leylandii to screen out Industrial Building HELP PLEASE

Please help I realise that leylandii are not the most best things to plant, but then again I've just been told a 12 metre high pre-fab is being constructed alongside my house!!!!

I think that the green fast growing leylandii is the only thing I can use to avoid going insane looking at a metal prefab building.

The question is due to money consraints I need to start with 1 metre high trees. My question is to get a good screen up to 30-40 feet high how far part should I plant them. I'm not planning on shaping or cutting them just letting them grow. There will be no neighbours to anoy!!!!

Also on one other boundary I planted a 10 leylandii some three feet apart before I found out how hight the new building is going to be, can I dig these out a couple of months after they were planted and replant wider than three feet if this is what you advise?

Many Thanks for anyhelp you can give

 

I wouldn't use them as a screen in the circumstances you describe at all. Tooo dark and too uniform and too limiting in what you can do in front of it. As I understand it - you are going to have a 12m metal wall alongside your boundary (colour not stated). Me I'd think more breaking it up and turning it into a backdrop by planting different trees, including specimen conifers but giving you the scope to plant in front - and more pleasing to the eye than leylandii on mass - you can get really mature trees and colourful trees if you look around, and as long as you prepare the ground well, should do fine at breaking an eyesore up.

Sorry - just thinking what I would do faced with that - depending on the closeness to the house.

 

Yes I quite agree with Fran,
Try to add some Silver Birch and evergreens such as Holly or Holme Oak (Quercus ilex )transplants or whips would be ideal as they are quick to establish, may be try some of the cell grown trees from Cheviot Trees as these can be planted now ( if it is not too dry a site )
