Ditto what Ron said. Are there a couple of dead branches on their side? Those could be cut out. BTW, any part of a tree that hangs over a fence into neighboring yards can be cut by said neighbor but they cannot kill trees they cut. Are any of their deciduous trees hanging into your trees & into your ‘air space’?

I'll see if I can get a photo on their side, just trying to do some research in advance before talking to them about it and snapping photos :) The note also mentioned they were very ugly and blocking the light from her garden, so that made my wonder if its really the trees or more to do with sunlight. So should I try fertilizing them and if so, with what? I guess the tree furthest on the left thats tucked behind the middle one a little, might be a little less full than the others, but its a different species so maybe thats normal..

Very few conifers - what you are calling evergreens - are happy in much shade. If the neighbor's deciduous trees are blocking sunlight to your conifers/evergreens then that would account for dead looking branches on the neighbor's side. Fertilizer won't help - this is a sunlight issue. If your trees are not overhanging her space, then there is nothing you need to do. But the dead areas will remain as long as the trees do not receive adequate sunlight. Crowding them or planting too close to each other can also have this effect.

I like what I'm hearing! :) Thanks!

I had the same problem where one of my trees shaded an evergreen. It had so many dead branches that I finally took it out. The dead side was visible to me though.

Your neighbor's trees look pretty dense. They could try thinning them to allow more light in, but in my experience, it just encourages the tree to grow more branches in the open spaces.

Being a good neighbor to your fussy neighbor, you should prune off the dead branches on your trees.

That's a good idea maybe it will give them a bit more light over there too without the dead branches...

Blocking the light from their garden ? Your trees are fairly old ,,maybe 20yrs ,,how old is their garden ? Are their tree also shading their yard ???

"Blocking the light from their garden ? " Who cares?! They are on YOUR PROPERTY. I have an allée of Southern Magnolias I planted years ago, they are now four stories tall and partially shading their pool, in a few more years, they may impact the solar panels of the neighbor next door to them. Not your problem!

My guess is they get too much shade on that side. If they look good on your side and you like them, then keep them.

Just also keep in mind, legally, if they are growing over their property, they have a right to cut the overlapping branches.

if shes willing to pay for removal.. what the heck.. let her live her dream... you can plant some much cooler stuff....

if not ... tell her to go screw herself... or some more polite alternative.. lol ...

any chance her name is karen ... and she is part of the hoa??

who really cares if prunes the side you cant see... on her side of the fence.. its on her property..... and whatever.. you cant see it anyway ...
