of my kitchen window a couple of days ago, I spotted that substantial parts of the tree seem to be a lot nearer the ground in my garden than they used to be. Popping out to investigate, I found that the trunk has split vertically downwards for about a foot and a half between the two main branches, resulting in the half of the tree that grows in this direction putting some undetermined portion of its substantial weight onto the side fence of the garden as it sagged down. So, what should I do? I don't want to have to have this tree cut down, but I'm not sure its salvageable. Options seem to me to be: 1) Leave it as it is; both halves still seem to be alive. But then wouldn't it just split further in future, and eventually come tumbling down? 2) Me cut off the half that is dangling into my garden. But then would the strength of the roots be sufficient to support the now rather unbalanced weight of the tree? It would be a disaster if it fell over away from my garden - it would crush two sheds and somebody else's fence - not to mention threaten life and limb! 3) Pay a tree surgeon to look at it - and probably take it down. This is certainly the most responsible course of action - but how much does a tree surgeon cost? There is a fourth possibility - the scumbags who are tenants of the garden at the bottom have previously vandalised to the point of destruction the fence separating my property from theirs. Their landlords have offered previously to replace the fence, and to take out that tree as part of the process (I asked them to wait until their tenants are gone - they are to be evicted on Sept 6th) - it's probably worth speaking to them to see if they are still willing to make good on that promise... I can post photos if they would help... Thanks!
