Injecting the roots with a glyphosate based herbicide in the autumn works well. In the roots on my side of the garden of course.
If the trees are that bad you could alsways get a court order for 'rites to light' which can be enforced but it would all depend on the type of trees, if they are evergreen, you could possibly go down the legal route. (bloody expensive mind you) If they are not stick to the glyphosate based herbicide , if the trees are over hanging your property / land - YOU can cut them back to where your fence ends (no more) then you MUST hand her back the branches and leaves - that will piss her off having to get rid of the rubbish and a lopsided tree https://www.gov.uk/government/publications/rights-to-light
The sun rises to the left and tracks across the garden through the day being blocked by one tree after another then it goes behind next door's house. The leaves from the two trees on the right are ****in horrific in the autumn. Sometimes I feel like bagging them all up and offering them to her
hmmm interesting You can bag up the leaves that fall in autumn and leave them over the fence for her to dispose of, after all they are her leaves next time it gets windy, throw a rope around the one nearest to your property and snap the branches, pull them onto your side take photos then contact the council telling them how dangerous the trees are ....... maybe she will get pissed off enough with the amount you bag for her to dispose of, maybe enough to have the trees cut back to stop you leaving bags of leaves -- put your leaves in as well The bushes at the bottom of your garden....anything that overhangs your property you can cut back to the fence... again leave any cuttings or large branches on the other side with any leaves etc. bagged Looking at the fence... that belongs to her and should be maintained to a safe standard by her - she has a rite to enter your property (with your permission) to do this, she can go to court to get permission if you refuse, also cost would be award against you if you do refuse looking at your shed ....seems to be a lot of overgrowth there as well cut back to the fence, bag and leave over the fence the trees to right of the shed looks like they has been cut back at some point in the past you need to look straight up from the end of your property and see what overhangs your property if you want to cut back any large branches that over hang it maybe be best to inform your neighbour by letter giving them the opportunity to sort it out them selves first (the legal way)
My neighbours are sound. 12 houses in the street and I could name all of them i reckon, when my youngest was born the couple opposite brought over a hand-made card of her name and kept us supplied with apple pie/crumble and savoury dishes. The house on the other side is twice the size of everyone elses and they have big parties a couple of ties a year and invite everyone (they get caterers in and bar staff etc). 3 of the 4 gardens that border ours have kids the same age. It just works. We're talking about moving (not far) and one of the reasons we're debating not doing so is the nieghbours.
